信息集成系统中的XML Schema匹配算法研究

Study on XML Schema Matching in Information Integration System

模式匹配是信息集成过程的关键技术之一,本文提出一种基于XML Schema的模式集成,主要采用基于节点对之间的语言学和结构相似度实现XML Schema匹配,为避免两个节点本身代表不同的含义但却由于其结构相似性很高而集成在一起的情况,采用语言学相似度过滤掉语言学相似度小于指定阈值的节点,使其不再参与后续的结构匹配算法.通过案例分析表明,此方案能够达到较好的效果.

Information integration has already gained great attention , and schema matching is a key prob-lem in the information integration system .In this paper , a method based on linguistic and structural similarity for XML Schema automated matching problem was presented .This solution contributed in solving the mismatching of given source and target schema elements which have high structural similarity but less linguistic similarity .In the solution , the structural similarity do not be done if the linguistic similarity less than the threshold .Experimental results demonstrate the effectiveness of the solution .
