CCS'16 Satellite Workshop

Computational Social Science

Contagion, Collective Behaviour, and Networks

21 September 2016

Amsterdam,The Netherlands


Technology-mediated social collectives are taking an important role in the design of social structures. Yet our understanding of the complex mechanisms governing networks and collective behaviour is still deplorably shallow. Fundamental concepts of on- and off-line networks such as power, authority, leader-follower dynamics, consensus emergence, information sharing, conflict, and collaboration are still not well defined and investigated. These are all crucial to illuminate the advantages and pitfalls of collective decision-making, which can cancel out individual mistakes, but also spiral out of control.

In recent endeavours, data from Twitter, Facebook, Google+, Wikipedia, and weblogs have been shown to strongly correlate to, and even predict, elections, opinions, attitudes, movie revenues, and oscillations in the stock market, to cite few examples. Similar data provided insights into the mechanisms driving the formation of groups of interests, topical communities, and the evolution of social networks. They also have been used to study polarization phenomena in politics, diffusion of information, and the dynamics of collective attention. However, a deeper understanding of these phenomena is still very much on demand. In parallel, and even preceding the surge in interest towards social media, the area of agent-based modeling (ABM) has grown in scope, focus and capability to produce testable hypotheses, going beyond the original goal of explaining macroscopic behaviors from simple interaction rules among stylized agents.

The aim of this satellite is to address the question of ICT-mediated social phenomena emerging over multiple scales, ranging from the interactions of individuals to the emergence of self-organized global movements. We would like to gather researchers from different disciplines and methodological backgrounds to form a forum to discuss ideas, research questions, recent results, and future challenges in this emerging area of research and public interest. Particular attention will be devoted to the following topics:

  • Interdependent social contagion process
  • Peer production and mass collaboration
  • Temporally evolving networks and dynamics of social contagion
  • Cognitive aspects of belief formation and revision
  • Online communication and information diffusion
  • Viral propagation in online social network
  • Crowd-sourcing; herding behaviour vs. wisdom of crowds
  • E-democracy and online government-citizen interaction
  • Online socio-political mobilizations
  • Public attention and popularity
  • Temporal and geographical patterns of information diffusion
  • User-information interplay
  • Group formation, evolution and group behavior analysis.
  • Modeling, tracking and forecasting dynamic groups in social media.
  • Community detection and dynamic community structure analysis.
  • Social simulation, cultural, opinion, and normative dynamics.
  • Empirical calibration and validation of agent-based social models.
  • Models of social capital, collective action, social movements.
  • Coevolution of network and behavior.


Submissions will be made by sending one A4 page abstract in pdf via Easychair. The deadline for abstract submission is 20th June 2016. The contributions to the event will be evaluated by the programme committee through a peer review process that will account for the scientific quality as well as for the relevance of the contribution to the aims of the satellite. The authors of accepted abstracts will be notified via e-mail by 27th June 2016.


All the participants of the satellite meeting (with or without abstract submission) must register for the Conference on Complex Systems 2016. The Early Bird registration deadline is 30th June 2016.
