S01. Integrating mobile computing technologies into traditional archaeological methods

Dr Ying Tung Fung, Hebrew University of Jerusalem and University of Oxford

Session type: Standard

Although mobile computing is not new to field archaeology (Ancona et al. 1999), it is not until the past two decades mobile devices and applications have become more common. This gives us a more efficient way to collect and record data and allows us to put data in relational contexts easily (Wallrodt, 2016). The digitalising technique is replacing the traditional paper forms in a positive way, but it is still evolving and needs improvement for a better integration between the design of mobile applications and conventional archaeological collection and recording methods. Archaeological projects usually involve a large amount of data, which cannot be easily recorded, organised and stored without any hassle. Mobile devices and applications provide many benefits for data collection process as survey and excavation points and polygons can be marked in software such as ArcGIS and GPS applications in advance. Data can be recorded and uploaded by multiple team members to mobile devices offline and then to computational devices to build up master datasets and relational databases, which are ready to be used for computational analysis.

However, paperless documentation is still new and there are still obstacles we have to overcome. For example, we have several cases of using mobile devices such as PDA and iPad (e,g, Canals et al., 2008; Ellis, 2016; Gordon et al., 2016; Motz, 2016) as well as custom-developed mobile application (e.g. Fee, 2016) to record data, but these applications have their limitations and challenges. Developing a new application requires extra works and cost to make it available on different operation systems and future maintenance are needed for long-term project, while using existing software limits the ways of which data are recorded and collected for specific archaeological project (Wallrodt, 2016). There are also technical problems such as features setting, choosing a suitable database model and exporting data to computational devices (Fee, 2016), and problems in applying the digital methods in different regions around the world especially the developing regions (Sayre, 2016).

Along with the continuous advancement of mobile applications and devices in recent years, the above issues have been minimised. Open-source applications such as FAIMS Mobile and HumanOS provide customisation services for specific projects (Ballsun-Stanton et al., 2018; Colleter et al., 2020). Other free and open-access applications such as DigApp and TaphonomApp allow a more flexible operation as they can be easily modified by users (Martín-Perea et al., 2020). The innovation of the device iPhone 12 pro LiDAR, meanwhile, provides a new way to scan and record features using mobile devices (Cohen-Smith et al., 2022). It is timely to evaluate the advantages and limitations of applying these new applications and devices in archaeological research, and how to better integrate mobile computing methods with traditional archaeological recording methods.

This session welcomes papers that discuss and evaluate the new mobile applications and devices in archaeological collection and recording processes. The topics include, but not limited to: the use and review of innovative mobile devices and applications in archaeological projects, the benefits, limitations and challenges of using these applications and devices. As well as how to overcome or minimise problems to improve the integration of mobile computing technologies with traditional archaeological methods, and suggestions and prospects for future development of using mobile computing in archaeology.

S02. Studying uncertainties in archaeology: A new research agenda

Eduardo Herrera Malatesta, Center for Urban Networking Evolutions, Aarhus University
Tom Brughmans, Center for Urban Networking Evolutions, Aarhus University

Session type: Standard

Archaeology and landscape research have greatly benefited from the increasing application of computational methods over the past decades. Geographical Information Systems (GIS) and spatial statistical methods such as point patterns have been revolutionary for the discipline. Furthermore, the analytical power of studying spatial relationships between objects has been enhanced through the use of network science for archaeological landscape research. However, the results obtained from these techniques can be greatly affected by the many uncertainties imposed by the fragmentary nature of archaeological data, particularly when they are derived from non-systematic surveys. Since the 1960s, archaeologists have tried to solve this by developing more systematic fieldwork methodologies such as total-area survey strategies. Yet, this methodology cannot be applied to every region; therefore, non-systematic survey strategies must be followed. This poses methodological challenges when attempting to apply GIS, spatial statistics and network analysis methods to such fragmentary and uncertain datasets.

For example, while in archaeology it is common to use statistical methods to deal with partial data in point pattern analysis to study regional patterns, this does not provide information to assess the actual levels of uncertainty of a particular regional dataset. Furthermore, at the moment there is no formal study of the uncertainty levels for the computational models resulting from applying the mentioned methods to a non-systematic regional dataset. While the study of uncertainties has seen recent debates in archaeology, it is still an underdeveloped topic. Particularly, previous attempts of quantifying uncertainties for archaeological data have not aimed at creating overarching solutions or resources tailored for the discipline, i.e., a protocol or software.

This session aims at bringing together contributions that present concrete and original research on the quantification of archaeological uncertainties from any archaeological spatial and temporal perspective. Contributions should look towards the creation of overarching solutions for archaeological uncertainties and for the formal application of uncertainty methods and analysis. For this, each presentation should contain 1) a concrete research problem and case study, 2) a concrete description of the used methods, 3) a clear walkthrough of the application of the methods (with accompanying code when available), 4) concrete results, and 5) a concrete discussion on the interoperability of their methods and results for other case studies. Paper topics of particular interest to this session include but are not limited to:

  • Systematic description of sources of and types of uncertainties in archaeological data,
  • Uncertainty in landscape archaeology,
  • Uncertainty in network research,
  • Methods for quantifying uncertainties,
  • Sensitivity analysis approaches,
  • Protocols, methodological pipelines or standards for uncertainty quantification,
  • Coded implementation of uncertainty quantification methods,
  • Aggregation of uncertainty quantification methods in toolboxes for our community,
  • Case studies addressing the above for any region or time period.

This session will provide a platform for sharing experiences, strategies, and methods for archaeological research on uncertainties. Our ultimate aim is, together with the participants, to outline a new research agenda for the formal application of uncertainty quantification methods, for both non-systematic survey data and computational models, in archaeology.

S03. Our Little Minions pt. V: small tools with major impact

Moritz Mennenga, Lower Saxony Institute for Historical Coastal Research, Wilhelmshaven, Germany
Ronald Visser, M.A., Saxion University of Applied Sciences, Deventer, Netherlands
Brigit Danthine, M.A., Austrian Archaeological Institute (Austrian Academy of Science), Austria
Florian Thiery, M.Sc., Römisch-Germanisches Zentralmuseum, Mainz, Germany

Session type: Lightning talks (max 10 minutes)

In our daily work, small self-made scripts (e.g. Python, R, Bash, Haskell), home-grown small applications (e.g. GIS Plugins) and small hardware devices significantly help us to get work done. These little helpers -“little minions” – often reduce our workload or optimize our workflows, although they are not often presented to the outside world and the research community [1]. Instead, we generally focus on presenting the results of our research and silently use our small tools during our research, without even pointing to them, and especially not to the source code or building instructions. This session will focus on these small helpers – “little minions” – and we invite researchers to share their tools, so that the scientific community may benefit. As we have seen in last year’s “minion talks” since 2018 there is a wide range of tools to be shared. This already fifth Little Minion session invites short presentations, lightning talks (max. 10 minutes including very short discussion) – of small coding pieces, software or hardware solutions in any status of completion, not only focusing on fieldwork or excavation technology, associated evaluation or methodical approaches in archaeology. Each talk should explain the innovative character and mode of operation of the digital tool. The only restriction is that the software, source code and/or building instructions are open and are or will be freely available. Proprietary products cannot be presented, but open and freely available tools designed for them. In order to support the subsequent use of the tools, the goal should be that they are openly and available to the scientific community (e.g. GitHub, GitLab). We invite speakers to submit a short abstract including an introduction to the tool, the link to the repository – if possible – to get access to the source code and an explanation of which group of researchers could benefit from the little minion and how. The tools may address the following issues, but are not limited to (you will find an overview of the previous sessions under -data processing tools and algorithms -measuring tools -digital documentation tools -GIS plugins -hands-on digital inventions (e.g. for excavations) -data-driven tools (e.g. Linked Data, CSV, Big Data) After previous years (pt. I CAA 2018 Tübingen, pt. II CAA 2019 Krakow, pt. III CAA 2021 Limassol/virtual, pt. IV CAA 2022 Oxford/hybrid) spontaneous success of “Stand-up-Science”, you will also have the opportunity to spontaneously participate and demonstrate what you have on your stick or laptop. If you want to participate without an abstract in the spontaneous section of the session, don’t hesitate. Please come and spontaneously introduce your little minion! The minion session is designed for interested researchers of all domains who want to present their small minions with the focus on the technical domain and also for researchers who want to get ideas about what kinds of little minions are available to help in their own research questions. All of us use minions in our daily work, and often tools for the same task are built multiple times. This online session gives these tools that are considered too unimportant to be presented in normal talks, but take important and extensive steps in our research, a home. As an outcome of the session, we try to give support, that all presented tools and links to code repositories will be available for the research community on our website

S04. “Hey Google, stop that looter”: digital technologies against cultural heritage crimes; critical approaches, ongoing solutions and beyond

Arianna Traviglia, Center for Cultural Heritage Technologies – Istituto Italiano di Tecnologia
Michela De Bernardin, Center for Cultural Heritage Technologies – Istituto Italiano di Tecnologia
Riccardo Giovanelli, Ca’ Foscari University of Venice and Center for Cultural Heritage Technologies – Istituto Italiano di Tecnologia

Session type: Standard

Countering the devastation of archaeological sites caused by illegal excavations or voluntary destruction is at the forefront of worldwide governments agendas, but also cultural institutions and caring citizens are deeply concerned by this disruptive phenomenon. Looting (i.e., the unlawful removal of ancient artefacts conducted through non-scientific methods by robbers) is an old practice, dating back to ancient times. Recent events such as the 2004 Iraqi war, the 2011 ‘Arab Spring’, ISIS’s actions in the Middle East and North Africa, the COVID pandemic and the 2022 Ukraine war, determined a spiralling increase in looted items being available on the international antiquities market, both the legal and illegal ones. The last decade witnessed a growth in computer-aided technologies designed to monitor both looting activities and art markets, tools that have proven to be highly instrumental in halting/detecting unlawful behaviours. Remote sensing is being used to detect and monitor illicit excavations (Tapete and Cigna 2021) using multispectral imagery – investigated through both manual (Casana and Panahipour 2014; Contreras 2010; Stone 2008) and automatic recognition of looting patterns (Lasaponara and Masini 2021) –, SAR data (Tapete, Cigna and Donoghue 2016; El Haji 2021) and Multi-Temporal Analysis (Agapiou 2020). VHR imagery time-series deployed by Google Earth makes it now possible to locate several looted sites throughout the globe (Contreras and Brodie 2011; Parcak et al. 2016; Zerbini and Fradley 2018), opening avenues for the development of new methods of recognition. The potential of computer vision and machine learning methods applied to web-scraped content (Huffer and Graham 2018; Huffer, Wood and Graham 2019; Graham et al. 2020) is being investigated to track illicit on-line sales. Network Sciences derived methodologies have been studied to identify criminal networks of the antiquities trade (Tsiriogiannis and Tsiriogiannis 2016) and its actors within the so-called “grey market” of antiquities (Bowman 2008; Mackenzie 2019; Mackenzie and Yates 2016). Artificial Intelligence approaches are being developed to identify looted/robbed archaeological items appearing in the market (Winterbottom, Leone and Al Moubayed 2022). The monitoring, both manual and automatic, of Social Media, on-line forums and marketplace, as well as the deep web, is enabling to gather crucial information about the illicit market using both quantitative and content data (Al-Azm and Paul 2019; Hardy 2014, 2015, 2017, 2018; Paul 2018; Giovanelli 2018; Altaweel and Hadjitofi 2020; De Bernardin 2021). Databases of stolen objects and due diligence activities have been developed by enforcement units, such as the Comando Tutela Patrimonio Culturale in Italy and INTERPOL (Arma dei Carabinieri 2016). 3D imagery-fed blockchain technologies (Gandolfi and Cox 2018) are currently being investigated. The progresses of research in this domain are fast-paced and pushed by the increasing loss of archaeological contexts and Cultural Heritage items. The developed technologies are getting more specialized; however, they are often unable to achieve levels of sophistication that can concretely contribute to the fight against illicit trafficking. This session invites the submission of original papers in the areas outlined above (i.e. remote sensing, network sciences, computer vision, machine learning, data-mining, blockchain, qualitative and quantitative SM data analysis) and beyond that engage in a critical discussion on the approaches, solutions and outcomes of established and emerging technologies, in order to highlight the pros and cons of technological applications and to identify successful means and methods to concretely build systems able to fight and prevent the looting and the illicit trade of cultural heritage objects. We are also interested in new methods and applications that have not been fully explored yet in the domain of countering cultural property trafficking, but which should be taken into consideration for future developments, such as in the field of Network Sciences and Graph Theory. The session is mainly intended for researchers working in the broad domain of antiquities crimes using traditional and computational approaches; it also benefits those working in the described technologies and methods (remote sensing, machine learning etc.) in the broader context. The session is organized within the framework of the HORIZON EU RITHMS (Research, Intelligence and Technology for Heritage and Market Security) project, which aims to create an innovative, interoperable, and multifunctional Social Network Analysis (SNA) digital Platform able to identify criminal organised networks involved in trafficking of cultural property, thus providing investigators with valuable intelligence about the activities and evolution of those networks to support the prevention of future criminal offences.

S05. For new epistemologies in Archaeology: using probability, networks and mathematical models to build archaeological knowledge

Joel Santos, FCSH Nova Lisbon University
Daniel Carvalho, UNIARQ, LAQU, FCT

Session type: Standard

Investigating the complex nature of the human past is of paramount importance to archaeology. Throughout the years, several theoretical proposals on how to perceive the past have been constructed. From formulating law-like statements (Binford 1972; Schiffer 1976) to symbolic and contextual approaches (Hodder and Hudson 2003), passing to symmetrical and ontological critiques (Olsen 2013; Olsen and Witmore 2015), archaeological theory has experienced change and shifts in relative interest in the last several decades. However, a fundamental question arises: how are archaeologists able to face the near infinite possibilities that constitute the past? On top of this already difficult conundrum, the basis of our work is nothing but fragmented material remains, mere shadows of things that once were. Is this an impossible task?

We believe not. By applying methods and ideas with a strong mathematical basis, archaeologists can strive to reduce subjectivity and engage with a larger realm of questions. For example, the Bayesian approach used in Archaeology has increased in the last decades (Otarola-Castillo and Torquato, 2018; Otarola-Castillo, Torquato, and Buck, 2021), being applied in the most different areas, but is it possible to increase its application from chronological modeling using radiocarbon calibration (Buck et al., 1991; Price et al., 2021), bioarchaeology (Konigsberg et al., 1992; De Angelis et al., 2021), zooarchaeology (Fisher, 1987; Baumann et al., 2020), artifact analysis such as lithics or ceramics (Buck et al.,1996; Murray et al., 2020) or spatial analysis (Kirkinen, 1999; Wright et al., 2020) to archaeological theory and epistemology?
The objective of this session is to explore frameworks that are able to embrace a sheer volume of possibilities that shape complex events of the past, demonstrating how to build a sturdy epistemological basis. We intend to explore Bayesian methodology, Network Theory and AI theory and applications to discuss multiple ways for constructing hypotheses about the Past. With this premise in mind, we welcome papers that:

• Propose ways to build archaeological knowledge with methods from analytical and statistical backgrounds (e.g Mathematics, Computer Engineering);
• Embrace social, economical and political questions in archaeological contexts while dealing with great amounts of data;
• Using algorithms to construct hypotheses for archaeological endeavours;
• Explore novel paths in the creation of theoretical viewpoints, with Artificial Intelligence and Deep Learning.

S06. Stay connected: Developing Mobile GIS for team-based collaboration in archaeological research

Julia M. Chyla, University of Warsaw. Faculty of Archaeology
SOBOTKOVA, Adéla, Aarhus University, School of Culture and Society,
BUŁAWKA, Nazarij, Landscape Archaeology Research Group (GIAP), Catalan Institute of Classical Archaeology
CIRIGLIANO, Giuseppe Prospero, University of Siena, Department of History and Cultural Heritage

Session type: other (10-15 min papers + moderated discussion afterwards)

Mobile GIS Special Interest Group has in its previous CAA conference editions (2017, 2018, 2019, 2021) drawn attention to the importance of mobile GIS in archaeological and other field research, specifically its impact and contribution to fieldwork methodology and data collection (Buławka and Chyla, 2020; Sobotkova et al., 2021). In this edition, we survey how the use of mobile GIS in archaeology has progressed in recent years. In the early phase of COVID pandemic, Scerri et al. argued that sciences working in the field, including archaeology, had to change their ways (2021). The review of the recently published literature partly confirms it. As most international expeditions were canceled, scholars working in the field had to stop their projects. Many projects abandoned field work in favor of office work, for example remote sensing and data analysis. Others, in the late phase of the pandemic, found their way to continue working by novel methods of collaboration (Geser 2021; Magnani et al. 2021; Matte and Ulm 2021). COVID demonstrated the benefit of producing FAIR digital data in the field. Robust toolkit ensured that the collected data were born-digital, complete and consistent upon departure from fieldwork. Having all data shared and accessible by all team-members afterwards meant that work could continue remotely, which was a source of relief during the lockdown (Sobotkova et al., 2021). Additionally, we would like to explore the current differences in collaborative solutions between open-source and commercial software. Do the different OS and commercial software entail a different organization of archaeological fieldwork? What aspects and reasons lead a research team to choose an OS versus a commercial software? What is the range of funding models used to develop or deploy different mobile data capture applications? How should archaeologists prepare for OS updates, changes in hardware compatibility or application funding models so as to retain the ability to use the same workflow in the future? Another aspect that we would like to address at CAA 2023 is the capability to produce standardized results that follow good practice using mobile GIS nowadays. Some archaeologists report increased fieldwork efficiency thanks to the use of mobile devices (Austin 2014; Ames et al. 2020) while others focus on the downsides of the digital medium, such as deskilling, (Caraher 2016; Gordon et al. 2016), or stress the need to manage workplace change and fine-tune daily operation under the new circumstances (Vanvalkenburgh 2018). What makes the difference? Have the mobile devices transformed the entire lifecycle of archaeological research from team-based field data capture to analysis, sharing, and publishing, or affected only the day-to-day working processes in the field? And more specifically: is mobile GIS essential for digital fieldwork? If so, what are the must-have features of mobile GIS and how do you prioritize them? The session invites papers that may concern methodological and technical aspects and will be finished with a moderated discussion.

S07. Open Analytical Workflows and Quantitative Data Integration in Archaeological Prospection

Session type: Standard

This session invites contributions from the field of prospective archaeology that address the design of open, reproducible, and transferable workflows for archaeological and environmental data processing, analysis and interpretation and/or quantitative data integration across different sensors, modalities and scales for the study or archaeological landscapes.

In recent years, archaeological prospection has benefited enormously from the increasing quantity, quality and availability of digital data from remote sensing and geophysics that record selected environmental parameters across space, often at high resolution. This wealth of data now allows archaeologists to go beyond the traditional remit of archaeological prospection, namely the detection and mapping of traces of past human activity, and to study landscapes and the ecological and anthropogenic processes that formed them over time from a holistic perspective.

However, the full potential of this approach is often not realized in the practice of archaeological research and heritage management due to a limited availability of skills, tools and protocols. Many projects focus on specific data types or analytical methods, without making use of additional sources of information that would also be available and might be able to add important interpretative dimensions. Often, the choice of data and methods is motivated by practical constraints rather than analytical potential. Also, the joint analysis of remote sensing or geophysics data and data from field observations (e.g., surface survey, corings, excavations) is often performed on a qualitative level only, due to a lack of suitable protocols for a combined quantitative analysis.

Another common problem is that many projects create ad hoc solutions for their analytical and interpretative workflow that are not easily reproducible or transferable to other projects. There is still a lack of open, standardized protocols and workflows that can be applied to a variety of cases, even though promising approaches exist (e.g., Lozić & Štular 2021). Further inspiration may be drawn from other domains that often use the same environmental data, e.g. ecology, geomorphology or soil science. Here, the development of open analytical and interpretative workflows that allow the integration and joint quantitative analysis and interpretation of data from remote sensing and field observations is further advanced than in archaeology (see, for instance, Ghamisi et al. 2019; Chatterjee et at. 2021).

In this session, we welcome papers that showcase and evaluate novel approaches to analytical workflows and data integration in archaeological prospection. Alongside case-studies that offer concrete examples of these issues in archaeology and presentations of workflows and theoretical frameworks, we encourage contributions on best practices in associated fields and their relevance for archaeological applications.

S08. Where do you draw your lines? Mapping transformation of archaeological practice in the digital age

Nicolò Dell’Unto, Lund University
James Stuart Taylor, University of York

Session type: Standard

Archaeology has always had a close relationship with emerging digital technologies, and the last ten years have seen a dramatic uptick in the application of these technologies across the discipline (‘The Digital Turn?’). From the refinement of database management systems, ontologies, and the principles that guide them (F.A.I.R.), to experimentation with computational approaches like Network Analysis and Agent Based Modelling, to the almost universal adoption of spatial technologies and the current golden age of 3D data acquisition and VR. From our perspective, the impact upon our fieldwork has been profound. The question of where you draw your lines has a literal gravitas these days (on paper, in a GIS, in your simulation, or straight into your 3D environment?). But what about the discipline more broadly? We have recently argued that digital practice that consumes emergent technologies often emulates an analogue counterpart as a skeuomorph of practice, as part of a process of testing the affordances and limitations of new technologies. In doing so, these technologies are socialised as we become comfortable with them, so that we can ultimately use them to transform our practice (Taylor & Dell’Unto 2021). Increasingly these transformations may be more fluid, with archaeologists potentially shifting their practice from analogue to digital, digital to digital, and even digital to analogue. In this session, we would like to explore these transformations, no matter how great or small; where do you draw the line? [~your lines?]. How has your archaeological practice been affected by new and emergent technologies? In the field? In the lab? In the museum? And across the years? We invite you to literally map or diagram these transformations, reflect upon them in the example of your own practice and together, perhaps we will explore emerging digital trends and future disciplinary directions. Session Structure This will be a standard session focused upon a series of 20-minute papers in which we literally encourage you to ‘map’, ‘chart’ or visualise your transformative practice. We encourage collaborative papers that include or foreground the work of junior researchers. The last part of the session will be set aside for a round table discussion of some of the themes that emerge throughout the day.

S09. Digital approaches to Roman port urbanism: from data acquisition to computational analysis and visual reconstruction

Session type: Standard

Under the Roman Empire, ports were nodal points, significant hubs of economic – and cultural – interaction and movement, where ships, people and goods both departed and arrived. The ports’ urban infrastructure and organization facilitated smooth import and export of goods and, as such, ensured connectivity in the entire network. We can, therefore, say that ports were the heart and motor of maritime exchange networks.

While studying the interaction between these nodal points (often represented as dots on a map) remains of high importance – to detect patterns of trade/connectivity and evaluate organizational aspects related to maritime trade – we want to shift the focus in this session to the dots themselves: the ports. Although the study of port environments has increased substantially in the last few years due to the development of disciplines such as underwater and maritime archaeology, the topic of port urbanism – addressing the port’s unique urban fabric, its structure and infrastructure – often remains underexplored. This session aims to examine both the port’s configuration towards the sea and its urbanization away from the sea through digital and computational methodologies.

The port’s urban arrangement on the waterfront – thus the purely functional infrastructure and facilities – guaranteed (long distance) trade and the logistical aspects of loading and unloading of goods, as well as their control (quality and weight) and storage. But ports were not only transit hubs, ‘dots’ of arrival and departure, they were places of residence, places of vibrant urban and cultural life developing away from the seafront. The merging of these two types of urbanism ensured that ports formed a real urban landscape ‘with enough features of complete towns to give it an acceptably urban aspect’ (MacDonald 1988, 262).

In this session, we want to evaluate how digital and computational approaches and methods can be used to reach new perspectives on the urbanism of Roman ports. We aim to approach this topic from a variety of angles, with papers (20 min + 10 min discussion) particularly – but not exclusively – addressing the following main questions:

  • How did ports facilitate movement/interaction of people and goods within the port itself?
  • How was the urbanization towards and away from the sea connected and how did this evolve? In other words, how was the city and its port connected?
  • How did the port’s urban texture impact maritime activities, and vice versa, how did these activities influence the urban structure of the port?
  • How did the urban organization of ports facilitate and ensure maritime trade connections?

We invite submissions of different applicative digital approaches for modeling or simulating Roman port cities whose results come from either invasive (excavations) or non-invasive research (drone, aerial or geophysical surveys). Possible topics include but are not limited to applications or discussions of the following approaches:

  • Topographic modeling
  • GIS modeling and simulations
  • Computational analysis of spatial configuration of port cities, through for instance urban network analysis, space syntax analysis, etc.
  • 3D reconstruction methods
  • Cultural mediation tools like AR and VR

S10. Computer applications in archaeology – Bringing South Asia together

Session type: Standard

South Asia (SA) is one of the archaeologically and historically rich geographies in the world. Though archaeology as a domain was initiated and had its founding years during the colonial period, the explorations, excavations, and material studies have reached new heights since then. Being the home of the Buddhist era, Harappan civilisation and several prehistoric phases, SA has brought forward interesting materials for analysis that are closely associated with (i)presence of hominins, (ii)early hunting-gathering communities, (iii)early domestication of plants and animals to (i)social systems, (ii)dynastic rules, (iii)urbanisation, (iv) diverse yet contemporary language and cultural systems and many more which assist in better understanding of multiple aspects of human past in this part of the globe.

In recent decades, the advent of technology and computer applications has touched almost all aspects of life, and archaeology is not an exception at all. In SA, many examples of employing these technologies can be seen: geospatial technologies and GPR surveys to name examples. Analysing quantitative data for ceramics, stone-tools, coins, etc is another discourse as well as 3D modelling of monuments and artefacts for academic studies, museum displays and public education. Furthermore, the use of agent-based modeling to simulate prehistoric environments and human behaviour can be used to shed light on early mobility patterns and socio-cultural systems.

What is interesting in SA, especially India, is that many of these listed examples continue to remain as examples or case-studies but are yet to become main-stream practice or part of the curriculum. Likewise, basic technologies for storing data in structured databases, documenting surveys or explorations using appropriate coordinate systems and formats is yet to become standardised in SA archaeology. It is currently taught, studied, and perceived mostly as a humanities and social science (HSS) subject and has not yet been fully explored for computational research.

Computer applications (CA) help bring data together from several domains, transform it, visualise it and analyse in ways which are otherwise humanly impossible. Recognising its value, ensuring academic training, and implementing standard practices is the need of the time in Indian archaeology. CA should not be seen as one of the outcomes or characteristics of processual archaeology but rather a starting point for pursuing any theoretical approach.

This session aims to bring together scholars from SA who have innovative ways of employing CAs at any stage of archaeological research work. We invite talk abstracts from enthusiastic scholars from diverse academic backgrounds wishing to take archaeological research in SA to the next level by applying computational and theoretical tools to shed light on the rich history of SA. Those who wish to present their ideas for tackling specific problems such as academic divide, lack of training, research bias, budgetary constraints, and historical baggage (to name a few examples) are also more than welcome to submit abstracts.

S11. The Age of #Archaeogaming: The Past and Future of Archaeology + Video Games

Aris Politopoulos, Leiden University & VALUE Foundation
Sebastian Hageneuer, University of Cologne
Csilla E. Ariese, VALUE Foundation & Reinwardt Academy

Session type: Standard

The last decade has seen the exciting development of a new field in digital archaeology: archaeology and video games. The field, commonly known as archaeogaming, deals with such concepts as the use of video games for archaeological research, the archaeological study of video games, and the implementation of video games for heritage and outreach. Popularised initially on social media and in blogs, #Archaeogaming has brought together researchers from diverse disciplinary backgrounds. In this session we will celebrate the origins of the field, consider its current inter- and intra-disciplinary synergies, and dream together to envision its futures. ORIGINS The engagement of archaeologists with video games has no singular point of origin, neither in time nor in place. Although archaeologists have used computer applications for half a century, and the first historical video game dates to the era of the earliest computer games, Archaeogaming as a field of study is significantly younger. The first publications on the topic appeared in the 2000s, dealing with a variety of topics, from exploratory (Gardner 2007), to experimental (Morgan 2009), to heritage (Champion 2011). It was in the early 2010s however, when the term ‘archaeogaming’ was coined, after the namesake blog by Andrew Reinhard, and the field started taking shape. The origins of the field were characterised by a great freedom of exploration. In part, this was due to the fact that the new area of study had no set boundaries, nor any clear research agenda (Mol et al. 2021). Additionally, significant research was carried out outside of formal academic settings, by researchers in their own free time or at least on the side lines of grant projects. This freedom enabled a wide-spread exploration of all aspects and angles of Archaeogaming and also drew people from different disciplines and, notably, many early career scientists. Entering #Archaeogaming’s second decade, we are ready to reflect on our origins. What qualities characterise the field and set it apart from other research strands in computational archaeology? Which milestones, perhaps outside the Anglophone, should be included in its origin story? We welcome any papers that delve into the (brief as it may be) history of #Archaeogaming. INTER-/INTRA- DISCIPLINARY SYNERGIES Over the years, the field’s popularity has drawn increasingly more participants, especially appealing to those whose gaming at home has taken on extra meaning. With openness and innovation at its core, there seems to be no end to the themes and potential avenues for research. Archaeogaming studies have included a wide variety of topics like decolonizing and ethical movements, collaborative digital survey projects, and game making experiments. The fluidity of the field has allowed for a richness of synergies that fearlessly cross disciplinary and sub-disciplinary boundaries. Despite archaeogaming’s growth and the enthusiasm of its participants, the field has struggled to gain a secure foothold in academia. With play as a core component of its practice, archaeogaming has often been disregarded as frivolous or non-serious. While universities have been quick to showcase archaeogaming endeavours to attract new students, they have been slow to formalise archaeogaming in terms of funding, teaching positions, or long-term support. As a result, archaeogaming projects have mostly been incidental and there is a lack of sustainability. Conferences and an exponential increase in academic publications have helped to formalise archaeogaming as a ‘real’ or ‘legitimate’ strand of research, but this struggle for understanding has taken time and effort away from further expanding the field. Where does archaeogaming stand at the beginning of its second decade? What is the actuality of its practice – and is this what the field should indeed be focusing on? We welcome papers that reflect on the current state of the field of Archaeogaming and any areas that remain un- or under-explored. We also welcome presentations about ongoing or recent Archaeogaming projects, particularly those discussing current methods and practices. ENVISIONING THE FUTURE Although not a completely blank slate anymore, the future of archaeogaming is still malleable and open. From our perspective, we expect three major influences on how this future will take shape. Fundamentally, the future of video games and the video game industry, including technological developments such as AR and VR, will significantly impact the source materials that we can work and play with. Secondly, we anticipate that established and new scholars will build upon previous research: celebrating past achievements while also correcting our course to compensate for omissions, gaps, and weaknesses. Finally, Archaeogaming’s future will also be dependent on structural and institutional support both from within academia as well as the game development industry. In this session we would like to welcome all archaeogaming scholars, enthusiasts, or people curious about the field to envision its future together. We are curious to hear about new avenues to explore, but equally interested in how tried and tested methods can be applied to future games. Please share your dreams or future realities. PAST AND FUTURE This session is both about celebrating archaeogaming’s origins and about envisioning the exciting opportunities that lie ahead. We welcome students and scholars whether you are new to the field or have been following and contributing over the years. We welcome traditional paper presentations as well as playful projects and game demonstrations.

Time and its analysis are at the heart of archaeology: one of the main objectives of the archaeologist is the establishment of a temporal framework for a given layer, site or material culture. But archaeology covers such a wide range of cultures, dispersed both in time and space, that contextual chronological assessments are constructed using very different tools, languages and techniques. It creates as many different temporal and cultural frameworks as there are specialties, with notable differences in approaches depending on whether one is dealing with absolute or relative chronology, laboratory techniques or cultural approaches, deterministic or statistical methods (Buck and Millard 2004). The aim of this session is to explore a wide variety of research tools and techniques related to (semantic) chronological modelling in archaeology in order to identify common methodological frameworks and to build bridges between specialties. This also invites approaches from CAA Special Interest Groups (SIG), e.g. on Scientific Scripting Languages in Archaeology (SSLA) and Semantics and LOUD in Archaeology (Data Dragon) as well as from the CAA Little Minions on chronological modelling. These SIGs are following the FAIR (Bahin et al. 2020) and FAIR4RS (Hong et al. 2022) principles in the idea of Open Science, including Open Access, Open (Research) Data and Open Source (Research) Software.

We invite papers in all fields related to time/chronology research, including:

Bayesian modelling. Bayesian modelling has revolutionized the way radiocarbon dating is practised nowadays (Buck et al. 1991; Bronk Ramsey 2009). The introduction of known priors (e.g., stratigraphic sequences, termini post/ante quem) into the radiocarbon calibration process enables researchers to obtain much more precise dating intervals than previously, when radiocarbon samples were individually calibrated rather than incorporated into a model. Many software tools are currently available for Bayesian modelling in archaeology, such as OxCal, BCal, ChronoModel, as well as R and Python packages. 

Stratigraphic modelling. The most famous tool for stratigraphic modelling is the Harris matrix (Harris 1989), which has been the focus of much software development (Harris Matrix Composer, Stratify, Stratifiant, …). Originally designed as a tool restricted to relative chronology, the Harris matrix has also seen developments aimed at extending this formalism to include absolute dating elements (see for example Desachy 2016). Similar efforts have extended the model’s power to be able to automatically detect temporal relations between stratigraphic units (see for example the Phaser tool). 

Temporal logics. Temporal logics is an important field of mathematical and computer science research (Demri et al. 2016), which has up to now found too little applications in archaeological research, probably due to a lack of communication between the relevant research communities. The main results of temporal logics widely applied and cited by archaeologists (see for example Holst 2004; May 2020) are the fundamental, but old, Allen relations (Allen 1984, 1991). The archaeological research community has otherwise only brought too little attention to recent research results in temporal logics. 

Seriation techniques. A classical way to provide relative chronology between artifacts, even in the absence of stratigraphic information, is seriation (O’Brien and Lyman 1999). In its variant called frequency seriation, the relative frequencies of each type of artifacts found within the same layer are computed and presented in chart form. The relative order between these layers (possibly coming from different sites, thus not featuring a relative stratigraphic order with each other) can then be established using the hypothesis of unimodality of artifact production. Seriation is an old but powerful method, which seems to have fallen out of fashion in many fields of Old World archaeology, but that still saw significant advances in the last decades (see for example Lipo, Madsen and Dunnell 2015). 

Chronological networks. Until recently, little attention had been brought to the application of deterministic (i.e. non-statistical) techniques to building wide regional chronologies, based on historical data and cultural synchronisms. The goal of such techniques is to automate the archaeological cross-dating process by encoding a network of chronological relationships between temporal entities, and using algorithms to build the global chronology by propagating along the network a set of absolute dates located at specific nodes of the network. This approach has recently been implemented by two software tools: Groundhog (Falk 2016, 2017, 2020) and ChronoLog (Levy et al. 2021a, 2021b), relying on different techniques (exhaustive search and graph-theoretic techniques, respectively). 

Linked Open Time Data (LOTD). Chronological Linked Open Data provides chronological space-time-gazetteers, e.g. PeriodO, GODOT and ChronOntology, and standard formats and ontologies, e.g. RDF, OWL TIME, EDTF, and CIDOC CRM, Alligator Ontology, AMT Time Ontology. LOTD and open source research tools allow for reproducible research, the unveiling of “hidden assumptions” in archaeological data and the semantic modelling of fuzziness and wobbliness. An example could be statistical approaches such as the horseshoe paradigm using correspondence analysis and the application of temporal logics to do temporal reasoning (Madsen 1998; Thiery and Mees 2018).

Other approaches. A host of other formal approaches to chronological modelling and computation have been explored in the recent years, such as fuzzy logics (Niccolucci and Hermon 2015), aoristic analysis (Crema 2012), and evidence density estimation (Demján and Dreslerová 2016). 

We welcome papers dealing with new theoretical, methodological and research software developments in any of the above fields, in order to promote shared practices and the discovery of new ideas and paradigms.

S13. An inventory of the Sea: our shared marine heritage challenges and opportunities

Peter McKeague, Historic Environment Scotland
Professor Julian Richards, Archaeology Data Service, University of York
Dr Clare Postlethwaite, MEDIN Coordinator, National Oceanography Centre

The marine environment is a vast resource, covering over 70% of the Earth’s surface. Our seas provide an exceptional record of human activity from the seabed to the shore; from iconic wrecks through submerged landscapes and inter-tidal archaeology to the ports and harbours providing the onshore infrastructure supporting fishing and trade. Despite the richness of our marine heritage, accessing, re-using and presenting information about that heritage can be challenging – much more so than for terrestrial archaeology. Marine data are expensive to collect but have considerable reuse potential to increase our knowledge. The multi-disciplinary character of marine data, including commercially or scientifically sensitive data, pose particular challenges to ensuring that data conform to the FAIR Data principles ( Of course, there is a large international dimension to marine and maritime data, with trading connections, ships logs and manifests adding rich detail to our understanding of maritime traffic. Our marine heritage is more than ships and wrecks. Intertidal archaeology offers opportunities for public engagement and citizen science but is particularly at threat from coastal erosion and climate change. Offshore infrastructure projects offer the opportunity for multidisciplinary research into submerged landscapes. The opportunities for new discoveries on the seabed have increased significantly through large scale seabed remote sensing data undertaken for the offshore renewables industry and national mapping. Application of machine learning and artificial intelligence to these massive survey datasets can assess seabed survey data to identify potential wreck sites and other obstructions. In the United Kingdom some of the challenges presented in working with the historic marine environment are being addressed in the Towards a National Collection funded ‘Unpath’d Waters’: Marine and Maritime Collections in the UK ( By developing data standards, including key controlled vocabularies, and cataloguing practices Unpath’d Waters aims to improve interoperability across national heritage agency resources and unlock opportunities to work more closely with museums and archives. This session will explore:

• Solutions to harmonising marine data from across the heritage sector with the broader marine data landscape, in ways that enhance their Findability, Accessibility. Interoperability and Reusability.
• Visualisations and simulations that promote our understanding of submerged landscapes and wrecks.
• Applications of artificial intelligence and machine learning to explore marine heritage data and paleaolandscapes.

Whilst not an unknown frontier, our marine past is an underexplored frontier providing significant opportunities to apply a range of computer applications to improve the quality of the archaeological record. This session will explore how computer applications can be applied to the broad range of marine datasets to improve our knowledge and understanding of our maritime heritage and to communicate a difficult to access environment more broadly through novel techniques.

S14. Robotics and Archaeology – on the state of the art and beyond

Daniel Carvalho, UNIARQ; FCT; LAQU

Session type: Standard

Robots are an integral part of contemporary society. From healthcare to manufacture, agriculture and industrial contexts, robots play fundamental roles, indispensable to maintaining and sustaining numerous systems. Archaeology, as well as various areas, utilizes robots in its endeavors: on the field, in laboratories, in presentations to the public. From automatic typologies to UAVs that reach the depths that humans can not fathom to venture, robots aid archaeologists in concluding their tasks, in an efficient and reliable way. Is it possible to go even further and elevate the role of robots within Archaeology? Are robots to be used as extensions and tools or can we conjoin them with Artificial Intelligence, and build an Artificial Archaeologist? In this session, we intend to discuss the present state of robotics in Archaeology and dwell on the possibilities that lie in the near future. Proposals, although not exclusive, would be very welcome on these lines of thought, both concerning eventual case studies and theoretical reflections: How do archaeologists use robots, in which circumstances and what are their benefits and drawbacks; Robots and the act of the excavation – should robots do fieldwork for us? How archaeologists can use robots for building knowledge and how would it affect the discipline; What should be the ethical concerns that surround the use of robots in Archaeology?

We encourage papers from students and ECR in different phases of their research, to provide a space for showing their ongoing work and progress.

S15. Reproducing, Reusing, and Revising Code and Data in Archaeology

James R. Allison, Brigham Young University
Sophie C. Schmidt Berlin Graduate School of Ancient Studies, Freie Universität Berlin
Florian Thiery M.Sc., Römisch-Germanisches Zentralmuseum, Department of Scientific Computing and Research Software Engineering, Mainz, Germany

This session aims at evaluating how reproducible research in archaeology is actually faring. It has been argued that reproducible research techniques such as publishing and sharing code as well as data speed up scientific progress (Marwick 2017, Schmidt & Marwick 2020). With the FAIR movement and the rise of (Linked) Open Data approaches there seem to be more and more archaeological data sets available. Code used for archaeological analysis is also increasingly published online. There are a growing number of openly available code examples that have been used for articles (see for R, or for Netlogo ). In some cases, this shared code may be adapted into “little helpers”, small modules of research software, aka Little Minions (Thiery et al. 2021), that can be reused and individually adapted. The community of Research Software Engineers (RSE), people who create software applications for research, is growing. For better dissemination of these programs, they created the FAIR4RS principles (Hong et al. 2022). RSEs are fighting for scientific recognition by e.g. implementing the CFF format to cite software (Anzt et al. 2020). But despite this general progress, published articles reusing or adapting open data or code are rare in archaeology. It is difficult to assess how often code and data are reused for research, but the rate of reuse appears to be low (Huggett 2018, Marwick and Birch 2018). Open data and code may be reused more often for teaching (Cook et al. 2018, Gartski 2022, Marwick et al. 2019), but it is not clear how often this happens. In this session we would like to ask the following questions

• How often does it happen that archaeologists try to reproduce each others’ analysis, or borrow code from each other?
• Can fruitful examples be shown?
• Are there examples of replication or reproduction of analyses failing?
• Which techniques are needed to successfully reuse data and code from other persons – on the side of the provider as well as the reuser (forking, data papers, …) ?
• Are these methods taught to students and how are they taught?
• What reproducibility techniques should be focused on in the future?
• What problems arise in trying to re-use data (not just tabular, but also eg 3D and geophysical data)

By discussing these topics we want to encourage the re-use of openly available data sets and published code in archaeology. We particularly welcome papers that reuse or adapt openly available code to analyze new datasets, or papers that reanalyze existing open data in new ways. We would very much like to see contributions that generate open code to replicate previous analyses or create newly open data sets from existing data that is currently difficult to access (e.g., data found only in printed tables in reports or articles). Papers that examine the use of open data and code in teaching are also very welcome. We hope to fuel a debate about the usefulness and worthwhileness of creating open data and code. Reproducibility needs to be evaluated not just from a theoretical viewpoint but also in practice.

S16. Archiving information on archaeological practices and knowledge work in the digital environment: workflows, paradata and beyond

Isto Huvila, Uppsala University
Jessica Kaiser, Uppsala University

Session type: Standard

Knowledge of archaeological work – from fieldwork and post-excavation and laboratory analyses to visualisation and beyond – is crucial for understanding and using its different outputs independently if they are digital or non-digital data, reports, or monographs, digital visualisations, or models. There is a growing corpus of empirical and theoretical research and accounts of practical work on documenting, capturing and keeping information pertaining to archaeological, scientific and scholarly practices. These studies range from the documentation of traces (e.g. Morgan & Eve, 2012), paradata (e.g. Gant & Reilly, 2017; Denard, 2012; Huvila et al. 2021) and, for example, provenance metadata (e.g. Huggett, 2014) and how information can be preserved as a part of the archaeological record. This session invites presentations of evidence-based, theoretical and reflective work relating to archiving of information that describes and documents digital archaeological practices. The session is open to quantitative and qualitative evidence-based studies of archiving and re-use of archived information on archaeological practices and knowledge work, as well as theoretical work shedding light on different, for example, epistemological aspects of the topic. Further, the session welcomes reflections and descriptions of how such information has been archived or is planned to be archived in practice. Relevant contexts for presentations discussing archiving and the implications of different types of information archived on archaeological practices and knowledge work in the digital environment range from archiving and preserving fieldwork, to the documentation of data creation (for example, database design and management), working on legacy documentation, metadata and paradata, automatic and manual archiving and beyond. Proposals are welcome from the entire CAA community including archaeologists, social and computer scientists, heritage, museum and information studies researchers and practitioners. The format of the session (Standard session) consists of paper presentations and discussion, including a concluding open forum for sharing and collecting ideas for future research on and in relation to traces of digital archaeological practices. The session is affiliated with the CAASIG ARKWORK on archaeological practises and knowledge work in the digital environment.

S18. Modelling Ancient Cities: methods, theories and tools

Katherine Crawford, The Cyprus Institute

Dries Daems (Middle East Technical University, Turkey)

Session type: Standard

The city has been a major topic of interest for archaeologists from the early days of the discipline until now (Woolf 2020; Childe 1950). In recent years, scholars have increasingly come to see cities as inherently complex systems requiring a wide range of tools and specialist methods to study their functioning, evolution and transformations (Batty 2007; Shi et al. 2021; Ortman, Lobo, and Smith 2020). The application of quantitative methods for the study of ancient cities and settlement networks has likewise seen increased interest in recent years (Lobo et al. 2019; Ortman et al. 2014). Increased accessibility to large scale datasets, due to advancements in data collection, has resulted in an increasingly diverse number of studies looking at past cities from new perspectives, focusing both on their idiosyncrasies and cross-cultural comparative dimensions (Smith 2020; Baumanova and Vis 2019). At the same time, recent developments in excavation, recording and analysis techniques have enabled archaeologists to dive deep into the past of individual cities, reconstructing their built environment (Fletcher 2020), infrastructure (Crouch 1993), social-economic interactions (Smith et al. 2014) or even their inhabitant’s diets (Rowan 2017). These advancements in methods, data and theory have opened new possibilities for the study of cities and settlement systems at different scales.

This session invites papers that deal with the applications of computational and digital methods, grounded in population-level systemic thinking, but also coming from the individual perspective, that investigate the structural properties and mechanisms driving complex socio-natural urban systems. The goal is to showcase the potential of using systematically collected data on urban systems and formal analytical methods to broaden our understanding of the general mechanisms driving urban dynamics. These may include but are not limited to: agent-based modelling, network analysis, urban scaling, gravity and spatial interaction models, space syntax, GIS, and data mining applied to such topics as settlement persistence, urban social complexity, multi-scale spatial patterns within urban complexes and across settlements, inter and intra- settlement dynamics, urban-environmental processes, and city historical trajectories including urban formation and abandonment.

We look for a diverse range of studies on the interactions between cities, simulations of social and socio-natural activities, as well as analyses of groups of cities and their environment. We are especially interested in papers that adopt a large-scale comparative and diachronic perspective to studying transformations and transitions of urban and settlement systems.

S19. Building a Collaborative & Interoperable Information Ecosystem: A conversation to bridge archaeological data systems and infrastructures

Annabel Lee, Enriquez Getty Conservation Institute
Alison Dalgity, Getty Conservation Institute
David Myers, Getty Conservation Institute

Session type: Round table

The session will explore ways to foster a richer and more collaborative information ecosystem in archaeology. This landscape encompasses commercial information services and software applications, academic and nonprofit information services, and multiple open-source projects. Some of these information systems are general purpose, and some are specifically designed to meet unique information management needs in archaeology and cultural heritage.

For example, the Arches project develops open-source software to support cultural heritage data management needs and has built a strong community of organizations and people who actively use the application worldwide to document and conserve cultural heritage, including numerous implementations dealing with archaeological recording, risk assessment, and research. The project’s goal is to ensure improved data management to support effective heritage conservation and management, and ultimately to improve understanding and stewardship of cultural heritage resources by providing researchers with tools for creating, sharing, and exploring data.

But Arches is only one of a constellation of software systems and services used in archaeology. Cultural heritage professionals have many and diverse information needs that extend beyond areas that Arches currently supports. KoboToolBox, FAIMS, and others provide field data collection tools, while Pelagios offers a number of software applications and online services that help researchers use and create Linked Open Data. Besides these tools, other online data systems, including various gazetteers and collections databases, as well as digital repositories play critical roles.

The success and vibrancy of archaeological information systems depends upon a collaborative community that builds upon each other’s contributions. We are hosting a round table session including key panelists and an open discussion to explore how this diversity of applications and services can better work in concert. Questions to be explored include:

·      Where might there be areas of complementarity that can be further developed? 

·      Can we promote workable more modular design practices so we can develop and share useful components across different projects? Would this help address “not invented here” disincentives to build upon each other’s efforts? 

·      What roadblocks may exist in establishing greater interoperability?           

·      What opportunities can be explored for collaborative partnerships? 

·      What lessons can we learn from one another? And, how can we collaborate and leverage the strengths and roles of each system to better serve archeological management and research, and cultural heritage in general?

S20. Simulations for the past, simulations for the future

Isaac Ullah, San Diego State University
Iza Romanowska, Aarhus University
Doug Rocks-MacQueen, Landward Research

Session type: Standard

Simulation is the closest tool we have to a time machine. It enables us to investigate past complex social and socio-natural dynamics in a robust scientific manner that overcomes some of the limitations of the archaeological record. This year marks the tenth anniversary of the regular “ABM session” at the CAA conference. In the last decade, over 50 researchers from all continents presented their models ranging in spatio-temporal scope from the earliest hominins’ global dispersal to reconstructions of particular building projects in historical times. We have tested hypotheses regarding the origins of cognition, language and art, assessed subsistence strategies of groups across virtually every Earth’s biome, looked for mechanisms driving complex human interactions such as exchange, demographics, or warfare and tried to determine what processes shaped human mobility and settlement distributions over various types of landscape or preference for particular products. However, simulation studies also opened up archaeology to bigger and more general research questions that transect the particularities of any one case study. While most models focus on a low-level research question –what has happened in a particular place at a particular time – they also give us insight into general tropes of human behaviour, interactions and response to change. These topics have been of much interest in archaeology since the earliest days, but they are more often simply discussed rather than operationalised, developed, and tested within formal, scientific frameworks. The objective of this session is therefore twofold. First, to showcase the breadth and contribution of archaeological simulation to our understanding of the past and past people. Second, to reflect on the contributions that our models make or could make in the future to addressing the grand societal challenges currently faced by humanity. We invite papers that describe research involving formal simulation modelling methods, such as system dynamics, agent-based modelling, cellular automata, etc., on any topic without restrictions regarding the scope, subject, spatial or temporal aspect, or level of completeness of the model. We ask the authors to dedicate one slide of the presentation to the question of whether and how their model could contribute to one of the UN-defined Global Goals (

S21. 50 Years of Archaeological Simulation

Iza Romanowska, Aarhus Institute of Advanced Studies

Session type: Round table

Archaeological simulation has long roots in archaeology, comparable to other disciplines, however, its later historical trajectory differs significantly. From the optimistic beginnings, through the “dark ages” of the 1980s and the new dawn triggered by the rise of complexity science and simple modelling frameworks such as NetLogo in the 1990s and early 2000s – simulating the past had a rich but choppy history. As its popularity changed, so did the archaeologists’ perception of its role in archaeological discourse as well as topics and types of research questions tackled through modelling. Similarly, the scope and type of simulations developed by archaeologists changed over time, from the early “whole-world” equation-based system models of the 1960s to the sleek and elegant simple abstract ABMs of the early 2000s and much more complex ones in the last decade. Being a small community individual archaeological modellers played a large role in the shaping of the discipline and their particular interests, specialisms and characters had a much stronger impact than would be expected in a larger research field. The 50 anniversary of the CAA is a fantastic opportunity to critically reflect on the development of archaeological simulation. Thus, the aim of this roundtable is to look back at the history of archaeological simulation, the scholars, topics, tools and models developed in the last 50 years. Taking stock of where we stand now, we will discuss the key challenges, growth areas and actions needed to sustain the steady growth of archaeological simulation. This will hopefully allow us to sketch out the possible futures of archaeological simulation modelling. A draft overview paper will be circulated a month before the roundtable and then discussed by the panellists and the audience. The paper will be then opened to all participants so that it can be written and edited in a truly collaborative fashion. The goal is to represent the multivocality of archaeological simulation modellers across generations, theoretical traditions, different simulation methods (EBM, ABM, CA), or modelled topics. With all contributors listed as authors, we will submit the paper to the special issue of the Journal of Computer Applications in Archaeology to be considered as part of the special issue celebrating the 50 years of the CAA.

S22. Machine and deep learning methods in archaeological research – creating an integrated community of practitioners

Alex Brandsen, Leiden University
Wouter Verschoof-van der Vaart, Leiden University
Daniella Vos, University of Groningen
Daniël Paul van Helden, University of Leicester

Session type: Standard

We are witnessing an increase of papers, sessions and discussion on Machine Learning (ML) and Deep Learning, both within CAA and outside of the conference, and it is apparent that there is plenty of interest in the application of these methods in archaeology [1]. This interest might be partly ascribed to advances made in Deep Learning – in particular Convolution Neural Networks – across various disciplines. Applications using these methods now show high performance and in some cases exceed humans on challenging tasks ranging from computer vision to natural language processing. In digital archaeology we have seen and foresee applications of these techniques including automated object detection in remote sensing data, artefact image classification, use-wear analysis, text mining, paleography, predictive modelling, 3D shape analysis and recognition, and typology development.

The diversity of AI-based procedures, methods and archaeological applications results in a certain lack of standardised approaches, comparable accuracy metrics, and reusable workflows, leading to a “reproducibility crisis” [2]. If we want to learn from each other, avoid common pitfalls, and together push this topic forwards within archaeology, we need to move beyond isolated case studies, and look into how we can best combine our efforts.

This session aims to: 1) offer a space for comparing methods, algorithms, code, APIs and workflows; 2) discuss the problems related to their application and; 3) offer insights into best practices including sources of error and validation methods. The ultimate aim is that the combination of approaches and the ensuing discussion will help to further build an integrated community of practitioners.

We specifically invite authors to submit papers relating to the creation of (annotated) datasets & the sharing of developed methods, data (or data structures) and code, but also welcome papers on the more broad subject of Machine Learning, relating to the following themes:

  • Using small, incomplete and noisy datasets for ML;
  • Choosing and tuning specific ML techniques;
  • Evaluation of ML and conventions for performance metrics;
  • Interpretation and validation of ML results;
  • Collaboration and insights from ML fields outside of archaeology;
  • Ethics of ML in archaeology;
  • Education of ML in archaeology;
  • Case studies on the application of ML to the analysis of texts, artistic representations, bioarchaeological remains, material culture, archaeological sites, etc. Combinations of such approaches will be particularly welcome.

For practical approaches we would encourage a critical dialogue to identify individual and shared problems, opportunities, and solutions. We invite authors to provide a thorough explanation and evaluation on their methods.

S23. Understanding Archaeological Site Topography: 3D Archaeology of Archaeology

Gert Jan Van Wijngaarden, University Of Amsterdam

Session type: Round table

The current ubiquitous use of 3D recording technologies in archaeological fieldwork, for a large part due to the application of budget-friendly (drone) photogrammetry, has exponentially increased the availability of 3D data of archaeological sites and landscapes. Various applications, such as 3D excavation documentation, prospection, heritage management and of course visualisation/presentation have already advanced beyond the experimental phase. In this round table, we would like to discuss the application of 3D recording for the ‘Archaeology of Archaeology’ approach, which has been developed at the University of Amsterdam, see: In this approach, past archaeological activities at a site are studied by archaeological means in order to elucidate how past research questions, designs, results and interpretations have influenced knowledge about a site (cf. Murray & Spriggs 2017). Within this concept, the archaeological site is regarded as a laboratory in which, often for long periods of time, scientific research has taken place that has left its traces on the site. The current geography of a site such as ancient Troy, at which the approach is currently further developed, is determined at least as much by archaeological activities as by ancient habitation (Lucas 2012). Within the Archaeology of Archaeology approach, 3D recording techniques play a key role. They allow for creating a high-resolution and accurate digital twin of the archaeological site in its current state (1), facilitating the understanding of the topography of past excavations at complex sites (i.e. the spatial definition of trenches, dumps, pathways and stratigraphy), thereby contextualizing the old records, plans and photos of past interventions. With the help of such records it will become possible to reconstruct the archaeological site in its past state, before and during successive stages of excavations (2). Perhaps most importantly, a model of the site may serve as a central 4D hub, functioning as a study resource and allowing the interaction of different types of data and archival records (3). Since 2018, these three aims are being pursued at the site of ancient Troy in Turkey, where the Archaeology of Archaeology approach is being developed. However, the conceptualization of the 3D component is still in its early stages. In this round table, we would like to have an open discussion about the potential to combine 3D recording and 3D information systems with geographical and archival information of archaeological activities at a site. Where we have Troy as a case study, we hope to discuss wider implications with the participants of this round table. We invite scholars and students who work with varied datasets at complex archaeological sites and landscapes to share their experiences and ideas.

S24. How Are Archaeological Narratives about the Past Constructed? – Analysing Argumentation in Archaeology

Session type: Standard

How can data identified as a record of the cultural past be presented as evidence? How can these data support claims about the past that cannot always be verified? The elaboration of good and strong arguments is one of the key points to addressing this type of question. However, scientific publications often focus on showing how data has been obtained and analysed rather than arguing convincingly on a relatively small number of claims or points to be communicated. Especially, in the field of archaeological knowledge, arguing is particularly challenging due to its unique nature: claims about the past that cannot be indubitably verified (Lucas, 2019). Is it possible to analyse several lines of argumentation from the archaeological data to the conclusions and assess how well founded these conclusions are? The main aim of this session is to generate some cross-fertilization between argumentation theory and archaeological reason. Instead of treating the elaboration of arguments as a secondary step in the creation of archaeological knowledge, we should start considering it as an essential step, and enhance it with all the theoretical support that other studies in argumentation can provide.

Current Research
The most recent work studying argumentation of archaeological knowledge (Chapman and Wylie, 2016; Lucas, 2019; Smith, 2015) has developed proposals specifically focused on how good arguments can be elaborated. They are inspired by Toulmin’s (Toulmin, 2008) model of argumentation, having several limitations related to the variety and richness of the different ways in which people build different types of arguments in the field. We argue in favour of applying state-of-the-art contributions in argumentation theory to archaeological knowledge. For instance, annotated text corpora (Fort, 2016) and Argument Analytics (Lawrence et al., 2016) can be applied as an alternative to the Toulmin model. These techniques can be used to improve the outputs generated by research work, such as reports, fieldwork diaries, or scientific publications. On the other hand, we acknowledge that different texts can provide alternative views of the same underlying data, thus developing alternative lines of reasoning. Texts sharing similar views or defending the same claims can be put together into a corpus to be annotated and studies which allows us to explore inter-textual relationships (Visser et al., 2018; Gonzalez-Perez, 2020), that is, discover how texts and authors are interconnected and how the content of various texts cross-references and relies on the meaning of others. Lastly, the computational treatment of archaeological arguments is a field to be explored. The current explosion in the development of Argument Mining (Lawrence and Reed, 2020), together with the automated reconstruction of the argumentative structure of texts, opens up the possibility of massive treatment of argumentative texts in archaeology.

Expected Contributions
Research is necessary to generate cross-fertilisation between argumentation theory and archaeological knowledge. We need to provide a good conceptualisation of the argumentation concepts (premises, conclusions, argument schemes, supports, attacks, etc.) tuned to the specific characteristics of archaeological knowledge. Only when a solid theoretical basis has been established, we will be able to refine existing computational models of argumentation to deal with archaeological texts as appropriate. Expected Themes Papers are welcome in this session about the following topics, among others:

  • Philosophical accounts of argumentation
  • Relationships between discourse makers and argumentation in archaeology
  • Methodologies of discourse analysis applied to argumentation in archaeology
  • Theories, ontologies and conceptual models of arguments in archaeology
  • Uses of argument mining techniques for specific tasks in archaeological reasoning
  • Annotation of archaeological texts
  • Argument schemes for archaeological reasoning
  • Argument analytics for archaeological arguments
  • Argument analysis to question major archaeological paradigms (hunter-gatherers, gender stereotypes, state nations, complex societies, etc.)
  • Visualisation of argument analytics for archaeological reasoning Audience

The session will be of interest to:

  • Archaeologists concerned with a richer and more nuanced representation of archaeological reasoning
  • Students working on how to better defend a claim
  • Cultural heritage managers that use archaeological information for decision making • Developers of information systems aiming to capture and represent argumentation structures
  • Publishers or archaeological texts interested in improving the soundness and cogency of their materials

S25. CAA@50: standards of practice in computational archaeology

Philip Verhagen, Vrije Universiteit Amsterdam

Session type: Round table

Archaeology has evolved into a discipline where digital technology is pervading all aspects of the profession, whether dealing with documenting the archaeological record, analyzing data or presenting our findings within the archaeological scientific community, in education and to wider audiences. With the 50-year anniversary, we want to explore the role that CAA as a membership organization can play in shaping and maintaining shared standards of research and professional conduct in computational archaeology. In this roundtable, we want to shift the focus from the development of technological standards – which has been part of numerous CAA sessions in the past – to standards of practice. What are the core elements of ethically responsible and inclusive use of digital technology in the discipline? What is currently missing in this respect? What tensions can we identify in trying to achieve these goals, and how can we tackle them? What allies can we find within the discipline and beyond? In this roundtable, participants can give a short pitch on one of the following topics to be followed by a moderated, open discussion.

  • Engaging with Open Science
  • Achieving sustainability of practice
  • Embedding inclusive approaches
  • Ethical guidelines

The outcomes of the debate will be used to explore the possibility of setting up a Special Interest Group.

S26. For a Bright Future: Challenges and Solutions for the Long-Term Preservation of 3D and Other Complex Data in Digital Cultural Heritage

Session type: Standard

The age of digital documentation has dawned. Fully digital methods (e.g., the use of total stations, photogrammetry, laser scans, computer modelling, etc.) are used in fieldwork as well as in analysis and communication on a regular basis. Once an exception, these complex and multidimensional data tools are increasingly the rule, and their output often exceeds both the technological capacity and the workflows of existing institutional infrastructure. Specialist repositories such as the Archaeological Data Service (ADS), the Digital Archaeology Record (tDAR) and others have pioneered approaches to long-term data storage, based around international standards and concepts such as the Open Archival Information System OAIS (CCSDS 2012). However, the volume and variety of primary data have transformed the data storage landscape. As highlighted by Moore et al. (2022), there remains a high degree of variability in archiving approaches, not only across different specialisms but also within individual communities. At the same time, innovation and the wider adoption of technology in society are set to continue. It remains to be seen whether the broader application of the London Charter (Denard 2012), the FAIR principles (Wilkinson 2016) or new standards from the widely anticipated Metaverse (Metaverse Standards Forum) will be a positive standardising force or whether the developing technologies will only exacerbate existing challenges. The OAIS archiving strategy requires the stakeholders of a shared domain to enter into dialogue with one another for the purpose of developing a meaningful preservation plan. After all, the plan will require not only the expertise and perspective of the data managers, but also of those producing and supplying the data and the downstream data consumers. This session sounds the call for further discussion. It invites papers that present strategic and theoretical approaches to the preservation and future reuse of complex digital data, as well as examples of practical workflows which achieve this aim. We are looking for participation from governmental institutions and private companies as well as individual researchers, and for papers that encourage debate. We ask that submissions include a brief introduction to the organisation represented and recommend that the papers be based on a 3D-data case study, although discussions of other types of complex digital data are also welcome. The aim of the session is to spread awareness of different approaches and outlooks, to spark an international dialogue with broad participation, and contribute to building the foundations for a bright future in digital cultural heritage.

S27. Exploring new ways of visualizing archaeological data

Ralf Vandam, Vrije Universiteit Brussel
Georgia Panagiotidou, UCL Interaction Centre

Session type: Standard

Data visualisations are becoming common research tools in humanistic inquiry. Besides outputs of modelling efforts and communication tools, data visualisations help bring new perspective to otherwise familiar data (Lev Manovich, 2015). However, while visualisations for encouraging such rich and varied exploration are being developed in neighbouring fields of literature and cultural studies, archaeology seems to have few such explorative examples outside the use of GIS (Gupta and Devillers, 2017). Explorative interfaces created for humanistic research are made generous in their browsing (Whitelaw, 2015), speculative and playful in their interaction features (Hinrichs, Forlini, & Moynihan, 2016), semantically rich in their layouts (Gortana, von Tenspolde, Guhlmann, & Dörk, 2018) and critical in their points-of-view (Drucker, 2015). GIS allows for more efficient management and analysis of the collected spatial data and provides an easy way to map spatial archaeological data. However, traditional GIS mapping does not easily support temporal data, which can lead to a reduction of the complexity of archaeological phenomena (Andrienko et al. 2010). In this session we want to explore new ways of visualizations to better handle the different dimensions of (spatial) archaeological datasets to reveal new patterns and create new knowledge. Among others we are hoping to explore questions such as: How to visually unpack multidimensional datasets from long-running archaeological projects? What novel visualization techniques can highlight so far undervalued perspectives of spatial data? How can the inevitable uncertainties underlying the data be communicated in visualizations? While we welcome all types of visualization, the session hopes to attract papers with customized geovisualizations and non-traditional GIS mapping of archaeological data. The session aims to provide a stimulating discussion to identify problems and opportunities. We invite authors to provide a good insight into their methods.

Session type: Round table

At CAA 2022 in Oxford, the roundtable “Archaeology and Digital Humanities: The Road Already Travelled and the Road Ahead” produced a fruitful discussion on the commonalities and differences between Digital Humanities and Digital Archaeology, two fields that have seemingly evolved in parallel over the last two decades without much interchange. There is a chapter on “Computing for archaeologists” in (Schreibman et al., 2004), where the authors describe a barrier to the inclusion of archaeology as part of the Digital Humanities in these terms: “The discipline at large has not fully absorbed the need to preserve access to digital data for future scholars. It has not yet found an effective and relatively standard way to present digital data as part of a final publication. Its educational institutions have not accepted the need to prepare all archaeologists in the use of those computer technologies necessary in the field and the laboratory. In part, these problems reflect the nature of the discipline, a uniquely fragmented one consisting of practitioners who may have begun as historians, art historians, students of ancient languages, or anthropologists – but not as scientists dependent upon a tradition of prompt and full data sharing. The problems also reflect the unique independence of archaeologists, who must have a strong entrepreneurial spirit in order to fund and operate complex projects.” Of course, many of these barriers have been eased since then. A subsequent edition of the same work, (Schreibman et al., 2016), however, focuses on the methodologies and technologies used by the Digital Humanities rather than the epistemological or theoretical grounds of these fields, somewhat diluting their relationship. In addition, (Huggett, 2012) also points out that the relationships between digital archaeology and the Digital Humanities are difficult to determine, given the vagueness with which Digital Humanities have been described. This issue compounds the problem of tracing and studying the relationships between the two disciplines. In any case, the fact that both fields have been coexisting for decades and generating academic, professional, and disciplinary knowledge separately but bringing together very similar works in methodologies, approaches, and technologies merits a profound reflection on the implications and consequences of seeing archaeological computing as a branch of the Digital Humanities. The recent and ongoing evolution of digital practices in archaeology is reflected in the growing importance of contributions (articles, tools, events) from professionals who are not archaeologists. For some of them, mainly in archaeometry and archaeosciences, their training profile is often that of engineers from the sciences of the earth and the universe, with specialized skills in mathematics, statistics, model designing, computer and data science, programming languages. How can archaeologists cross points of view, compare conceptual models, make coexisting different criteria for the administration of proof? The round table will generate an open debate in which three guest speakers will offer position papers for and against placing archaeological computing work within the sphere of Digital Humanities, motivating the advantages and disadvantages of doing so, and delving into the possible weaknesses and strengths of doing so, showing real examples and/or collaborations. The main objective is to continue shedding light on this disciplinary relationship. The guest speakers will be invited considering their contributions to these fields, and ensuring that a diverse and comprehensive set of viewpoints are presented. Guest speakers (and hopefully attendees) will address these topics:

  • What is Digital Humanities? What is Digital Archaeology?
  • What are the commonalities and differences between the two fields in terms of theory, methods, techniques, and results?
  • How are multi-, inter- and trans-disciplinarity issues handled by each field?
  • Which of these differences are accidental, and which essential?
  • Can or should Digital Archaeology be considered part of the Digital Humanities?
  • How can Digital Archaeology benefit from the advance in Digital Humanities and vice versa?
  • What converging strategies are possible and adequate between the two fields?

S29. How do we ensure archaeological data are usable and Reusable, and for whom? Putting the R in FAIR for archaeology’s data

Sara Perry, MOLA (Museum of London Archaeology)
Holly Wright, Archaeology Data Service (ADS), University of York, UK

Session type: Standard

The last decade has seen extensive efforts to make digital assets more accessible and dynamic through experimentation with interoperability in cultural heritage aggregation infrastructures (e.g., the Europeana or ARIADNE portals). Such infrastructures allow static resources to be updated and cross-searched, but to do so, the metadata for these assets must be mapped in a centralised and controlled way. This can take the shape of mapping to a controlled vocabulary, thesaurus or ontology, which invariably reflects the types of terminology and relationships defined by those who are charged with curating the data (domain specialists), not those who might use the data in new and innovative ways. Digital data curation for cultural heritage has therefore reached a critical impasse. A central tension exists between the need to preserve cultural resources, and the dynamic potential for their use and reuse in democratic, just and compelling ways. At the same time, the introduction of the tetrarchy of FAIR Guiding Principles (Findable, Accessible, Interoperable, Reusable) for scientific data management and stewardship (Wilkinson et al. 2016) has set an important challenge: that each of the four principles is of equivalent importance and must therefore be engaged with equally. Within archaeology, much work has been done over the last 20 years to make data Findable, Accessible and Interoperable, but very little is understood about whether data are Reusable–and by whom (Wright and Richards 2018). The impact of this gap in knowledge is profound, as cultural heritage data are increasingly drawn into divisive debates, dangerous speech, cross-border misinformation-sharing and xenophobia, therein compromising human solidarity and social cohesion (e.g., Bonacchi and Krzyzanska 2021). Newly-funded through the Transformations: Social and cultural dynamics in the digital age programme of the Collaboration of Humanities and Social Sciences in Europe (CHANSE) Consortium, Transforming Data Re-use in Archaeology (TETRARCHs) argues that the future of digital curation depends upon reconciling this divide between collection and reuse. It aims to demonstrate that data optimised for ethical and emotive storytelling will provide the bridge between those who find or preserve heritage assets, and the diverse cross-European audiences for whom they might generate meaning. TETRARCHs builds upon international initiatives which seek to improve the accessibility of digital cultural heritage data via interfacing with those data: browsing them, searching them, and retrieving them in more ‘generous’ ways (e.g., (Whitelaw 2015). However, even as such experimentation grows, the assets themselves continue to be bound by relatively narrow classifications imposed by experts. Herein structure and reliability are maintained, but relevance and accessibility to the wider world remain limited (Manzo et al. 2015). The stories that can be told through the data are often narrow and pre-determined, with the vast majority devoid of affect, sensuality and agency (Krmpotich and Somerville 2016). The urgency of the predicament is heightened by growing interdisciplinary acknowledgement that this rift is directly linked to systemic bias, social inequity and racial injustice in data repositories (Sanderson and Clemens 2020). Efforts to rectify these biases include archival redescription (Pringle 2020), revised ethical metadata standards (Farnel 2018), felt-experience conceptual model extensions (Canning 2018), and alternative ‘fluid ontologies’ (Srinivasan 2018). The imperative for change to data infrastructures is overt. Yet recognition that such change must begin from the moment the data are conceived (as opposed to the moment they are deposited into a repository) has been slow in coming. Furthering our argument is the rapid pace of innovation with data acquisition technologies (Morgan et al. 2021), whose workflows still fail to capture important descriptive detail, emotion, human values and multiple viewpoints. Even as community-driven practices grow in popularity, fundamental redesign of our workflows and data to embed communities and justice at their core is still lacking (Dolcetti et al. 2021). Design Justice frameworks enabling such value-led, co-created redesign of digital structures are blossoming (Costanza-Chock 2020), but their systematic use in fields like archaeology is effectively nonexistent. Through an interdisciplinary team of archaeological specialists, data scientists, and museum practitioners, collaborating with three key user groups – domain experts, creative practitioners, and memory institutions – TETRARCHs will offer those who gather, curate and apply cultural heritage data with critically-aware workflows to prepare their data for enhanced re-use at every point in the data lifecycle (e.g., capture, mapping, lab-based analysis), then scenario-test such re-use through the dissemination of new narrative outputs authored by cross-European creative practitioners. The project embraces three scales of data collection in archaeology – landscape, site and artefact – exploring them via four increasingly ubiquitous technologies for data capture: airborne LiDAR, 3D scanning, digital field drawing and photography. Alongside novel workflows for field, post-excavation and archival practice, TETRARCHs will produce a controlled vocabulary for cultural heritage storytelling, assessments of data reuse effectiveness following ISO Standard 25022: Measurement of Quality in Use, and best practice recommendations for trusted digital repositories to optimise archaeological data for re-use. This session invites papers on the use and reuse of archaeological data, including case studies, examples of challenges and good practices, provocations and blue-sky thinking for the future of data re/use. Contributors may wish to engage with the themes of TETRARCHs or stretch beyond them. By hosting this session early in the life of TETRARCHs, we hope to foster discussion and collaboration with others who have comparable interests, and ensure that our outcomes are shaped in concert with such intersecting work, and are meaningful to the CAA community at large.

S30. Crossing Landscapes of the Past: Developments in Modelling Mobility and Connectivity in Archaeology

Andrew McLean, University of Edinburgh
Xavier Rubio-Campillo, Universitat de Barcelona

Session type: Standard

Recent trends show that the variety of computational approaches available for modelling mobility and connectivity across past societies are numerous and diverse. In the past employing techniques such as network analysis agent based modelling simulations or GIS to shine far greater light on the cost mobility and connectivity associated with the movement of goods and people across ancient landscapes. Advances in simulations network analysis and more complex GIS based connectivity models can be clearly noted in disciplines such as ecology but many of these new perspectives have yet to be widely adopted or discussed in archaeological contexts. Fairly well established techniques such as Least Cost Path (LCP) analysis remain the most common approaches and can provide insight into routes and journey times. However LCP is limited in the data it can provide beyond optimal routes between two fixed points. Furthermore while maritime movement was of major importance across the ancient world applying such analyses to these more complex contexts is an arduous undertaking. There have been attempts to address the difficulties with LCP but these need to be more widely discussed and understood. Innovative new methodologies have the potential to offer greater scope for improving quantitative studies. The aim of this session is to bring together scholars and researchers utilising the most cutting edge techniques for understanding movement across past landscapes. These techniques can be aimed at modelling new and more complex scenarios or presenting methods for overcoming some of the issues with the more well established techniques. It is especially hoped that researchers working with methods for understanding movement that are less widely understood in archaeology will contribute and help to improve our overall understanding of this ever evolving subject matter. We welcome speakers studying traditional LCP or network analysis for terrain beyond the purely terrestrial such as maritime or fluvial. Beyond this we are particularly eager for papers that discuss new techniques that are not necessarily well known in archaeology (or beyond) but which have a strong focus on quantitatively modelling mobility and/or connectivity across ancient landscapes. With all of this we hope to foster discussion of the most current and promising approaches to modelling mobility and connectivity available to archaeologists.

S31. Better Together: Exploring methods and applications for the synergy of multiproxy data in the study of archaeological mobilities

Christianne Fernée, University of Bristol
Konstantinos P. Trimmis, University of Bristol

Session type: Standard

Archaeological data are inherently multi-layered, commonly fragmented, and interpretations of past events are usually based on a variety of datasets that are often not linked together or aligned. To date, the problematic nature of archaeological datasets is well documented, and sparked the early criticism of endeavours in New Archaeology (e.g. Earle and Preucel 1987; Hole 1980; Hurst Thomas 1978; Shanks and Tilley 1982). However, as suggested by Hurst Thomas, ‘trends in research swing back and forth like a pendulum’ (1978: 240), thus meticulous analysis of archaeological datasets through applications of statistical and computational modelling are again the norm. In the last decade the interpretational ‘gap’ between the descriptive and testing statistical applications has been reconciled. The introduction of Data Science and Artificial Intelligence (AI) to the archaeological discourse are helping archaeologists to gain a deeper understanding of their data (see Fernée and Trimmis 2021). The involvement of these disciplines in the field of archaeology has the potential to pave the way for the integration of different datasets, brought together to address archaeological questions. Interpretations of archaeological data are not just increasingly based upon computational methods, but also on multi-proxy approaches. In this session we are interested in multiproxy approaches that have been developed to record, interpret and understand mobilities. It is common for projects to bring together quantitative data from multiple proxies, such as isotopes, radiocarbon dating, organic residue analysis and petrography, with qualitative approaches, and occasionally creative approaches, such as creative writing, applied arts, drama, and theatre (see methods discussion in Skeates 2010 for example). In addition to these multiple proxies, archaeological theory is also advancing, suggesting ways that interpretation can be broader, inclusive, less biased and more tailored to the societies under study. In this session, mobility refers to any form of human movement. From the short—term movement of people through spaces and places, singular migration events, to fully nomadic lifeways. The footprint of mobility results in data in many forms that gives insight into different aspects of mobility. Some of these include: 1) geographical information, from archaeological isotopes and aDNA, 2) biological implications, with evidence of the impact on the human body, and 3) material culture variations, with the replacement, continuation or transitions of material culture. Thus, a question arises; How can we achieve data synergy by bringing together so many different types of data, ways of collection, analysis, and interpretation, to help us record, interpret, and understand archaeological mobilities and their impact? Data synergy is employed in this session to describe data from multiple sources and/or disciplines that, when combined, are more valuable than any of the sources alone (see Higginson et al 2018). Regardless of the type of dataset, in this session, we contend that good data is dependent on four interlinking dimensions: a). Time (synchronising the collection and sharing of data), b). People (coordinating the collection and sharing of data), c). Technology (establishing the different technologies so that data can be transmitted), and d). Quality (ensuring data is good enough for the research purpose) (see Higginson et al 2018). The discussion will examine challenges in relation to these dimensions in order to make recommendations for the development of a data synergy protocol for use in multiproxy and multidisciplinary projects. In this session, we would also like to further expand the discussion onto ways that synergy can be achieved between quantitative and qualitative approaches, and approaches that link data analysis with thick description in an archaeological context. The session aims to present and discuss methods, applications, and case studies that advance data synergy in the study of archaeological mobility. The session welcomes papers that focus on but are not limited to: a) Discussing novel computational methods that advance the synergy of data collection, curation, analysis, interpretation, visualisation, and archiving. b) Presenting case studies where these synergies have been tested or achieved. c) Discussing ethics and good practice of such synergies in archaeological contexts. d) Presenting software applications, ‘how to’ ways, and solutions that communication and synergies can be achieved. e) Discussing future challenges that synergies can face on the landscape of the ever-increasing data qualities, quantities, and types. Overall, this session would like data science to be in synergy with current archaeological theory, that views archaeological evidence of mobility (and beyond) as more connected and entangled. People, as they move through space and between places, are in a constant and everlasting interaction with their surroundings, their own and other cultures. Archaeology, however, often look at people, environments, and material culture as single strands of evidence that can assist towards a better understanding of the past; and the consequent modelling of the future. We welcome researchers that are working to bring these strands together, particularly those working at the intersection between data science and archaeology. By bringing these researchers together this session hopes to advance a better understanding of how different data can work better together for the study of human mobility.

Over the last decades, ancient historians and archaeologists have slowly realised the potential network science holds for studying past phenomena and better understanding the relationships that connect entities under study. By now, we have employed diverse network perspectives to explore a variety of sources and datasets that help us shed light on the past (for overviews, see e.g. Brughmans 2013; Collar et al. 2015; Crabtree & Borck 2019; Knappett 2013; Knappett 2020; Peeples 2019; Rollinger 2020). We have built and analysed networks to answer questions about social and interpersonal networks, trade routes, production and consumption patterns, group behaviour, diffusion of ideas and technologies, social mobility, and other complex phenomena (Brughmans 2021; Cline and Cline 2015; Verhagen 2018).

Networks have been popular in diverse disciplines such as biology and physics, and their application and full implementation to archaeology emphasises the structural representation of the relationship between objects, people and places, guiding recent discovery on land use, ancient demography, past economies and trade (Brughmans 2013, 2021; Graham 2006; Verhagen et al. 2019). While not yet fully explored in the area of art-related crimes and in connection with issues of illicit trafficking in cultural heritage (Tsirogiannis and Tsirogiannis 2016), network analysis has also been successfully used to study degrees and manner of relations among criminal individuals and groups, and to investigate other forms of criminal organised trades, such as human (Vivrette 2022), drugs (Tsai et al. 2019) and wildlife trafficking (Costa 2021). It is, therefore, interesting to survey further intersections of network analytical applications to multiple fields, both in micro and macro perspectives.

Network science offers a plethora of conceptual and digital tools that allow networks to be measured and explored with formal methods, and archaeologists, historians and digital humanists have found aspects of Social Network Analysis (SNA) particularly useful (for an introduction to SNA, see e.g. Graham et al. 2016: 195-234. For handbooks, e.g. Borgatti et al. 2013; Scott 2017; Wasserman and Faust 1994). Learning to handle the uncertainty of the data and refining network modelling techniques are, however, paramount for a correct and scientific reconstruction of past interactions (Birch and Hart 2021; Carreras et al. 2019; Verhagen et al. 2019).

Even within the subfield of SNA, a range of methods and software packages are available for researchers and they provide analytical tools for exploratory as well as descriptive analysis (links below). Their relevance depends on the researchers’ topic, source material, dataset, financial means, technical skills, etc. – all of which may be decisive factors when choosing ones software (Graham et al. 2016: 237-240). For small datasets, the MS Excel extension NodeXL might suffice, but Gephi – which is freely available, works on all platforms, offers a variety of tools and plugins, is relatively easy to learn and has buttons to press (in exchange for code to be written) – quickly became popular in historical and archaeological network studies. For larger datasets or more complex statistical and network analysis, UCINET, Pajek or R might be more appropriate, but they require the researcher to engage more directly in the calculations and thus have steeper learning curves. For visualising and analysing networks that are dynamic, multivariable, longue durée or have a particularly strong emphasis on spatial data, yet other applications – like Nodegoat or the Vistorian, which are more specialised towards archaeological and/or historical data – might be the preferred choice. And often, the best solution might be to form interdisciplinary research teams (Verhagen et al. 2019: 237-238).

Since archaeologists and historians tend to work with different source materials and research questions, they are likely to utilise different software or apply different tools offered by them. The fields of historical network research and archaeological network analysis have thus developed in different directions – with historians more commonly exploring social whole or ego networks and particularly central figures in them, and archaeologists e.g. placing a larger emphasis on spatial data and compatibility with Geographical Information System (GIS), Least-Cost Path (LCP) analysis and other types of modelling (Benvan and Wilson 2013, Carreras et al. 2019; Groenhuijzen and Verhagen 2016; Lewis 2021; Verhagen 2018; Verhagen et al. 2019: 233ff.). Scholars who routinely employ network analysis to study archaeological and historical data nevertheless have a lot of common ground, in that they strive to increase our knowledge of the past through distinct network approaches and face many of the same challenges in the process (Brughmans et al. 2016; Ryan and Ahnert 2021: 61f.).

Roughly a decade ago, Lemercier (2012) and Brughmans (2013) reported general unawareness of the history, underlying sociological theories, and diversity of existing network approaches in history and archaeology respectively. That many new and creative studies have since seen the light of day is for instance reflected in the events of the flourishing Connected Past community and the online bibliography and newly launched Journal of Historical Network Research (links below). Studies critically testing the performance and robustness of formal measures on network models of the past further indicate that the fields have matured and progressed (Groenhuijzen and Verhagen 2016; Ryan and Ahnert 2021; de Valeriola 2021).

Despite an increasing number of network studies in archaeology and history, Holland-Lulewicz and Thompson (2021: 2) recently reported, that “such applications remain limited to cases employing either solely archaeological evidence or solely documentary evidence”. Acknowledging that increased dialogue between the two communities can help raise awareness of relevant (combinations of) tools and inspire new projects, methodologies and collaborations, this session aims to strengthen the ties between historically, archaeologically and cultural heritage oriented network researchers by bringing them together to discuss, share experiences and showcase relevant methods. In doing so, it welcomes papers that integrate the communities, studying both written and archaeological evidence, reflecting on the directions one or both subfields are taking, presenting research from collaborative teams, etc.

In striving to create an interdisciplinary, inclusive and diverse platform for such discussions, we encourage scholars working on all periods and geographical regions – regardless of background, identity, field and affiliation – to submit an abstract on active case studies. Research topics could include (but are not limited to):

  • skills transfer in archaeology;
  • modern use of archaeological data in the political discourse;
  • illicit trafficking of cultural heritage;
  • past and contemporary trade networks;
  • interpersonal relations of individuals and groups;
  • linguistic and semantic networks;
  • dynamic network models;
  • software and methods for studying historical and archaeological data.

S33. Bayesian Inference in Archaeology: new applications and challenges

Session type: Standard

The archaeological record provides a unique opportunity to study past human behaviour . Its record, nonetheless, is not straightforward to analyse — it is scarce, noisy, biased, incomplete and unevenly distributed over space and time. Bayesian statistics offers a inferential framework that is well suited for tackling these problems, offering ways to quantify uncertainties arising from these limitations and providing means to take them into account when drawing our conclusions. Bayesian inference has made great advances recently. While initial applications in archaeology were limited within the confines of chronological modelling and few dedicated softwares packages (e.f. OxCal and BCal). The last decade saw a major change – with applications including faunal analyses, diet reconstructions, paleodemography, past economy, and cultural evolution to name a few examples. This major change in archaeological practice was made possible thanks to the increased computational power of desktop machines , a the availability of a large number of probabilistic programing languages (e.g. JAGS, Stan, Nimble,etc.) , a growing number of “hands-on” literature on Bayesian methods (McElreath 2020), and the increased number of scholars across disciplines sharing their scripts and code to ensure their work is fully transparent and reproducible..

With this session we want to capture this momentum by proposing a showcase of how archaeologists face their own specific problems using formal inference and probability theory, but also a broader reflection of where we are and where can we go using these types of techniques. In order to do so, we raise a series of questions:

  • How can Bayesian statistics and probability theory help understanding the archaeological record?
  • What are the specific archaeological challenges in applying techniques designed to handle measurement error and missing data?
  • What probabilistic methods can/are being applied within archaeology?
  • What are the specific challenges in re-using inferential models developed in other fields within archaeology?

By bringing together archeologists who already apply Bayesian inferential techniques to their work or are interested to do so, we hope to increase the awareness and visibility of such methods in the larger field of archaeology. By showcasing successful examples of application of probabilistic inference in archaeology, we hope to convince people of the power of such an approach. Finally, we also want to offer a platform where researchers using Bayesian approaches can share knowledge and keep themselves up to date with the latest techniques in use.

We invite proposals of any applications of Bayesian statistics in archaeology, with particular interest in the following areas:

  • Hierarchical Modelling
  • Gaussian Process Modelling in Spatial and Temporal Analyses
  • Bayesian Networks
  • Phylogeography and phylogenetic Analyses
  • Inference with missing Data and measurement errors
  • Mixture Models
  • Likelihood-free methods (e.g. Approximate Bayesian Computation, Bayesian Synthetic Likelihood)

The session is not limited to any chronology or geographical area and may include case studies, theoretical reflections, methodological innovation and assessment, etc. Innovative approaches and novel insights are particularly welcome as well as students and early career researchers who want to present preliminary results.

Past natural and human activities have left marks on the landscape of every type of environment on the surface of our planet. These can be recognized even after millennia; they can be ephemeral or clearly apparent. Their visibility is dependent on the time passed and the natural or human activities that took place over time, but many of them can be detected via remote sensing techniques. Arid environments often experience strong dusty winds and a continuous movement of dunes or soil particles. These conditions can quickly and entirely cover (or preserve) historical and paleo-environmental remains, creating an obstacle to ground surveys, and a hindrance to some remote sensing techniques. Remote sensing methods focusing on far distance optical, radar and multispectral scanning, allow researchers to overcome these obstacles, providing valuable information about modern and ancient geomorphological, hydrographical, environmental, and archaeological evidence. In the past few decades, many arid areas of our planet have been scanned via various remote sensing methods, and many of the images are in open access repositories, meaning that there is a wealth of information freely available. Archaeological studies initially focused on the analysis of space photos coming from declassified spy satellites (Corona and Hexagon) and optical imagery from Landsat, SPOT, and ASTER missions. This was followed by work on Very High Resolution (VHR) imagery from Ikonos-2, QuickBird-2, GeoEye-1, WorldView-1/2/3/4, Pléiades-1A/1B and Pléiades Neo missions. These images offered unparalleled resources to the manual detection and analysis of the archaeological sites. Recently, UAV photography, 3D modelling, and free commercial optical satellite and aerial imagery provided by web map service such as Google Earth and Bing Maps has opened up new avenues of research. Satellite radar imagery (as opposed to photographs) coming from SIR-A/B/C, AIRSAR and SRTM SAR or 2nd generation multi-bands SAR systems such as ALOS PALSAR, TerraSAR-X/TanDEM-X, COSMO-SkyMed and Radarsat-2 or aerial/UAV LiDAR scans that penetrate the superficial covering layers and reach the historical traces have been invaluable. Archaeologists have now also started to exploit the resources coming from multi-spectral (and soon hyper-spectral) satellite missions like Sentinel 2 to detect or monitor historical features via their spectral signatures. All this information was (and usually is still), processed through a variety of manual techniques, enhancing archaeological marks and proxy indicators, and post-processed via various human operators analyses and protocols. Recently, many new automatic supervised and unsupervised computational approaches (Filters, Machine and Deep Learning algorithms, AI, etc.) have added powerful new tools and workflows to the thematic interpretation of images with considerable savings in the processing time. The results of all these studies have already enabled archaeologists to detect many new archaeological sites and paleo-environmental features. This facilitates the monitoring and measurement of conservation risks of endangered historical sites, and the unveiling of ancient pathways, hydrological features, and settlements. All of this contributes to the planning of effective conservation strategies and study and re-use of hidden resources, in collaboration with local and international authorities. The session we are proposing will focus discussion on the results coming from studies relating to the usage of aerial/UAV/satellite remote sensing resources; manual and automatic computational workflows of image analysis; and the limitations and opportunities of these techniques applied in desertic and arid contexts for the aforementioned purposes. We therefore encourage the submission of papers that highlight innovative remote-based archaeological applications in desertic areas, following or proposing similar topics:

  • Use of multi-petabyte repositories of geospatial datasets in arid environment
  • Remote sensing analysis of large areas or landscape analyses over time-series in arid environments
  • Application of complex computing, cloud-based computing, or multiplatform workflows to overcome archaeological remote sensing problems in desertic areas
  • Geospatial data processing and post-processing via manual procedures (Analysts training, Analyses Protocols, Database, etc.) and automatic/semi-automatic approaches (Filters, Machine Learning and Deep Learning algorithms, AI, etc.) in arid environments
  • Joint or integrated use of optical, multispectral and radar satellite imagery
  • Derivative works coming from remote sensing and computational analyses to study, monitor and preserve historical contexts or plan future activities in desertic region in agreement with local, international, public or research institutions

S35. Indigenous Knowledge and Digital Archaeology: potential, problems and prospects

Eleftheria Paliou, University of Cologne
Patricia Murrieta Flores, Lancaster University

Session type: Standard

To date, several research projects have sought to establish collaborations between indigenous communities and archaeologists. Such works have drawn attention to the benefits but also the challenges of combining archaeological theory and methods, including digital and computational methods, with indigenous worldviews. On one hand, the use of digital technologies in archaeological projects engaging indigenous communities has offered new possibilities for the preservation, management and interpretation of archaeological heritage and valuable insights into critical and widely debated themes in archaeological and anthropological research (Raichlen et al. 2014; Wood et al. 2021). At the same time, interactions between local communities and digital archaeology experts have opened up new opportunities for reciprocal knowledge transfer, and, in some cases, the economic sustainability of indigenous groups. Nonetheless, the use of digital methods in indigenous archaeology and heritage has also raised a number of issues with respect to the imposition of colonial practices and frameworks, ethical conduct in scientific practice, and equitable participation in data governance (management, ownership, accessibility) and knowledge production (Gupta et al. 2020; Sanger and Barnett 2022). This session invites papers that discuss the potential and challenges of using digital tools and methods in collaborative research between archaeologists and indigenous communities. We especially encourage contributions that focus upon (1) the experiences and benefits of interacting with indigenous communities to advance digital archaeological research and computational modelling, (2) the integration of indigenous knowledge systems into data capture, digitisation, dissemination, and analysis and (3) the ways in which digital archaeology can support the economic sustainability of indigenous groups and empower indigenous communities to investigate and communicate their past.

We are also interested more broadly in papers exploring synergies between indigenous knowledge and digital archaeology, and contributions that discuss ethical considerations related to the participation of indigenous communities in digital archaeological research.

Archaeology produces and deals with information collected and created by archaeologists. Just as there are many Archaeologies, there are also many ways to collect, interpret and analyse data and many approaches to archaeological thinking.

The use of statistical methods in Archaeology reaches back to the end of the 19th century (Petrie 1899) and became computer-based after the middle of the 20th century. The first applications of statistical-mathematical methods using computers transformed the handling of spatial and quantitative data (e.g. Goldmann 1979) and the view on Archaeology itself (e.g. Clarke 1968; Hodder and Orton 1976; Ihm and Zimmermann 1978) which facilitated the use and combinations of diverse data sources. This quantitative-statistical analytical view prepared archaeologists for the advent of publicly available, high-resolution digital data, which revolutionised and broadened Archaeology.

Through time, statistical approaches were adopted for a broad range of spatial analyses. The most impactful methods were applied on landscape scale, such as the conversion of paper map data to digital elevation data (e.g. by the Ordnance Survey of UK), along with the evolution of mapping itself. From this developed Landscape Archaeology, which adopted the use of remote sensing data, branching into a whole new discipline: Archaeological Remote Sensing (ARS). The new data sources, including geophysical platforms, led to the need for handling big spatial data and thence to the specialised use of GIS platforms (O’Sullivan and Unwin 2010; Wheatley 2004). The development and application of methods such as predictive modelling (Leusen and Kamermans 2005; Kamermans et al. 2009), along with the early realisation of the importance of sampling and the use of statistics (Banning 2020 in Gillings et al. 2020), followed. Such large amounts of detailed data have led the quest across real landscapes requiring the use and/or development of appropriate statistics (Lloyd &Atkinson 2020 in Gillings et al. 2020). These large individual ‘scapes’ became the bases for broad, cross-area relationship studies, representing human interaction.

For most areas of archaeology there has been a hand-in-hand development of scientific tools and statistical analyses. ARS has seen the sophistication of airborne platforms, sensors and imaging technologies, like LiDAR, hyper-spectral imagery and drone derived imagery (Agapiou and Lysandrou 2015; Luo et al. 2019)which have helped the diversification of this sub-discipline’s toolset. Such technical developments continuously push specialists to look for, borrow and adapt methods to analyse big data. We see machine learning (ML) as automated statistics becoming a common method for archaeological analysis, particularly in Landscape Archaeology (Orengo et al. 2021; Verschoof-van der Vaart and Lambers 2019). With significant developments in the last few years, ML has rapidly gained importance and is not likely to diminish in the foreseeable future. Although Automated ARS is still in its infancy (Opitz and Herrmann 2018), the use of scripting languages (Carlson 2017) and FAIR principles (also in other Archaeologies) point also towards a promising future.

This review brings to the fore some major statistical developments in archaeology, and despite its impact and heavy use in archaeology today, we have noticed that sessions dedicated to statistics rarely occur at the CAA in more recent times. Therefore, for the 50th anniversary of the CAA, this session would like to critically reflect on lessons learnt in the past or investigate the importance of statistical thinking today in Archaeology.

The main question we ask is: are we there yet?

Enfolded in this main enquiry are the following issues: are we heading in the right direction? Are we using the tools in the right way: have either qualitative or quantitative statistics let down researchers by misleading or confirming an archaeological ‘truth’ in the past that has since been overturned due to new data or approaches (Bergh et al. 2021)? Models and predictions are great tools – but where do the pitfalls lie? So, as archaeologists, are we mostly misled by the theory of statistics concerning the actual application? How to bridge the gap?

We request successful and cautionary tales to disseminate this topic and point to possible directions to counter this. Have we found “the” solutions to old questions with the ever renewing tool boxes or are we always facing new questions? Do we have standardised/formalised methods for specific problems? Do we use all tools available to also communicate and disseminate research for others to build upon? Are our methods FAIR and reproducible ? If so, or not, why (not)(Berberi and Roche 2022)? What should we be doing about it?

So, ARE, we there yet? We invite the CAA community to consider and discuss the relevance of statistical thinking and application in Archaeology in the past, today and in the future.

S37. Modelling the semantics of space – the relationship of entities creating space

Aline Deicke, Philipps-University Marburg

Session type: Standard

Over the past 50 years, digital archaeology has made enormous progress in unlocking the potential of computational approaches for the study of the human past. Particularly the application of quantitative methods on archaeological research topics has been quite extensively researched and conducted with immense success. Yet, in light of a growing awareness of the supposed objectivity of numbers and so called hard facts, ways of conceptualising, analysing and interpreting archaeological data using qualitative methods and theories have come into focus – on their own as well as in their interplay with quantitative approaches. The challenges of the fragmentary nature of the material record, the vagueness and the uncertainty implicit in data of the past, pose particular risks in archaeology and ancient history that yet also offer rich potential: Especially with increasingly interdisciplinary research tendencies, the combination and entanglement of quantitative studies with in-depth critical perspectives on the complexities of micro as well as macro patterns through the soft facts will open up this data to new and innovative avenues of research.This session aims at bringing the intangible data and approaches, techniques or applications using qualitative data into the spotlight. The extension of a quantitative focus with qualitative perspectives becomes especially evident in a field of research central to all archaeological disciplines: The study of space. Archaeology as a discipline relies primarily on three-dimensional data of spaces and objects that is very often expressed in quantitative measurements, be it length, volume or coordinates. For this reason, historically the use of analytical techniques that specifically investigate the constitution, development and shape of physical environments and/or assemblages (down to the decayed human body) are usually in the centre of attention. Apart from widely used tools – for example GIS software – and the research paradigms they embody, this focus becomes evident as early as in the data modelling stages of research processes. For example, the spatial relations as codified by the CIDOC CRM do not allow for detailed description of the interactions between actors and places nor for more complex perspectives on the spatial relations between objects that extend its – at heart – positional approach (Bekiari et al. 2022, xxii–xxiv). However, as early as the 1960s, processual archaeologists understood that the measured, physical environment was not sufficient for investigating ancient societies. As a first attempt to circumvent the problem, they extended the concept of landscape in a new way by including qualitative data, such as semantics or symbolism, into their research. At the same time, sociologists like Lefebvre (1974) redefined the concept of spatiality, which in their understanding was the outcome of social relations independent of the actor´s social class. In the 1990s, further work conceptualised organisational structures in the context of space, a movement that was shaped especially by Martina Löw’s work “Raumsoziologie” (Sociology of Space; Löw 2001). This perspective, which entered cultural studies as the so-called spatial turn, enabled researchers to study (past) societies in their holistic complexity and, above all, free from hierarchical, mostly elite-oriented models of society. Nowadays, such relational models of space that are able to speak about intention and reception in the constitution of space as well as social action rather than mere construction have found wide acceptance and usage in most fields of the humanities (Werlen 1993). In the archaeological disciplines, space as a witness of social organisation can contribute to a broader and multi-faceted understanding of our cultural heritage. While, every so often, these theories and concepts have found their way into archaeological research (e.g. Gramsch/Meier 2013, Maran 2004/05, Thaler 2044/05), their translation into specifically digital archaeology still seems to be in its infancy. This opens up a wide field for digital archaeology which has not sufficiently spread in our discipline: How can we conceptualise data models that prioritise the construction of social entanglements in their envisioning of space and spatial relations? How can we enable interoperability between such models and which aspects would this interoperability even address? How can we open up these qualitative approaches to quantitative analyses such as network research or ontology engineering, and how can we include the critical perspective necessary to interpret the results in this process? With this session, we focus on these and many other questions on computational approaches along all stages of the research process. Therefore, the session is open to all contributions concerning digital approaches to space as a social construct in archaeology and its related fields, ranging from conceptual models to analytical tools and methods to the development and applications of software, and many more. We welcome papers from any academic stage and encourage especially students and junior researchers to present their work, even if in progress. We are also very keen to receive abstracts from established scholars who may share the pitfalls and risks in integrating qualitative data into the evaluation of past societies.

S38. Computational Modeling Water-Based Movement

Emma Slayton, Carnegie Mellon University

Session type: Standard

Computational Modeling Water-Based Movement This session invites members of the Computational Modeling Water-Based Movement Special Interest Group, and those with similar interests and research foci, to present updates on their work. As this computational archaeological focus is still developing (excitingly with an increasing number of papers at CAA every year), many researchers still have their own singular methods, applications, and algorithms to discuss past mobility practices. Despite the presence of several publications on these themes (see bibliography), there are still those just starting in this work who are unaware of our developing community, or researchers who are deeply involved in this type of modeling who are not connected with other corners of the community due to a difference in the focus of region or time period. Scholars researching similar questions are often unaware of one another’s work and theoretical underpinnings, which in turn can lead to the re-invention of the wheel, duplicated projects, and individuals needlessly struggling to overcome challenges that have been tackled and solved by other researchers. Having researchers learn about what else is happening in the field can only serve to broaden the capabilities of our work as a whole. For example, where different approaches have been applied to address similar topics we can learn from each other’s successes and failures. Many researchers have explored Agent Based Modeling approaches in similar areas to where deterministic pathway analysis has been used, with different climate data as the base (e.x. Smith 2020 and Litvine 2022), helping to point out the benefits of each approach. On the flip side, we have several researchers using the same approach in the same region (e.x. Blakley 2018 and Poullis et al 2019), but with different results that can help researchers judge the fidelity of different projects. Recent efforts to combat the siloing of researchers include the creation of the CAA Special interest group sharing the name of this session, as well as several other sessions and roundtables at past conferences (e.g. Kyriakidis et al. 2022; Slayton et al. 2022). In addition, this session seeks to build off outcomes of the CAST conference held at Stanford in 2022. In the spirit of these past sessions, and newly concentrated interest modeling water-based mobility in the past using computational means, this session seeks to further develop this community. We hope to bring together researchers from multiple corners of this discussion, including but not limited to computational archeology, anthropology, oceanography, atmospheric sciences, geography, and computer science. We encourage our colleagues working in this area to submit paper on various aspects of modeling movement across water including (but not limited) to: Case studies exploring seafaring and voyaging using computational methods Case studies exploring coastal environments using computational methods Use of water modeling as outreach (e.g. computer games, VR experiences) Evaluation of theory employed to add context to computationally modeling water based mobility Issues facing the field of water movement modeling Finding, using, and maintaining climate data sets for use in modeling Through this session we hope presenters will explore and showcase various approaches to analyzing and researching maritime spaces. We also hope this session brings together researchers who participate in maritime digital archeology, so as to further develop participation and interest in the Computational Modeling Water-Based Movement Special Interest Group.

S39. Web-database solutions for the excavation datasets

Session type: Standard

Contemporary field archaeology can be characterised as a rush into use more and more digital research methods. The consequence of this is the collection of a wide variety of data: beginning with digitised paper documentation, through spreadsheets such as Excel, Access, photographs and drawings, to very specialised data such as 3D models, microscopic images, non-invasive prospection data or imagery acquired from a variety of platforms like UAVs or satellites. This diversity and volume of data generate several problems facing modern field archaeologists. These problems can be put into a few key points:

1) The storage of collected data in a single environment, which should allow the active use of this information, both at the fieldwork and study levels.
2) The accessibility of the acquired data so that it can be viewed, edited, or used by as wide an audience as possible, in the first instance by expedition members, more widely by the public.
3) The state of existing database solutions. Many emerging open databases are the result of scientific or development projects, and often after the end of their implementation and amortisation period, such solutions are no longer developed or supported. It causes a decrease in their usability, reliability, and significantly hinders their development. This last problem is especially relevant from the point of view of archaeologists who in such a case have to bear the costs for the maintenance and development of their chosen software.

We would like to ask a question and discuss the following issue: Is the rapid development of web-based data solutions for archaeologists an answer to a growing number of data gathered during excavations and a need for its digitization?

For our session, we would like to invite researchers who could share their experience with implementing and using both commercial and open-source databases based on web-based solutions in their excavation practice. From initial excavation recording, surveys, through advanced studies, post-excavation analysis, research and dissemination or archiving. Both small or time-limited projects and large, long term projects with a complex structure will be a point of interest.
If you are using databases solutions like Arches (The Getty Conservation Institute), Portable Antiquities Scheme (the British Museum and Amgueddfa Cymru – National Museum Wales), Open Atlas, FAIMS (Macquarie University), The Archaeological Recording Kit (ARK), HEURIST (University of Sydney) or any other specially designed web-database, we would like to encourage you to talk about your experiences.

S41. Capacity building for open data persistence in archaeology

Holly Wright, University of York
Edeltraud Aspöck, Austrian Academy of Sciences, Austria

Session type: Standard

As we work to increase the amount of archaeological data that is freely available online, much of the data that is currently available still cannot be considered to be persistent. In other words, just because something is online, doesn’t mean work has been undertaken to ensure it will be available in five or ten years time (and beyond). Even with the best of intentions, data that has been archived for the long term remains the exception, rather than the rule. This has resulted in a myth of persistence; the incorrect assumption that once something is made openly available online, it will continue to be available. An understanding of, and commitment to, the stewardship of our digital archaeological resources for the long-term is still very much lacking.

The European Commission places international collaboration as a central tenet within most of its funding initiatives, and collaboration is the cornerstone of successful digital archaeological data stewardship. Funded by the European Commission’s Horizon 2020 research and innovation programme under Grant Agreement 823914, and implemented in parallel with SEADDA, ARIADNEplus consisted of 41 partners representing 23 countries and four international partners, working together to build a data aggregation infrastructure to serve the archaeological community worldwide, through the ARIADNE Portal ( Data-providing partners in ARIADNEplus encountered challenges in how best to map and organise their metadata in order for it to be incorporated and made discoverable within the ARIADNE Portal, but some partners encountered greater barriers than others. Barriers include lack of technical capacity in preparing their data; lack of background in data stewardship; and lack of an appropriate, persistent repository to house their data. The current development phase of the ARIADNE Portal has recently come to a close, but collaborative work continues and preparations are already underway for the next phase. This will include finding new data providing partners, expanding current collaborations, and enhancing data reuse, but with the added understanding derived from SEADDA around the importance of capacity building for data persistence which has also been an entry point for early career researchers and researchers working outside of academia.

This session invites papers from ARIADNEplus partners and SEADDA members to share their progress in capacity building in their country and/or region, as we seek to raise the visibility of data persistence within the CAA community. This session equally invites submissions from outside SEADDA and ARIADNEplus that discuss issues around data persistence, preservation, stewardship and capacity building in this area, including practical challenges, opportunities, along with ethical and theoretical considerations, such as where individual researchers, who are always pushed to prioritise innovation over preservation in their work, stand in this debate.

S43. Synergies in 3D Spatial Analysis

Gary Nobles, Oxford Archaeology
Alexander Jansen, Durham University
James Taylor, University of York
Markos Katsianis, University of Patras

Session type: Standard & Lightning talks

The purpose of this session is to bring together researchers who are combining the diverse archaeological fields with 3D spatial analysis. This will mark the 3rd and final explorative session into the application of 3D Spatial Analysis across the archaeological discipline facilitated through the CAA’s Special Interest Group in 3D Spatial Analysis. While not essential, we would appreciate speakers to consider how their thematic area of expertise (e.g. lithics, ceramics, A-DNA, botany, zoology, chemical (phosphate) etc.) or other analytical area combine in 3D space and how the benefits of analysis in 3D space can help to develop the greater narrative. We continue to ask the fundamental questions: – What do 3D and 2.5D approaches afford us beyond traditional 2D perspectives, with innovations in 3D spatial analysis continuing? – Why do we, as archaeologists, want to apply 3D spatial analysis, how would we apply it and what questions would it help answer? – What added complexities does working in three dimensions bring, how do we make the most of them, and how do we resolve or theorise around such complexities? Papers are invited from those who are working in three dimensions from across the diverse spectrum of applications. We particularly welcome papers which bring together different aspects of archaeological analysis within 3D space. Papers should go beyond presenting methodologies involving the capture of data, by instead discussing the analysis of 3D (or 4D) datasets. Any form of 3D spatial data is welcome, papers may push the boundaries (theoretically or technologically) or be presented as position papers. Amongst others, past topics have included:

– 3D Landscape Archaeology
– 3D Excavation and Post-excavation Analysis
– 3D Material Studies (e.g. lithics, ceramics)
– Geochemical Analysis in 3D space
– Investigating Visibility/Gaze/Gesture/Mobility and Perception in 3D space
– Machine Learning/AI in 3D Space
– 3D Networks and Semantic Modelling
– 3D Analysis in Virtual Reality

Submissions from young researchers/early career researchers are particularly welcome. We want to enable researchers to discuss ideas, whether or not you have access to the best data, funding, big computer systems, or underlying technical knowledge. Such positional papers should focus on what we want to get out of 3D spatial analysis. In this aspect we encourage ‘blue-sky thinking’ particularly if the tools and capabilities are not yet in existence. Presenters can select one of two formats for their paper: papers which are more exploratory and ‘blue-sky’ in nature may prefer a 10-minute lightning talk format, while those with a more traditional structure may be better suited for a 20-minute standard format. The author(s) should specify their preference when submitting their proposal. If in doubt, contact one of the session organisers well before the paper deadline. The session will conclude with a discussion bringing together the session’s principal themes which emerge from the presented papers, and incorporating elements from the discussions of previous years. Facilitated through the 3D Spatial Analysis CAA SIG, we endeavour to keep these discussions continuing beyond the meetings at CAA International.

S44. Roads to Complexity: Technological and Quantitative Approaches to Human and Objects Connectivity

Sandro Parrinello, Università degli Studi di Pavia
Lorenzo Zamboni, Università degli Studi di Milano
Daniele Bursich, Università degli Studi di Salerno

Session type: Standard

Connectivity is how people and things relate with each other through space and time, and
roads are a primal and widespread human strategy to achieve this crucial goal in evolutionary
and historical terms.
A road is a hinge between individuals and cultures, along the road events happen, stories
intertwine, goods are exchanged and cultural processes spread leading to the nourishing of
communities and territories. Both as trails or engineering works, roads usually depart from
given ‘centers’ to reach remote territories, creating new paths for interaction and cultural
The analysis of connectivity and its material signs is a common research topic in the current
archaeological agenda, with several case studies showing the degree of human-things
entanglement. However, understanding past movements requires a shift from traditional
archaeological ontologies, grounded in fieldwork and descriptive studies, towards more
analytical-based studies.
Moreover, the landscape along a road is constantly changing, in synergy (or in contrast) with
other natural and human features and leading to endless potential variations over time. There
are therefore many types of roads embedded in urban, rural or even deserted landscapes,
connecting territories through several modes and tempos of mobility.

The street is the privileged place for the movement of human society that moves through the
cities. But also from city to city, from settlement to settlement. Within the public and private
spaces intended for movement and mobility, human relationships flourish. These are the
places where knowledge is born: here are new practices such as barter which then turns into
commerce, the traffic and movement of goods, as well as the spread of art, which is
contaminated through social relations (Greek potters for example).

There are also peoples based on movement, such as the caravan cities, which trade goods
from the Far East, becoming the privileged places for markets and street vendors who move
from one continent to another. As well as trade motivated by religion, which is a very strong
reason for cultural influence, both in settled populations and in nomadic ones by vocation.

The road / path / trail is also the privileged place for the pilgrim who moves from one
religious place to another.

The streets have also constituted international commercial networks since the Bronze Age,
the privileged dimension for the breeding of cattle through mountain paths, the
standardization and the new invention of Roman roads, which constitute one of the success
factors of the Roman empire, up to intangible paths such as the aboriginal “ways of songs”.

This session welcomes papers dealing with human connectivity and objects mobility through
the application of new technologies and state-of-the-art methods. Any type of connectivity
and any category of infrastructures could be explored, including: physical and immaterial
pathways, road construction techniques and maintenance, the archaeology of roads and
streets in urban and landscape context. More specifically, we want to explore how road architecture could have influenced common and transit spaces, which agency do roads have
in cultural and socio-economic terms.
These investigations are increasingly characterised by digital technologies (network analysis,
big data, surveys, space syntax, and so on), which allows us to promote reconstructions,
hypotheses and simulations, adding greater descriptiveness and coherence to the research
synthesis process.

We also encourage the submission of papers dealing with geospatial and statistical analysis,
network analysis, and of course reconstruction of sections of routes with innovative and
immersive technologies.

Acquiring, viewing and disseminating data through dynamic databases therefore produces a
shift from traditional methods of recording information, promoting new ways of using
