Matching and Discovery Research of the Semantic Web Service Based on the Concept Lattice

With the development and application of Web service technology, the semantic web service which has the ability of the high recall and precision have become a research focus. And how to match efficiently and find the services meeting the needs of users´ requisiton are the basis of service composition. By analyzing the characteristics of semantic Web service, this paper presents the semantic service concept lattice based on semantic Web service and also uses classified information to carry out the classification management of service, and give semantic Web service lattice´ construction, update, and search algorithm. The experiment results show that the efficiency of searching service and the efficiency of maintaining service are both improved greatly in this model.
