WSGM-SD:An Approach to RESTful Service Discovery Based on Weighted Service Goal Model

Faced with the rapidly increasing Web services, it becomes a challenging issue for users to effectively and accurately discover and reuse services. Existing service discovery approaches are mainly developed for services with WSDL documents, while only a few attention is being paid to services described in natural language, especially to the RESTful services. Towards this issue, we introduce aWeighted service goal model (WSGM) by measuring the weights of service goals extracted from the textual descriptions of services. Based on the WSGM, a novel service discovery approach called Service discovery based onWSGM (WSGM-SD) is proposed. Experiments on ProgrammableWeb, a public Web service repository, demonstrate the effectiveness of the proposed approach.
