Abstract
With the wide spread of Web services in various fields, there is a growing interest in building a composite Web service, however, it is very difficult for ordinary users to specify how to compose services. Therefore, a convenient interface for generating and invoking composite Web services are required. This paper proposes a natural language interface to invoke services. The proposed interface provides a way to describe users' requests for composite Web Services in a natural language. A user with no technical knowledge about Web services can describe requests for composite Web services through the proposed interface. The proposed method extracts a complex workflow and finds appropriate Web services from the requests. Experimental results show that the proposed method extracts a sophisticated workflow from complex sentences with many phrases and control constructs.
