| 摘 要： | 为了满足基于Web的XML数据信息的近似搜索、数据挖掘、信息分类以及数据交换的需求,分析了XML文档相似性度量方法一集合度量方法、线性度量方法和代价度量方法。提出基于权重代价的机器学习的XML文档相似性度量算法。实验表明该算法扩展了XML文档查询范围,提高了文档的查全率和查准率。

| Abstract: | For sake of increasing requirement about approximate search,data cluster and data exchange from XML documents in the Web,the methods to measure similarity between XML documents,such as set measure,linear measure and cost measure,are given.An algorithm of measuring similarity between XML documents based on machine learning with Weight costs is presented.It extends scope for searching XML documents,and improves recall and precision for searching XML documents by experiments. |
