摘要

Automatic discovery and composition of Web services is an important research area in Web service technology, in which the specification of Web services is a key issue. This paper presents a Web service capability description framework based on the environment ontology. This framework depicts Web services capability in two aspects: the operable environment and the environment changes resulting from behaviors of the Web service. On the basis of the framework, a requirement-driven Web service composition model has been constructed. This paper brings forward the formalization of Web service interactions with psi calculus. And an automatic mechanism converting conceptual capability description to the formal process expression has been built. This kind offormal specification assists in verifying whether the composite Web service model matches the requirement.
