A Method for Semantic Web Service Discovery Based on Context Inference

Abstract

Constrained by the context around user, the service discovery result mostly does not fulfill the context expectation of user′s when we apply traditional semantic Web service discovery method. An approach for Web service discovery based on context and inference rules is proposed in the paper. The result of Web service discovery will fulfill the user′s context in this way. The user context ontology and Web service context ontology are proposed respectively to describe context information. And the inference meta-rules between user context and service context are proposed as the foundation to refine results of Web service discovery. The context inference algorithm is proposed and implemented in the context inference module finally. Comparing to existing approach for semantic Web service discovery, it is proved by the experiment that the more appropriate result of Web service discovery will be obtained for the user while reasonable time cost is added.
