Web service is essential in achieving dynamic business process. With the dramatically increased number of Web services advertised in UDDI, Web Portal or Internet, how to locate the best Web service according to a user's requirement is becoming more and more important, which calls for efficient and effective Web service discovery mechanism. Considerable efforts have been attained in solving this problem...
The goal of the Web Service Composition (WSC) problem is to find an optimal "composition" of web services to satisfy a given request using their syntactic and/or semantic features, when no single service satisfies it. In this paper, in particular, we study the WSC problem from semantic aspects, exploiting the supertype-subtype relationship among parameters, and propose a novel solutionbased...
Approaches to Web service composition are dependent upon some form of repository to hold service descriptions. Most service composition software relies upon highly-optimized and proprietary formats for representing service descriptions and storing them into a repository. Unlike these approaches, this paper reports on the development and evolution of a standards-based service description repository...
In this paper, we propose a Web service composition framework that uses Integer Linear Programming with non-functional objectives and constraints, in addition to the syntactic matching of Web services features. We envision that when Web services are fully deployed and commercialized in the near future, the criteria of Web service composition to achieve objectives will vary depending on users' needs...
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.
