title: Automatic Web Service Composition with Abstraction and Refinement creator: Kil, Hyunyoung creator: Nam, Wonhong creator: Lee, Dongwon description: The behavioral description based Web Service Composition (WSC) problem aims at the automatic construction of a coordinator web service that controls a set of web services to reach a goal state. However, solving the WSC problem exactly with a realistic model is doubly-exponential in the number of variables in web service descriptions. In this paper, we propose a novel efficient approximation-based algorithm using automatic abstraction and reļ¬nement to dramatically reduce the number of variables needed to solve the problem. date: 2009-04 type: Conference or Workshop Item type: PeerReviewed format: application/pdf identifier: http://www2009.eprints.org/141/1/p1121.pdf identifier: Kil, Hyunyoung and Nam, Wonhong and Lee, Dongwon (2009) Automatic Web Service Composition with Abstraction and Refinement.
