| Outline of Final Research Achievements |
Daily, people share their opinions over social media. In particular, negative content regarding a brand could propagate rapidly and generate negative perceptions. So one needs to understand and monitor the public perception and the social reputation of companies. The "Belief Revision Games" (BRG) framework was introduced in 2015 for modeling such situations. This project aimed to enrich the BRG framework by providing a set of formal concepts to be integrated to it: (1) we explained what kind of revision policies the agents use, assuming that they revise their beliefs in a "rational" way; (2) we explained how an agent can be "manipulated", so as to convince all agents in the network of some "goal information" to be disseminated; (3) we introduced algorithms to simulate opinion propagation in a BRG.
