摘　　要：XML因其灵活性和易扩展性已经成为Web上异构数据转换和传输的标准,但是含有不同模式的XML数据源之间却很难进行相互操作,这给XML数据检索带来了很大的不便.提出一种从XML模式到OWL本体的转换算法,然后借助共享全局本体和同义词典实现转换后的本体在语义上的相互映射,从而解决XML结构异构的问题,最后提出了利用本体串连实现XML语义查询的方法.与传统方法比较,实验结果验证了该方法的有效性.XML is becoming the standard of exchange and translation between heterogeneous data on the Web,but different XML data sources belong to different XML models can hardly complete interoperability,which makes inconvenience for XML searches.An algorithm is provided to transform XML models into OWL ontology in this paper,then a way for realizing mapping among these ontologies is given by a shared global ontology and a thesaurus to resolve this heterogeneous structure problem.Based on this ontology aligning method a system of XML semantic query is achieved at last.Comparing with traditional methods,experiments prove that this method is valid.
