数据库汉语查询系统中隐含知识查询的研究

The Study of Database Implicit Knowledge Retrieval in Database of Chinese Interface

该文讨论了目前现有数据库汉语查询系统中的存在问题,根据关系数据库中数据表示与自然语言(汉语)查询句的语义模型不同,提出了数据库汉语查询时隐含知识的查询,对数据库中的隐含知识以概念图来表示,从而建立了自然语言和数据库查询命令SQL语言的直接联系。实现了这种数据库隐含知识查询的实验系统,从一定程度上提高了数据库汉语查询的智能性。

This paper discusses the problem of the Database's natural language interface at present.According to the difference between the data present of relation Database and the module of Chinese query sentence,the paper proposes the implicit-knowledge querying when the Database query sentence is Chinese sentence,this implicit knowledge is in concept-graph,and the direct relation between Chinese query sentence and SQL command is erected.The paper also implements a Natural Language interface of relation Database with the implicit-knowledge query,in some extend it en-hances the intelligence of Database Natural Language interface of relation Database.
