Combination existing Semantic Web services to form a new, reusable and value-added service is an important issue of the Semantic Web Services. In this paper, we proposed a message-driven-based Semantic Web Service Composition (SWSC) model, which is recognizes the semantic connection between Web Services base on Web Services Description Framework for Semantic (RDF4S), and using it modeling inner-relationship of SWSC. In this context, by defining semantic message and its processing rules, composition service can be described and executed though the messages interaction between component Services.
