摘要:

随着互联网上Web服务数量的增多,如何快速准确地发现满足用户需求的Web服务已经成为一个亟待解决的问题。现在很多基于语义的Web服务发现方法都是基于IO匹配,当语义匹配失败时再采取其他措施来弥补。然而只是单纯的基于IO匹配语义Web服务发现的准确率并不高,提出了基于约束提取与结构分析的语义Web服务发现算法。算法分为两部分,首先进行基于约束提取的概念语义匹配,当匹配失败时再采取基于结构分析的算法。使用OWLSTC 2.0作为测试集合对该方法进行测试。结果表明,所提出的方法有效地提高了服务发现准确率。

Abstract:

With the increase of the number of Web services on the Internet, how to find a web service that can meet users’ requirements quickly and accurately has become a problem to be solved. Currently, many semantic web service methods are based on IO matching .They use other ways if semantic matching is failed. However, the accuracy of semantic web service discovery based on IO matching purely is not high enough. Semantic web service discovery algorithm is proposed, which is based on constraint extraction and structure analysis. It consists of two parts. Firstly, the conceptual semantic matching based on constraint extraction is carried out. Secondly, it uses the algorithm based on structure analysis while matching is failed. owlstc2.0 is used as test set to validate this method . Experimental results show that this method can improve the accuracy of service discovery effectively.
