Abstract: The authors define an event and an event class, and illustrate the relations between event classes. Then event-oriented ontology model is constructed, which will contribute new methods and technologies to semantic-based knowledge processing. Furthermore, taking event class ranking as an example based on event ontology, the method of HARank-based event class ranking is introduced for event ontology, and corresponding experimental and evaluating results are presented. In comparison with conventional methods, event ontology represents knowledge with a higher granularity, and it will be more suitable for the representation of the knowledge about the movement and state changes in the real world.

Key words: event, event class, event class relation, event ontology, event class ranking
