An Efficient Web Service Annotation Method Utilizing Concept Mapping and Interface Expansion

With the number of services published on the Internet growing at an explosive speed, it is difficult for service requesters to discover satisfactory web services. The reason for this phenomenon is that traditional service organization mode lacks semantic information metadata, which results in low discovery effect. In this paper, we firstly give a service description model and then present an overall framework for service semantic annotation. Based on constructed domain ontology, mapping function of interface concept set and service interface expansion algorithm are proposed respectively. Finally, web services annotation algorithm is presented. Extensible experiment results demonstrate that annotated web services by our proposed method can more satisfy requirements of service requesters than keyword-based described web services. It can achieve higher service discovery effectiveness.
