自然语言检索中的概念语义控制

Concept Semantic Control in Natural Language Retrieval

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、概念的匹配等逻辑方法实现的语义匹配取代传统的字面匹配。如何将检索从关键词层面提高到知识(或概念)层面,是目前情报信息检索领域研究的一个热点。文章通过对概念检索、语义检索以及两者之间关系的阐述,说明了如何实现自然语言检索中的概念语义控制,从而能够从概念语义层面上来认识和处理用户的检索需求。

Keywords retrieval is a subject retrieval method of using vocabulary control as its mainstream control,and its fatal weakness is ＂literal matching＂.Concept control still belongs to the category of vocabulary control,but it replaces traditional literal matching with the semantic matching realized by the logic methods such as concept intersecting and concept matching.How to improve retrieval from Keywords to concept level is a research hotspot in information retrieval field.By expounding concept retrieval,semantic retrieval and the relationship of them,we explain how to realize the concept semantic control in natural language retrieval for knowing and processing the retrieval requests of users on concept semantic level.
