Abstract

With the rapid growth of Web services, services must be stored in repositories. To enhance the discovery efficiency of Web services, it is necessary to preprocess the services in the repository to achieve an effective organization structure. A RGPS-based service preprocessing method is proposed in this study. Services are firstly clustered based on the domain ontology and the RGPS model. The particle swarm optimization algorithm is then used in the service composition according to the frequent service request. This method leads to a rapid matching between services and the RGPS requirement model and acceleration in the service discovery.
