分类表-叙词表转换系统的设计

摘要

The key problem is to create a classification number-descriptor parallel index database during the design of a vocabulary switching system. In this paper, LogL measure is introduced to create a Chinese Library Classification-Chinese Thesaurus database on the basis of some document indexing databases. Two methods in this system can complete the switching between a classification number and descriptors.%本文针对手工建立分类表-叙词表转换系统的缺点，用计算机设计了一个分类表-叙词表转换系统。系统以文献数据库标引数据(《中图法》及《汉语主题词表》)为实验对象，以金融银行学科为例建立了四种标引词(串)与分类号的对应模型，采用LogL统计方法实现分类号与主题词的自动对应和人工辅助筛选，并设置了模糊转换和精确转换两种分类号与主题词转换的模式。
