基于XML的信息检索技术

Information Indexing Based on XML

传统的信息检索方法无法为用户准确地提供所需的资料,这主要是由于传统的HTML网页结构上的缺陷造成的。文中通过比较HTML文档和XML文档在结构和语义上的差异,阐述了XML文档在信息检索技术中的优势和XML文档必将成为新一代网页模式的趋势。目前已经有很多权威编程工具和数据库支持从XML文档中抽取信息,越来越多的软件提供XML接口,文中以Microsoft公司的.NETFramework为例,介绍了如何从XML文档中检索信息。试验证明基于XML的信息检索技术较好地解决了Internet上资料获取的困难。

Although there are plentiful resources in the Internet,it is difficult for users to get what they really need in traditional indexing way.It is the structural and semantic limitations of traditional HTML document that has resulted in the problem.XML document owns the advantages of information indexing and the certain tendency to become new generation page designing mode in comparison with HTML document.More and more programming tools and databases including some famous ones have reportedly supported to XML document.This paper offers a method by taking Microsoft.NET Framework as an example.Experiments prove that it is a better way to get information on Internet.
