Event class is an abstract event that represents a set of events with some common features. There are inherent relations among event classes. Event classes and their relations are the important parts of event knowledge base. We gave a novel framework to represent event class semantic by marriage Neo-Davidsonian event semantic and 6-element event class model. The framework treated the predicate of event class as unary predicate with event class argument ec only. It connected the predicate and the other elements of event class with connecting symbol ⁁. And the framework can’t only represent the taxonomic relations among event classes, but also respectively represent non-taxonomic relations via the connecting symbols ⊄, ⊳, →, ∥ and ⊒. The representation examples indicate the novel framework can represent event classes semantic and different kinds of relations among event classes.
