Challenges in Modelling Social Conflicts: Grappling with Polysemy

This discussion paper originates from the preceding annual workshop of the Special Interest Group on Social Conflict and Social Simulation (SIG-SCSS) of the ESSA. The workshop especially focused on the need to identify and examine challenges to modeling social conflicts. It turned out that the polysemous nature of social conflicts makes it very difficult to get a grasp of their complexity. In order to deal with this complexity, various dimensions have to be taken into consideration, beginning with the question of how to identify a conflict in the first place. Other dimensions include the relation of conflict and rationality and how to include non-rational factors into conflict models. This involves a conception of organized action. Finally, guiding principles for model development are being discussed. We would like to invite readers of the Journal of Artificial Societies and Social Simulation to 'sow the seeds' of this debate.Social Conflicts, Conflict Models, Modelling Challenges, Polysemy, Rationality, Emotions

Agent Based Modelling and Simulation of Social Processes

The paper provides an introduction to agent-based modelling and simulation of social processes. Reader is introduced to the worldview underlying agent-based models, some basic terminology, basic properties of agent-based models, as well as to what one can and what cannot expect from such models, particularly when they are applied to social-scientific investigation. Special attention is given to the issues of validation.

About modelling of complex networks with applications to terrorist group modelling

Based on available data on various organisations and networks, the article explores some key properties of the structure of a terrorist organisation. Analytical focus is on lower levels of organisational hierarchy, where network structure with exponential distribution of the number of links among network nodes is clearly visible. Such networks tend to grow organically, are very efficient in information diffusion, and are robust regarding stochastic failures and targeted attacks. These network features are illustrated by recent example based on network data about September 11, 2001 attacks on New York and Washington.

An Overview of Databases on Conflicts and Political Crises

This paper provides an overview of important projects concerned with the development of databases on conflicts, crises and similar political events and those dealing with the structural characteristics of nation-states. The various databases are usually differently conceptualized, even when they describe the same phenomenon. Different conceptualization of the problem leads to distinct operational definitions, and eventually to divergent coding rules. Therefore, the researcher intending to use the existing data for statistical analysis or modelling social processes can become lost browsing the multitude of diverse datasets. In this overview, the short descriptions of important data-gathering projects include information on the institutions where the projects are placed, their principal investigators, time span and number of cases they include. Finally, all databases are classified according to their focus (event/structure) and their level (nation-state/international relations) of observation.

An Agent-Based Model of Ethnic Mobilisation

In this paper we used the methodology of agent-based modelling to help explaining why populations with very similar socio-demographic characteristics sometimes exhibit great differences in ethnic mobilisation levels during mobilisation processes. This agent-based model of ethnic mobilisation was inspired and developed by combining and extending several theories, ideas and modelling constructs that were already used in agent-based modelling of social processes. The model has been specifically adapted to account for some of the most important characteristics of ethnic mobilisation processes that took place in the former Yugoslavia. Results obtained by experimenting with the model indicate that the observed differences in mobilisation levels across populations may sometimes not be related to the variations within any particular socio-demographic factor, but merely to random differences in the initial states of the individuals. In this model these random differences primarily relate to the degrees of importance that individuals attach to their ethnic identity, as well as to the layout of social networks.Agent-Based Modelling; Ethnic Identity; Ethnic Mobilisation
