【摘要】 针对具有相同语义的XML数据经常具有不同表达形式的问题,采用了基于本体的语义集成方法来集成异构XML数据源,即通过一系列映射规则将XPath的局部路径与本体关联起来,将用户的RDQL查询重写为基于XML的XQuery查询,从而达到语义集成的效果。本方法的意义在于用户可以通过本体查询异构的XML数据源。更多还原

【Abstract】 Some XML data that have the same meaning usually has different presenting style,so can integrate the distributed XML data sources by ontology-based semantic integrated way.It connects XPath and ontology through a series of mapping rules,rewrites users’ RDQL query into XQuery.The value of this method is that users can find the data they need through ontology.更多还原
