一个基于P2P和本体分类的Web服务发现模型

An Ontology-Based Classification and P2P-Based Web Services Discovery Model

服务发现是Web服务应用中极其重要的环节。随着Web服务数目的增长和对实时性需求的增加,集中式的服务发现机制难以满足实际需求,分布式服务发现机制成为Web服务应用的一个新研究方向。本文基于P2P的底部架构,实现了一个根据本体对服务注册节点进行语义分类的Web服务发现模型,并对其发现效率和节点的负载进行了评估。

Service discovery plays a very important role in Web service applications. Current Web service discovery mechanism requires replication of all Web service publications in all registries. Large growth in number of Web services as well as the growth in the number of registries makes this replication impractical. Distributed Web services discovery mechanism is put forward. We come out with a service discovery model which is based on semantic classification of registries and P2P infrastructure. The design and an experimental evaluation of the model are presented.
