摘　　要：中文数据库自然语言查询的研究有两个基本目标 ,首先解决 NL IDB面临的可移植性和可用性的问题 ;其次提出适合中文自然语言查询处理的特有方法 .为此开发了中文数据库自然语言查询系统 NChiql.从总体设计的角度 ,介绍了 NChiql中的可移植性体系结构、中文自然语言查询分析、基于数据库语义的自然语言查询分析与转换和智能界面管理等内容 .实验表明 ,该系统具有良好的可用性及高效和鲁棒的语言分析器 .There are two goals in the research on the Chinese natural language queries: First, to solve the portable and usable problem in NLIDBs; and second, to present a novel mechanism adapting to Chinese natural language queries. Described in this paper are the design and implementation of NChiql, a Chinese natural language interface to databases. Also discussed are the natural language query structure analysis and its processing in NChiql. The main contribution of NChiql is depicting a novel method based on database semantics to handle the Chinese natural language query. The experiments show that NChiql has good usability and high correctness.
