The Research of Composing Semantic Workflow Engine Based on Web Service

Web service is one of SOA applications in the Internet. Web service workflow is a set of Web services that are executed in some sequence. In this way, it will greatly improve the reuse of Web Services. As well as to enhance reuse of workflow, this paper describes, finds and composes workflow by ontology. And adds a translator from the Owl-S of workflow to BPEL4WS on the base of traditional workflow engine. Thus it not only retains the main structure of the tradition workflow engine, but also achieves the composing of semantic workflow.
