Archaeological network research: formal network representation of archaeological theories
Paula Gheorghiade (Department of Art, University of Toronto)
Tom Brughmans (School of Archaeology, University of Oxford)
In this session we aim to discuss and encourage the explicit representation of archaeological theories as network data, and the explicit theoretical motivation of network science method selection.
Formal network science methods are increasingly commonly applied in archaeological research to study diverse aspects of past human behaviour. The vast majority of these applications concern the use of exploratory network analysis techniques to study the structure of a network representation of an archaeological dataset, which often lead to a better insight into the structure of the dataset, help identify issues or missing data, and highlight interesting or surprising data patterning.
Less common is the explicitly formulated theoretical motivation of exploratory network analysis tool selection. What tools are appropriate representations of my theorized assumptions? What tools violate my theoretical framework? Equally uncommon is the formal representation of archaeological theories (rather than archaeological data) as network data. What network data pattern do I expect to see as the outcome of a theorized process? What does a theorized past relational phenomenon look like in network terms?
Taking explicitly formulated theories rather than datasets as the starting point of archaeological network research is useful for a number of reasons. It forces the researcher to specify the theory that will enable its formal representation, and possibly improve or modify it through this process. It allows for understanding the behaviour and data predictions of a theory: in exploring the structure of the theorized relationships, the implications for processes taking place on theorized networks, and the evolution of theorized network structure. It facilitates the selection of appropriate network analytical tools that best express the theory or that are appropriate in light of the assumptions inherent in the theory. Finally, it allows for comparisons of data patterns simulated as the outcome of a theorized network process with archaeological observations, to evaluate the plausibility of the theory.
This session welcomes presentations on the following topics:
• Archaeological network research: applications, methods or theories
• Network representation of archaeological theories
• Testing archaeological theories with network science
• Using network configurations, motifs and graphlets for representing theories
• Exponential random graph modelling
• Agent-based network modelling
• Spatial network modelling

Session 7: Mediterranean Connections – how the Sea links people and transforms identities

Session organizers: A. Rutter*, E. Loitzou, O. Nakoinz, F. Fulminante, L. Schmidt*, D. Möhlmann, L. Käppel, H. Klinkott

*corresponding chair, stu213017[at]mail.uni-kiel.de, lschmidt[at]email.uni-kiel.de

Keynote speaker: tba

Long-term research interest in the Mediterranean has produced a substantial body of data and concepts that make it a fascinating testing ground for new approaches on identity, alterity, and connectivity. For the inhabitants of the Mediterranean, the sea evidently influenced their lives and their thinking in a significant way. (Pre-)history, philology, and archaeology alike can trace the emergence of ancient perceptions of distance and connections as well as the movement of material, people, and ideas. Researchers of these professions have long been irritated by a tendency to define political or cultural entities spatially. The identification of collective identities as networked spheres of interest, however, allows us to progress towards an understanding of processes within the Mediterranean as a dynamic area of common cultures and conflicts. Shared mental maps and networks thus help to understand the collapse of powers, systems, and identities, the emergence of new ones, and the role of possibly persisting parts of a network in such processes.

With contributors from all disciplines dealing with connections, networks, and mental maps, whether they be archaeology, (pre-)history, philology, geography, and sociology, and also the natural sciences, we would like to discuss the following:

  • how the contact area of the Mediterranean influences the (self-)representation of peoples and individuals as well as the formation of identity and alterity
  • what role Mediterranean connections play in cultural, political, and ideological developments
  • how ancient writers and artists form and use Mediterranean connections
  • analyses of the emergence and transformations of connections within the Ancient Mediterranean
  • the conditions under which the physical environment determines the presence or absence of connections
  • how the concept of network layers contributes to an understanding of past events around the Mediterranean seascape
  • new theories and interpretations concerning the role of power, conflicts, and different communities that can be connected to the network approach
  • network modelling between simulations and empirical observations

We particularly invite contributions from a wide range of regions to include as many perspectives as possible from around the Mediterranean World.

The network aspects of this session links with the theoretical approaches of Complexity (Schlicht et al., Session 6), while connectivity and emergence of identity relate to Social Space (Grimm et al., Session 1) and Social Resilience (Yang et al., Session 11). They also form a backdrop to considerations of Territoriality (Schaefer-Di Maida et al., Session 8). The concept of mental maps is also reflected in Urban Knowledge (Chiarenza et al., Session 9).

Let’s do networks AND theory!

I sometimes get a bit annoyed that fellow archaeologists assume I don’t do theory because I use calculators. In fact, network science and all archaeological research is completely useless unless it is explicitly theoretically informed, and I have published this argument loads. Yet I notice that it is rather rare for the theories that archaeologists formulate about relationships to be explicitly recorded in their papers alongside their network analysis results.
So let’s try to change this: here’s a call to be explicit about our theoretical frameworks when doing archaeological network research. This is the topic of a session I co-chair with Paula Gheorghiade at the CAA in Krakow 2019.

Agents, networks and models: formal approaches to systems, relationships and change in archaeology

Tom Brughmans

Benjamin Davies
University of Auckland, New Zealand

Even if much ink has already been spilled on the need to use formal, computational methods to represent theories, compare alternative hypotheses and develop more complex narratives, the idea is still far from being firmly established in archaeology.

Complexity Science, the study of systems consisting of a collection of interconnected relationships and parts, provides a useful framework for formalising social and socio-natural models and it is often under this umbrella term that formal models are presented in archaeology. It has a particular appeal for researchers concerned with humans, as it stresses the importance of individual actions and interactions, as well as relations between individuals and wider system elements. Archaeology is a discipline that studies long-term, large-scale shifts in social change, human evolution, and relationships with the environment; how these phenomena emerge through the actions and interactions of individuals are questions that lie at the heart of our interests. Complexity Science offers an arsenal of methods that were developed specifically to tackle these kind of mulitscalar, multifaceted research questions.

This session will provide a forum for archaeological case studies developed using Complexity Science toolkits as well as for more methodological papers. We invite submissions of models at any stage of development from the first formalisation of the conceptual model to presenting final results.

Possible topics include but are not limited to applications or discussions of the following approaches:

  • Complexity science,
  • Network science,
  • Agent-based and equation-based modelling,
  • System dynamics,
  • Long-term change in social systems,
  • Social simulation in geographical space,
  • Complex urban systems, space syntax, gravity models.

Final discussion

Workshop in Ottawa tomorrow

networks-simulation-workshop-imageIza Romanowska and I have spent the last few weeks at Carleton University in Ottawa, Canada, doing some awesome Roman networky boardgame “research” with Shawn Graham. You’ll hear more about this cool work soon. Tomorrow we will give a workshop on simulation and networks for the humanities. If you happen to be in the neighbourhood, swing by! If not, get in touch if you are interested and I will share the workshop tutorials with you.

Carleton University, Ottawa, Macodrum Library Discovery Centre RM 481, 11 – 2

networks-simulation-workshop-imageUnderstanding the complexity of past and present societies is a challenge across the humanities. Simulation and network science provide computational tools for confronting these problems. This workshop will provide a hands-on introduction to two popular techniques, agent based modeling and social network analysis. The workshop has been designed with humanities students in mind, so no prior computer experience required.

The workshop is led by Tom Brughmans and Iza Romanowska of University of Konstanz and the University of Southampton, two of the leading digital archaeologists. Brughmans is co-editor of the recent volume, ‘The Connected Past: Challenges to Network Studies in Archaeology and History‘ published by Oxford University Press. Romanowska edits the scholarly blog ‘Simulating Complexity‘ and is a Fellow of the Software Sustainability Institute where she promotes the use of computational methods in the humanities.

Love sampling, stats and networks? (really?) Present at our CAA 2017 session in Atlanta!

caaThe CAA call for papers and posters is now open until 28 October! The full list of sessions is published here. Among them you will notice a most awesomely appealing title: “Archaeological Networks: Uncertainty, Missing Data, and Statistical Inference”. Fancy nerding out on networks, stats and sampling? Then present a paper in the session Matt Peeples and myself will chair.

Archaeological Networks: Uncertainty, Missing Data, and Statistical Inference

Empirical studies of networks based on archaeological data are on a rapid rise. So far, the adoption of network methods from other fields has outpaced the development of new techniques and heuristics for dealing with the sometimes peculiar qualities of archaeological network data. Key among the issues faced by archaeologists interested in using networks are the impact of uncertainty and missing data on the properties of the networks we generate. We often must build networks based on an incomplete universe of nodes (because our units of analysis lack current archaeological information or have been destroyed) as well as incomplete information about the nodes we do have (due to sampling issues, different recording conventions, etc.). Further, we often have no consistent way to estimate how much information we are missing. The prevalence of such known unknowns and unknown unknowns suggest that we must carefully temper inferences drawn from networks defined using archaeological data. Importantly, all hope is not lost and these challenges are not unique to archaeology or network data alone. In this session, we ask contributors to explore the potential impact of missing data on empirical archaeological networks and/or test tools and approaches for identifying robust patterns in archaeological networks despite such challenges. Approaches may include, for example, the use of probabilistic estimates and sensitivity analysis already popular in many other areas of archaeological statistical analysis such as seriation or methods specific to network data drawing on the large body of research focused on estimating the shape and properties of so called “dark” networks (common in studies of covert organizations, epidemiology, and infectious disease). In addition, this session welcomes archaeological applications of network methods in general.

Linking ancient people, places, objects and texts

snapThe following round table discussion event (see below) might be of interest to readers of this blog (it is definitely of interest to me!). I believe it will give us an insight into the direction the SNAP:DRGN project (which I blogged about earlier) is heading, and possibly an opportunity to contribute to their brainwave. Although the project focuses on linked open data, networks are definitely among their research interests, and the relation between network science and linked open data can always do with some more discussion. New technologies have a place in our workflows, we just need to find it! Linked open data and networks often accompany each other in project descriptions, but the usefulness of pairing them up beyond a metaphorical use of these new technologies needs more critical discussion. This round table might not necessarily be the place this needs to happen, but we will find a suitable venue for this discussion at some point 🙂

As classicists and ancient historians have become increasingly reliant on large online research tools over recent years, it has become ever more imperative to find ways of integrating those tools. Linked Open Data (LOD) has the potential to leverage both the connectivity, accessibility and universal standards of the Web, and the power, structure and semantics of relational data. This potential is being used by several scholars and projects in the area of ancient world and historical studies. The SNAP:DRGN project (snapdrgn.net) is using LOD to bring together many technically varied databases and authorities lists of ancient persons into a single virtual authority file; the Pleiades gazetteer and service projects such as Pelagios and PastPlace are creating open vocabularies for historical places and networks of references to them. Museums and other heritage institutions are at the forefront of work to encode semantic archaeological and material culture data, and projects such as Sharing Ancient Wisdoms (ancientwisdoms.ac.uk) and the Homer Multitext (homermultitext.org) are developing citation protocols and an ontology for relating texts with variants, translations and influences.

The panel will introduce some of these key projects and concepts, and then the audience will be invited to participate in open discussion of the issues and potentials of Linked Ancient World Data.
