QoS感知语义Web服务组合中搜索空间缩减方法
A Methodology for Search Space Reduction in QoS Aware Semantic Web Service Composition
摘要:
语义信息规范了Web服务的表达能力。国家的最先进的方法在Web服务的研究已经使用的语义Web服务用于不同的目的,主要是服务发现,组合,执行等。在本文中,我们的主要重点是语义驱动的服务质量(QoS)感知服务组合。目前的服务组合方法大多使用语义信息来组合服务以生成组合解决方案。然而,在本文中,我们的意图是使用语义信息,以加快服务组合算法。在这里,我们提出了一个服务组合框架,使用语义信息的Web服务生成不同的集群,其中的服务是语义相关的集群内。我们的最终目标是构建一个组合解决方案,使用这些集群,可以有效地扩展到大的服务空间,同时确保解决方案的质量。实验结果表明了该方法的有效性。
英文摘要:
The semantic information regulates the expressiveness of a web service. State-of-the-art approaches in web services research have used the semantics of a web service for different purposes, mainly for service discovery, composition, execution etc. In this paper, our main focus is on semantic driven Quality of Service (QoS) aware service composition. Most of the contemporary approaches on service composition have used the semantic information to combine the services appropriately to generate the composition solution. However, in this paper, our intention is to use the semantic information to expedite the service composition algorithm. Here, we present a service composition framework that uses semantic information of a web service to generate different clusters, where the services are semantically related within a cluster. Our final aim is to construct a composition solution using these clusters that can efficiently scale to large service spaces, while ensuring solution quality. Experimental results show the efficiency of our proposed method.
