摘　　要：随着计算机应用的普及和网络技术的飞速发展,位于网络上的Web服务的数量和种类也与日俱增,如何快速准确地发现满足用户需求的Web服务变得越来越重要。针对现有的Web服务体系结构存在不可扩展、语义信息不足和服务发现效率低等问题,提出了一种可扩展语义Web服务体系结构,以满足现代企业基于SOA构建分布式大规模复杂系统的需求。研究了该体系结构中服务的发布与删除算法,以及由服务的发布与删除引起的Web服务体系结构上的动态调整算法,从而使系统的存储资源得到充分利用,保证了服务的发现效率。研究了基于OWL-S描述的Web服务发现过程及算法,利用仿真实验验证了所提的方法的可行性。With the rapid development of computer and network technologies, the variety and quantity of Web Services on the network is also increasing. How to find the requiring services quickly and accurately becomes increasingly important. In order to solve the problems with traditional Web Services architecture, such as poor scalability and lacking of semantic information, a scalable semantic Web Services architecture was proposed, the architecture could meet the requirements to construct distributed and large-scale systems based on SOA for modem enterprises. Service publication and deletion algorithms of the architecture were studied, and dynamic adjustment algorithms of the architecture was studied which were led by service publication and deletion, thus making full use of the storage resource and guaranteeing the efficiency of service discovery. The service discovery process of the architecture was described, and service discovery algorithm based on OWL-S was studied. Simulation experiments were used to validate the proposed method.
