Capturing group interactions: The next frontier of modeling social and biological systems — •Frank Schweitzer — Chair of Systems Design, ETH Zürich, Switzerland

Complex social and biological systems comprised of many interacting agents are often represented as networks. This implies to decompose interactions between many agents into concurrent dyadic interactions of pairs of agents. Such a reduction is recently challenged with different approaches, which are addressed in this talk: (i) temporal network models reflect the causal relation between interactions occuring at different time steps, (ii) hyperedge network models capture group interactions by constructing higher-order networks, (iii) inference network models reveal information hidden behind observed interaction patterns. Combined, we obtain a very rich picture of social structures that emerge and adapt at different time scales and at different size levels (dyads, groups, communities, networks). Two examples of real-world social organizations (Bechstein bats, software developers) are used to illustrate our insights.
