An agent-based web service workflow model is presented in this paper to facilitate the autonomic Web service composition, which contains three layers. The top is the user layer which represents the service requirements as goal workflow, the bottom service layer denotes the distributed Web services, and the middle is the agent layer. Each service agent in the agent layer abstracts the features of a group of actual operations with similar functions as operation template and models the process of using operation templates to achieve a certain goal as plan. The proposed model has great flexibility and extensibility and provides the guidance for the development of Web service integration tools.
