基于与或图的Web服务组合的研究

现在Web服务技术的应用变得更为普及。单个Web服务只提供有限的功能,难以满足实际应用的需要。Web服务组合已经成为Web服务应用中一个非常重要的研究方面。本文提出了一种基于与或图的Web服务组合方法,该方法通过对已经访问过的服务进行标记,以服务代价作为在与或图中进行搜索的依据,缩小了搜索空间,能够快速找到一种代价很小的服务组合方法。仿真实验表明,该方法提高了Web服务组合的效率和成功率。

Web Services Composition Based on AND/OR Graph

Now Web service technology become more and more widely used.Single Web service just provides limited functionality and can not meet the demand for practical applications.Web services compostion has become a very important research aspect in Web services application domain.In this paper,we proposed an approach based on and/or graph to compose Web services.This method labels the services which have been visited and searches in the and/or graph on the basis of service cost.It reduces seach space and can find a service composition approch which has a very small cost quickly.The results of the simulation experiments show that this method improves the efficiency and success rate of Web services composition.
