We face the issue of formally modeling roles in the semantic representation of events: we propose a distinction between thematic roles and social roles, and we show that they have important ontological differences, suggesting distinct formal representations. We apply our approach in the context of the Harlock'900 project, including the definition of thematic roles as binary properties in the HERO ontology.

Abstract
We face the issue of formally modeling roles in the semantic representation of events: we propose a distinction between thematic roles and social roles, and we show that they have important ontological differences, suggesting distinct formal representations. We apply our approach in the context of the Harlock'900 project, including the definition of thematic roles as binary properties in the HERO ontology.
