基于加权XML模型的XML数据与DTD模式匹配

The Schema Matching of XML and DTD Based on Weighted XML Data Model

首先说明利用加权XML数据模型分别得到标准XML参考实例和XML数据实例的方法,并对DTD约束修饰符的表达方法进行介绍。其次,详细阐述相似度算法的实现方法,重点说明在XML数据实例中寻找与标准XML参考实例的匹配节点算法和计算标准XML参考实例与XML数据实例的相似度算法。最后,对相关实验及其结论进行总结。

This paper first introduces standard XML reference instants and XML data instants based on the weighted XML data model. Then it displays the expression ways of constraints in DTD. Furthermore, the paper also shows the approaches on how to implement similarity algorithm, with an emphasis on how to find out a matching node with standard XML reference instants and to get the similarity algorithm of standard XML reference instants and that of XML data instants.
