Logic programming with social features

In everyday life it happens that a person has to reason about what other people think and how they behave, in order to achieve his goals. In other words, an individual may be required to adapt his behaviour by reasoning about the others’ mental state. In this paper we focus on a knowledge representation language derived from logic programming which both supports the representation of mental states of individual communities and provides each with the capability of reasoning about others’ mental states and acting accordingly. The proposed semantics is shown to be translatable into stable model semantics of logic programs with aggregates. To appear in Theory and Practice of Logic Programming (TPLP).
