Abstract

With the development of Web service applications, how to realize on-demand services selection according to user's personal requirements is a hot research work in modern times. This paper proposes a Web service aggregation and organization framework. First it aggregates Web services to form service groups according to service ontology which is generated by domain modeling. Then it organizes these service groups from the aspects of Role, Goal and Process which are related to specific domain problem. Based on the semantic relationships between goals, it makes use of the semantic reasoning relationships between ontology concepts to do the matching calculation, and therefore realizes domain services aggregation. The experiment results show the service aggregation time is shortened without affecting service aggregation accuracy. In addition, the method can enhance service discovery efficiency.
