中文自然语言数据库查询系统

A Database Inquiry System for Natural Chinese Language

本系统是一个建立在关系数据库上的中文自然语言接口系统。借鉴了国内外自然语言数据库接口设计的理论和方法。对汉语处理方法不同于传统方法,所用的语法信息不是传统意义下的词与词的搭配结构,而是属性项的搭配结构,语义信息不是广泛意义下的句子信息,而是面向数据库查询系统的操作语言信息。查询句的分析重点放在对操作语义项的提取,本系统用C语言编写,是一个面向实用的汉语接口系统。

This system in fact a Chinese language interface system set up on the rela-tional database, by virtue of the background of domestic/foreign experiencesin interface design for natural language database. However, the naturalChinese language processing differs from others since its syntax structure iscollocatod among Attribute Items instead of the conventional collocation amongwords. In particular, it is running with operational semantic informationfacing database inquiry system instead of the sentence information as usuallyunderstood. To analyze a sentence inquired for, what should be done is mainlyto extract the operational semantic items. As programmed in C language, it isan application-oriented Chinese interface system.
