一种用于计算机情报检索系统的主题词处理方法

A Method for the Description Word Processing of Computer Information Retrieval

本文提出一种建立在改进的倒排文件结构基础上的主题词处理方法,用于微型计算机情报检索系统中,它是以若干相关数据库及其互访指针形成的体系结构为核心,并辅以一系列词串预处理、查找、插入、删除法来实现主题词处理的,该方法能有效地节省存贮空间,动态生成主题词典,并有较快的主题检索速度,且提供用户的主题词操作界面友好方便,合符习惯。

This paper presents a metod based on changed inverted file structure, which is used in microcomputer information retrieval system. We process description words by a series of algorithms about character string pre-processing, search, insert and delete on several data bases connected by pointers. This method can efficiently save memory space, actively get thesaurus and have quicker theme-searching rate. In addition, it can also make one feel convenient while he is operating about description words.
