微机机读汉语主题词表的设计

DESIGN OF MICROCOMPUTER BASED CHINESE THESAURUS

本文提出了一个机读汉语主题词表设计方案 ,词库以简单的结构完整地表达了主题词的各种参照关系 ,能够支持文献检索系统实现下分词扩检 ,并在 IBM2 86兼容机上作了模拟试验。同时还提出了一种符号表编码构造方法 ,可使编码占用的空间节省一半 ,且编码有较好的直观性。

This paper presents a design of machine-readable Chinese thesaurus,the database of which fully expresses in a simple structure the all-dimensional cross-reference relations among the subject terms,making it possible for the document retrieval systems to do extension searching using narrower terms.This design is proven feasible in a simulated test on IBM 286 compatible computer.It also proposes a way to code the symbal lists,where by the whole codes are more directly perceivable with 50% of the storage space saved.tion, risk investment.
