Event as the unit of human knowledge, has attracted more and more attention and high regards from the academia. Events-based knowledge extraction and representation extend concept-based knowledge process techniques largely. In order to represent event-based knowledge, this paper extends existing web ontology language, OWL, by introducing some new constructors and axioms related to event features. This paper firstly gives definitions about event and event relationships, and then proposes an Event-based Description Logic, EDL, as logic basic of extended OWL. The semantics of event constructors and axioms can be mapped to EDL. In the end, we give an event class description which shows that event-based knowledge can be expressed well in the extended OWL language.
