Abstract:

To improve quality of services discovery in grid-based fault diagnosis environment, a service discovery approach based on ontology was proposed. The approach utilized ontology to describe the function characteristics of fault diagnosis, and extended ontology Web language for service(OWL-S) to realize semantic representation of grid service, and then adopted functional characteristics of fault diagnosis as matching criterion to establish semantic matching mechanism. A semantic information service component of fault diagnosis according to the approach had been successfully applied to the grid-based fault diagnosis system.
