Come to our networks session and workshop at CAA2015 in Siena!

caaWe would like to bring a session on archaeological network science at the 2015 Computer Applications and Quantitative Methods in Archaeology (CAA) meeting in Siena (Italy) to your attention. We welcome papers describing archaeological applications of network science, with a particular focus on the treatment of space and time in these applications. Please find the abstract below for more details. The call for papers for CAA2015 is now open, the submission deadline is 20 November 2014. The full list of CAA2015 sessions can be viewed here. Papers can be submitted here.
We will also host a practical workshop at CAA2015: Introduction to exploratory network analysis for archaeologists using Visone (abstract below). Registration for this workshop will open at a later date.

Geographical and temporal network science in archaeology

Tom Brughmans and Daniel Weidele

Formal network techniques are becoming an increasingly common addition to the archaeologist’s methodological toolbox. Archaeologists have adopted these techniques mainly from the fields of social network analysis, physics and mathematics, where they have been developed and applied for decades. However, network science techniques for the analysis or visualisation of geographical and long-term temporal phenomena have seen far less development than those for social and technological phenomena. Conversely, archaeology has a long tradition of studying long-term change of socio-cultural systems and spatial phenomena, a research focus and tradition that is a direct consequence of the nature of archaeological data and our ambition to use it as proxy evidence for past human behaviour. We believe this spatial and temporal research focus so common in archaeology could inspire the development of innovative spatial and temporal network science techniques.
This session welcomes archaeological applications of formal network science techniques. It particularly encourages elaboration on the geographical and temporal aspects of applications. What are the implications of working on large time-scales for the use of network science techniques and the interpretation of their outputs? How can the study of long-term change of social systems inspire the development of innovative network science techniques? What advantages do geographical network approaches offer over other spatial analysis techniques in archaeology? How can the long tradition of studying spatial phenomena in archaeology inspire the development of innovative network science techniques?

Introduction to exploratory network analysis for archaeologists using Visone

Daniel Weidele and Tom Brughmans

Network science techniques offer archaeologists the ability to manage, visualise, and analyse network data. Within different archaeological research contexts, network data can be used to represent hypothesised past social networks, geographically embedded networks like roads and rivers, the similarity of site assemblages, and much more.
A large number of software programs is available to work with network data. Visone is one of them and offers a number of advantages:
• Free to use for research purposes
• A user-friendly interactive graphical user interface
• Innovative network visualisations
• Exporting publication-quality raster and vector files
• The incorporation of statistical modelling techniques
This workshop introduces the basics of network data management, visualisation and analysis with Visone through practical examples using archaeological research questions and datasets. The workshop is aimed at archaeologists with no required previous experience with network science.
Participants should bring a laptop with Visone installed (download Visone: http://visone.info/ )
Maximum 20 participants.

Session 5L: Modelling large-scale human dispersals: data, pattern and process

Archaeology has largely moved forward from the simplistic ‘dots-on-the-map’ and ‘arrows-on-the-map’ approaches when it comes to studying large-scale human movements. Current models regarding spatio-temporal distribution and migration of humans often highlight the complex nature of such phenomena and the limitations that any particular data type impose on the reconstruction, be it environmental (paleoclimate, paleotopography, paleofauna and -flora), archaeological (site distribution, patterns in material culture) and other types of data (genetics, isotopes etc). Similarly the, often very coarse, resolution of the data coupled with the difficulty of integrating different types of information within one framework make the task of researching large-scale human dispersal challenging. Nevertheless, a number of recent applications employing different computational techniques show that this can be achieved. From the data acquisition, cataloguing and storing, to spatial analysis and identifying patterns and distributions in the data to building abstract and semi-realistic simulations of the processes behind the dispersals, computational techniques can aid the process of investigating human movement on various scales and allow researchers to tackle the underlying complexity of the studied systems moving the debate beyond simple intuitive models.

This session aims to summarise the recent progress in the topic, discuss major challenges and provide a base for establishing further directions of research. We invite contributions from researchers studying human movements on the meso- and macro-scale and employing any of the wide variety of techniques and theoretical frameworks within the following three themes:

DATA: spatio-temporal data acquisition and integration (for example, data types, quantifying uncertainty and biases of the data, large-scale databases, cross-platform integration);

PATTERN: spatio-temporal analysis and modelling (statistical modelling, GIS, C14 among others);

PROCESS: modelling of processes and mechanisms underpinning dispersal through simulation (agent-based and equation-based modelling, cellular automata, system-dynamics modelling, (social) network theory) and other techniques.

Workshop 8: First steps in agent-based modelling with Netlogo

Following on the success of the simulation workshops at CAA2012 in Perth and CAA2013 in Paris, we would like to continue the beginner course in NetLogo – an open-source platform for building agent-based models. NetLogo’s user-friendly interface, simple coding language and a vast library of model examples makes it an ideal starting point for entry-level modellers, as well as a useful prototyping tool for more experienced programmers. The first part of the workshop will be devoted to demonstrating the basics of modelling with NetLogo through a set of worked examples. This should give each participant enough skills and confidence to tackle the second exercise: building an archaeologically-inspired simulation in a small group. Finally, the last two hours will consist of a ‘drop-in’ clinic for anyone who would like to discuss their ideas for a simulation, needs help developing a model, or would like direction to further resources for modellers.

No prior knowledge of coding is required but we will ask the participants to bring their own laptop and install NetLogo beforehand: https://ccl.northwestern.edu/netlogo/

Roundtable 5: Simulating the Past: Complex Systems Simulation in Archaeology

In the last few years approaches commonly classified as computational modelling (agent-based and equation-based modelling, and other types of simulation etc.) are becoming increasingly common and popular among the archaeological computing community. Almost all research activity could be termed ‘modelling’ in some sense, for example, in archaeology we create conceptual models (hypotheses, typologies), spatial models (GIS), virtual models (3D reconstructions) or statistical models to name but a few. Most of them, however, investigate either the elements of the system (individual pots, skeletons, buildings etc.) or the pattern produced by the system elements (cultural similarities, settlement distribution, urban development etc.) and only theorize about the possible processes that led from the aggregated actions of individual actors to population-level patterns. In contrast, simulation allows us to approach such processes in a formal way and tackle some of the past complexities. It helps us to create ‘virtual labs’ in which we can test and contrast different hypotheses, find irregularities in the data or identify new factors which we would not suspect of having a significant impact on the system. In short, complexity science techniques have great potential for diverse applications in archaeology and may become a driving force for formalisation of descriptive models for the whole discipline.

The aim of this roundtable is to discuss the potential and challenges of complex systems simulation, including but not restricted to:
the epistemology of computational modelling (what it can and cannot do);
data integration and its use for model validation;
system formalisation and the role of domain specialists;
replicability and reuse of code;
lessons learnt from other disciplines commonly using simulation (ecology, social science, economics etc.)
communication between modellers and the wider archaeological public;
further directions of research.

Finally, we would like to take this opportunity to propose the creation of a new Special Interest Group (SIG) under the auspices of CAA (named: ‘CAA Complex Systems Simulation SIG’), and to discuss a preliminary plan of the proposed activities of the SIG and an outline of how the SIG is to be organised.

HNR workshop Bochum

bochumLast month’s Historical Network Research conference in Ghent was awesome! Can’t get enough of that networky goodness? Then you might be interested in the next event in the HNR series: “Vom Schürfen und Knüpfen – Text Mining und Netzwerkanalyse für Historiker_innen”, 10-12 April 2015 in Bochum. More info below.

HNR Workshop 2015

Vom Schürfen und Knüpfen – Text Mining und Netzwerkanalyse für Historiker_innen 10.–12. April 2015
Als 9. Veranstaltung in der Reihe „Historische Netzwerkforschung“ findet im April 2015 ein Workshop zu semantisch-sozialen Netzwerken an der Ruhr-Universität Bochum statt. Die Workshop-Reihe bietet historisch orientierten Forscher_innen aller Fachbereich erste Einblicke in die Methodik und eine Plattform zum Austausch über die neuesten Techniken der Netzwerkanalyse. Unter dieser Zielsetzung wird sich der Bochumer Workshop mit der Methode des Text Mining beschäftigen, die eine zunehmende Automatisierung der Erstellung von Netzwerken aus historischem Material ermöglicht. Darüber hinaus spielt die Frage nach den Dimensionen von Texten, die durch diese Methoden repräsentiert werden können, eine Rolle. Hierbei bieten semantisch-soziale Netzwerke die Möglichkeit, sich zum einen mit Begriffszusammenhängen und Konzeptualisierungen, zum anderen mit Beziehungen zwischen Entitäten auseinanderzusetzen.

Der Workshop soll auch Teilnehmer_innen ohne Vorkenntnisse zeigen, wie Relationen von Worten und/oder Entitäten aus einem Text mithilfe von computergestützten Verfahren erzeugt und graphisch abgebildet werden können, ohne dass sie zunächst manuell (beispielsweise in einer Tabelle) erfasst werden müssen.

Am Freitagvormittag besteht die Möglichkeit, vor der offiziellen Eröffnung des Workshops, an einer Einführung in die Programmiersprachen Python und/oder R teilzunehmen. Während des Workshops gibt es eine mehrstündige Session zum Visualisierungsprogramm Gephi.

Darüber hinaus sollen die Teilnehmer_innen erste Einblicke in die folgenden Bereiche bekommen:

Eigenschaften, die ein Text besitzen sollte, um ein Netzwerk erstellen zu können
Möglichkeiten, die es zur Verbesserung der Qualität von Netzwerken gibt
Tools und Computerprogramme, die bei der Erstellung von Netzwerken helfen können
Fragestellungen, die durch die semantisch-soziale Netzwerkanalyse beantwortet werden können
Auf diese Weise soll gezeigt werden, wie man einen Text zunächst „schürft“, um schließlich ein Netzwerk zu „knüpfen“.
