Corpus Based Context Free Grammar Design for Natural Language Interface to Database
For practical implementation of Natural Language Interface to Database, deep semantic analysis needs to be used as it increases success rate and portability. Deep analysis uses more language knowledge rather than the domain knowledge. A primary step in deep semantic analysis is formalizing syntax of possible input questions. This paper describes a context free grammar designed for a domain specific natural language interface to database. The grammar is designed for the domain Railway Inquiry for which corpus of question is collected and analyzed.
Keywords: Natural Language Interface to Database, Corpus of Questions, Context Free Grammar, Deep Semantic Analysis
