In this paper, we have studied a common Web service composition problem, the syntactic matching problem, where the output parameters of a Web service can be used as the input parameters of another Web service. Many automatic Web service composition algorithms based on AI planning techniques have been proposed. However, most of them do not scale well when the number of Web services increases, or may...
Many automatic Web service composition algorithms based on AI planning techniques have been proposed. In this paper, we model the semantic Web service composition problem using a kind of simplified planning graph. It provides a unique search space, and can find a solution in polynomial time, but with possible redundant Web services.
