Do individuals who make up communities like each other or not? Are they friends or enemies? The answers to these questions are critical to understanding people's behavior. Positive and negative relationships affect both who people interact with and who they avoid. Moreover, people adapt to patterns of positive and negative relationships, and their adaptation can cause communities to segregate and polarize. Despite the importance of these relationships, data on them are missing or limited to small communities and short time periods.

During the faculty seminar, Dr. Giacomo Vaccario from ETH Zürich will present conclusions from the observation of interactions in pairs - communication via mobile phones or face-to-face contacts. The method is based on a set of networks that can be analyzed.

Dr. Giacomo Vaccario along with other members of the group of prof. Schweitzer from Zurich cooperates with the Laboratory of Physics in Economics and Social Sciences as part of the bilateral NCN project Alphorn Signed Relations and Structural Balance in Complex Systems: From Data to Models. The main objectives of the project include the analysis of signed network models, i.e. networks in which the interactions of connecting agents are assigned a positive or negative sign. Thanks to this approach, relationships occurring in social networks are reproduced more accurately. In the project, the models built concern both the consequences of the existence of a network with a sign, i.e. different behavior of agents connected with a positive and negative edge, and the evolution of such a network itself.
