摘要
Web服务以其低耦合,低成本等优点,原来越受到了学术界的青睐。针对于服务组合中如何选择满足用户需求的组合方案,提出了一种基于局部服务排序的算法(I-option),它按照组合效用值递减的方向来搜索满足限制的组合,使得最终选择的组合的效用值得到了明显的提高,且实现了单方向上的搜索,简化了搜索的复杂性。
Web service has gained more and more attention because of its low coupIing and low cost.In order to choose a web service composition meeting the needs of users,this paper propose an aIgorithm which on the basis of local service ranking and searches for the composition satisfying some given constraints in a specified direction with decreasing utiIity values.This aIgorithm not onIy greatIy improves the utility values,but also realizes the singIe direction search so as to simpIify the compIexity of the probIem.
