摘　　要： 关键词检索方式是一种以词汇控制为主流控制方式的主题检索方式,它的致命不足是“字面匹配;”概念控制仍属于词汇控制的范畴,只是用概念的相交、概念的组配等概念逻辑方法实现的语义匹配取代传统的字面匹配。进行概念控制的核心是构建支持概念控制的知识体系。 Key words index searching is a subject index search, which means a vocabulary control means as its mainstream control, whose fatal weakness is ＇literal matching＇ ; conception control still belongs to the range of vocabulary control, but it makes use of semantic matching, which is realized by means of conception logic methods, for instance, conception intersecting, conception group matching and the like, instead of traditional literal matching. The core of conception control is to construct a knowledge system, which supports conception control.
