Abstract

This paper establishes WSVE process model as the object of analysis and discovers functional and non-functional QoS demands of WEB service. On the basis of these demands, the paper suggests service discovery algorithms for service and QoS. On the basis of the service discovery, it puts forward the method for transforming process model into BPEL4WS. It achieves the integration of virtual enterprise through WEB service composition and comes up with the idea for dynamic service composition which is driven by information.
