树匹配与XML信息检索研究

The Research of Tree Matching and XML Retrieval

随着可用XML文件数量不断增多,很多检索方法被提出用于XML文献检索。它们通常使用树型结构表示文件和进行查询。主要研究树匹配查询理论方法及这些方法是如何被引入XML文件查询与检索中,通过这些研究也提高了我们的XML研究理论知识。

With the increasing number of available XML documents,numerous approaches for retrieval been proposed in the literature.They usually use the tree representation of documents and queries to process them.In this paper,we aim at studying the theoretical approaches proposed in the literature for tree matching and at seeing how these approaches have been adapted to XML querying and retrieval.This study will allow us to highlight theoretical aspects.
