Abstract:
Today, there is a growing need for user to be able to express, and get answers to more complex requests, those including multiple functionalities, conditions, constraints and objectives. Complex requests including multiple functionalities only can not usually be answered with one single Web service. As multiple services are needed, the problem is then to find good combination using the available services. This paper contributes to answering this issue. It focuses on the problem of semantic Web services composition to answer such requests. We propose an automatic composition algorithm designing the answering composition. The algorithm takes into account all suitable composition structures. The set of answering composition is modeled as a graph, which supports the selection of the best composition according to the request constraints and objectives.
