The rapid increasing of similar Web services in the Internet, as well as enhancements of requirements for quality of service (QoS) by users, had created great challenges for Web service composition. We propose an optimized method for Web service composition on the basis of semantic Web. Web service is described by fuzzy Horn clause, and a QoS-oriented Web service composition model is built by fuzzy Petri Net. Based on the proposed model and semantic Web, an optimized Web service composition algorithm is introduced. An example of Web service composition is presented to illustrate that the proposed model is beneficial to both building and execution of web service composition.
