The authors employ element index, attribute index and structure index to record the XML document structure so as to excel the XML expressing capability.

指出传统信息检索技术对XML文档的处理,没有考虑其结构信息,描述粒度不够细致,故不能充分挖掘XML文档的表达能力;认为采用元素索引、属性索引和结构索引来记录XML文档的结构信息,可在细粒度上记载XML文档的结构,从而深层次地挖掘XML文档的表达能力。

In order to establish efficient access path, the authors put forward a structure index for XML data, and introduce a method of implementing operations based on.

为了建立高效地访问路径提出了一种 XML数据的结构索引 ,并介绍了利用结构索引实现基本的数据操作的方法 。

This paper introduces the research situations on MarcXchange document and discusses deeply the structure index techniques based on MarcXchange document,which includes the logical structure,schema analysis,structure index framework,index algorithm,updates for structure index.

介绍了目前MarcXchange文档的研究现状,对基于MarcXchange文档的结构索引技术(其中包括MarcX-change的逻辑结构、Schema分析、结构索引框架描述、结构索引实现算法、结构索引更新和维护等)作了较深入的探讨,并对基于这种结构索引的查询进行了仿真实验,结果说明查询响应时间较快。
