中文摘要：

网格环境下,服务功能匹配效果决定着网格服务质量,在分析了网格服务匹配方法中基于推理的匹配算法和相似度匹配方法中基于距离的匹配算法后,对这两种算法的精确度、复杂度和匹配效率进行了分析和比较。结合这两种算法,提出了服务功能匹配改进算法,该算法通过采用细化匹配粒度,引入深度因素等方法,增加了匹配精确度。通过实验模拟,查准率和查全率上表明该改进算法具有一定优越性。

英文摘要：

The effect of grid service matching based on function decides the quality of grid service.After analyzing the matching arithmetic base on ratiocinate and distance which base on conform,the two kinds of arithmetic from definition、complexity and efficiency of matching are analyzed and compared.Combing about the two kinds of arithmetic,a better arithmetic about grid service matching based on function is brought forward.The arithmetic changes the granularity about matching,imports the complication of depth,adds the definition of matching.By the experiment,the arithmetic has advantage on exactness and completeness.
