Abstract: Goal Web services description languages and service discovery algorithms are methods of dealing with the Web services discovery problem. Based on the analysis of the current Web services description languages, the paper designs a goal Web service description ontology which can depict the functional features, the performance features and the semantic features of Web services. With the principle of enhancing efficiency and quality of the service discovery, it presents a Web services feature elements-based service discovery model, and implements a prototype system in the tourist domain.

Key words: Web services, service ontology, service discovery
