Context Aware Semantic Web Services Description and Match

First current semantic description languages which include OWL-S, WSDL-S and WSMO are introduced and compared in this paper. Then the importance of the context for service description(especially for a service requester) is analyzed. Based on the analysis we propose a new semantic service description ontology which aware context about a service request. The match chart between requested service and provided service with context description is concluded. Case study and applications in travel community show the effectiveness of this description and match in services discovery.
