摘　　要：Web Services 是基于 Internet 进行分布式计算的基本元素,面向 Service 的计算将成为未来计算技术发展的趋势。但如何能够自动发现需要的 Service 资源,提高 Web Services 组合的智能化程度,是近来的研究热点之一。IRS-Ⅱ首先提出基于任务本体的 Service 发布、发现和组合方法,可以说是将 Service 发现和组合从语法的层次提升到了语义的层次。本文首先深入分析了IRS-Ⅱ提出的方法及其体系结构,然后对 Web Services 的智能检索和服务组合的问题进行讨论。Web Services are essential in internet based distributed computing, Service-oriented computing will become the direction of computing technology. The problems of how to discover proper Services automatically and how to enhance the intelligent composition of Web Services are within the hot topics recently. IRS-Ⅱ is a framework for Web Services composition. It proposes a task ontology-based methodology of Service publishing, discovery and composition, which enhances the level of Service discovery and composition from syntax to semantics. This paper firstly investigates the methodology and architecture of IRS-Ⅱ in depth. And then some deeper topics in the intelligentized Web Services discovery and composition have been discussed.
