摘要: Web服务发现是Web服务系统架构的重要组成部分,传统的服务发现只是简单的基于关键词的语法匹配,查询得到的服务往往不是用户想要的。分析了国内外Web服务描述与服务发现现状,提出了一种具有层次性和结构性的Web服务描述与发现算法。实验证明该算法与现有算法相比具有较好的查准率和查全率。

Abstract: Web services discovery is an important part of Web services architecture.Traditional Web services discovery is just a kind of simple syntax match based on keywords.The services resulted from such queries can’t meet users’ satisfaction.This paper analyzes situation of Web services description and discovery at home and abroad and raises an algorithm of Web services description and discovery with hierarchical and structural.The experiments show that this arithmetic has higher precision and recall than others.
