Abstract:

Many different grid services are distributed in dynamic grid computing environments. The key factors affecting the performance of grid computing is to  perform grid service discovery quickly and accurately. The paper proposes an ontology-based and agent-based grid service discovery mechanism which feat  ures good expansibility and integrity. The model a- dopts the agent technique to search services, and different agents provide different ontology knowle dge bases of different virtual organizations. In addition, it uses the semantics of ontology to finish service matching, and achieves an intelligent ser  vice discovery.

Key words: ontology, agent, grid service, service discovery
