摘要
利用OWL-S语言描述Web服务,在组合操作中加入语义信息,实现了Web服务组合的自动化。为了提高Web服务的搜索速度,采用Chord路由算法。构建了一个P2P环境下基于Chord网络的Web服务组合模型,在其上实现了基于语义的Web服务组合,最后通过实例给出了语义Web服务自动组合过程。
Web services composition automation is implemented by introducing semantic infonnation into composition operation and using OWL-S language to describe Web services. The Chord routing algorithm is adopted to accelerate search speed of Web services. A Web services composition model is built based on the Chord network in P2P environment,on which of the semantics based Web services composition is implemented, and automatic semantic Web services composition process is demonstrated in an instance.
