基于结构化信息检索系统的数据搜集技术的研究

Research on Data Collection Base on Structured Information Retrieval

本文在已有的传统信息检索系统中数据搜集技术研究基础上,采用了正向最大匹配和逆向最大匹配法的分词技术和基于向量距离的分类技术,建立了可以将XML文档映射到关系数据库的信息检索系统,从而大大提高了信息检索的效率。

In this paper,on the base of conventional information retrieval's data collection technology study,adopted most converse matched method and most positive director matched method's segmentation technology and base on vector space technology,build a information retrieval system which can make XML document map RDMS.So the system can enhance the effecting of the retrieval system.
