基于语义的Web服务发现模型研究

Research on web service discovery model based on semantic technology

Web服务发现是Web服务系统架构的重要部分,现有的主流Web服务发现方法是采用基于UDDI框架的服务匹配,但由于UDDI注册中心只能提供基于关键字的查询,并且缺乏对语义信息的支持,造成服务的查准率查全率得不到保证。针对目前Web服务发现技术存在的不足,引入了语义技术,并设计了一个基于语义的服务发现原型,来验证提出的基于语义的服务发现方法的可行性。

The web service discovery is the important part of web service systems construction. At present the mainstream approach to web discovery adopts the service matching based on the UDDI framework. However, UDDI register center only offers the search route through key words as well as lacking in the support of semantic information, thus causing inaccuracy and incompleteness. In response to the deficiency of present web service discovery technology, a solution to the problem-semantic technology is proposed and service discovery archetype framework is designed, so as to testify the feasibility of service discovery approach based on semantics.
