摘要RChiQL是一个基于受限汉语的关系数据库查询语言界面的计算模型,其中文法分析占有重要地位。本文引入了一种新的文法GWERSC(Grammar with ER Semantic Characteristics , ER语义特征文法) ,设计了分析算法,其内嵌的ER语义特征有利于排除语法分析的歧义并可简化语义分析。
Abstract:RChiQL is a computational model of rest rictive-Chinese-based query interface to relational database in which grammar parsing takes very important place. A new grammar named as GWERSC(Grammar with ER Semantic Characteristics) is put forward and it's parsing algorithm is designed and implemented in which the embedded Semantic Characteristics can contribute to syntactic parsing and simplify semantic processing.
