Research on Event Network Model and Its Application

According to the result analysis of events,an event network model is proposed.The event network is a new know ledge representation model with the event unit and concept unit,which can describe the movements and changes in the real world.An event unit is made up of a number of concept role units through semantic relations.Because of partial order between the properties of the concept unit of each role,the concept hierarchies can be generated.Every concept hierarchy can be represented by a resource concept lattice.Therefore,the event network can be formalized by employing multi resource concept lattices.Because the event unit is embodied by event individual and event class,and the concept unit is embodied by entity individual and entity class,the event network as a nucleus will be mapped to event ontology through the mapping rules.The event ontology with event class added is a new type of ontology which is extended on the basis of the traditional concept ontology with entity class.A retrieval system for event knowledge is implemented by employing event ontology.The experiments show that the event network model is feasible and effective.
