Studies on Er-model-based Restrictive-Chinese Query Language of Database
Cui Zong · Zhongwen xinxi xuebao · 2001
A computational model of ER model based restrictive Chinese query language of relational database is put forward which simulates the langguage process mechanism of human and the process of communicating in natural language is divided into four mutually dependant and interlaced steps: word segmentation,parsing,semantic processing and SQL transformation.A new grammar,GWERSC(Grammar with ER Semantic Characteristics)is introduced,which could contribute to syntactic parsing and simplify semantic understanding with the help of its embedded ER model.
