【摘要】 为了提高在多种来源之间发现特定服务的效率,结合信息检索技术提出了针对多源Web服务的服务发现方法,有效地克服了不同Web服务发布方式之间服务发现的障碍,综合管理多种Web服务描述及其语义信息,提供了基于语义的服务查询。在分析相关研究不足基础上给出了服务发现框架MWSD(multi-source Web service discovery),并介绍了框架中各模块的作用,说明了不同服务描述之间的映射关系。结果表明:MWSD能够自动获取不同来源,不同描述的Web服务信息,并利用不同描述之间的映射关系建立统一的Web服务资源库,管理Web服务的复杂语义,可用于互联网上开放的Web服务发现。更多还原

【Abstract】 In an attempt to enhance the efficiency of searching Web services across multiple sources,a discovery approach based on information retrieval technology was proposed,which was designed for multi-source web service.It could not only overcome the barrier among different publication strategies,but also support integrated management of diverse service description and the semantic information.The limitations of related work were analyzed and an original service discovery framework MWSD(Multi-source Web Service Discovery) was proposed.The function of each module was introduced in detail.Those mappings between different types of service description were illustrated.Results show that MWSD is capable of crawling multiple sources and establishing unified Web services′ repository.It can support the complex semantic management of Web services and be applied to the discovery of the public Web services on the Internet.更多还原
