Title: Gatekeepers in Social Networks: Logics for Communicative Actions.
Abstract. Information control has been the subject of investigation in the fields of information theory and social network analysis. Gatekeepers play a central role, as they are the agents that can manipulate the information flow between groups of agents. In this talk, we present a model that captures the essential properties of gatekeepers in a social network. Firstly, we use graph theory to explore the structural dimension of gatekeepers. Secondly, we use notions from Dynamic Epistemic Logic and Coalition Logic to model the dynamics of their informational capabilities. We find that gatekeepers can be categorized into three distinct subclasses, which differ in terms of their structural properties or type of information control.
This talk is based on the work I did with Alexandru Baltag for my MSc thesis.
Hope to see you there!
