A contextual framework for reasoning on events

In this paper we investigate the contextualized representation of events. In particular, we re-interpret the formalization of events and situations adopted in the NewsReader Event and Situation Ontology (ESO) according to the notions of context and module proposed in the Contextualized Knowledge Repositories (CKR) framework. This contextualized formalization sets the basis for exploiting logical reasoning on events and situations, enabling to automatize tasks such as: recognizing incompatible event descriptions or inconsistent situations, inferring missing or implicit events.
