| 摘 要： | 文章在集成异构分布式XML数据源时,提出一种基于本体的数据模型来描述XML数据的语义信息,以实现带有一定逻辑推理功能的智能查询。即通过一系列映射规则将XPath的局部路径与本体中的概念及角色关联起来,将用户查询重写为基于XML的XPath查询,本系统的目标是使用户可对Web上各XML数据源进行基于本体的查询。

| Abstract: | In order to achieve heterogeneous and distributed XML integration,an ontology-based data model is proposed to represent the semantic information of XML data and to realize the intelligent query with certain logical reasoning function. The local paths of Xpath are related to the concepts and roles of an ontology by a set of mapping rules,and the user queries are translated into the queries expressed in an XML-based query language,e.g. Xpath. The objective of the presented system is to help users to carry out ontology-based queries to diverse XML repositories. |
