Abstract

Abstract: Full text retrieval based on XML is the foundation of many related research problems,such as WEB information retrieval and information extraction.Furthermore,an efficiently XML index structure is very important to accelerate retrieval.An index structure based on the node labeling schema[1] is constructed and implemented in this paper,the index structure could effectively support full text retrieval queries.At last,the comprehensive experiments are conducted,the experiment results show the index structure is better on consumed time and storage.

Key words: XML, full text retrieval, index

摘要： 在XML文档上进行全文本检索已经成为很多研究课题的基础问题,例如Web信息检索,信息抽取等。有效的XML索引结构对于加速检索速度是至关重要的,在文献[1]的基础上全面地构建和实现了一个可以有效的支持XML全文本检索的索引结构。实验表明提出的索引结构在索引构建时间、空间等性能指标上均有很好的表现。
