Research on Service Discovery and Matching Based on Ontology and Service Capabilities in Manufacturing Grid

In manufacturing grid (MG), manufacturing service discovery and matching are related to the realization of the goal of manufacturing resource sharing. Because of lacking the support of a powerful semantic model, the methods and effects of service discovery and matching are still non-ideal, and affect the implementation of rapid, effective discovery and matching of the manufacturing service. On the basis of analyzing the deficiencies of service discovery mechanisms of the current Web service, and the problems of service discovery and matching in MG, the paper propose that the matching of service capabilities are the basic requirements of service discovery and matching in MG. The model of the service discovery and matching is set up. The matching method based on OWL-S (Web ontology language for services), the matching degrees, matching rules and algorithms based on ontology and service capabilities are put forward.
