Generation of Natural Language Queries from ER-Diagram

Authors(2) :-Srinivasa K, Kavitha M

The concept of object-oriented modelling makes the real world represented in some kinds of logical forms.ER-diagram is one of those logical forms, which is used in database design. Many tools are available to generate ER-diagram from natural language database requirement specifications and SQL queries from natural language queries (NLQs). Here we address the problem of generating natural language queries from ER diagram so that user efforts in typing NLQs can be reduced. The proposed method first converts the given ER-diagram to understandable format that is intermediate text or sentence form and then the NLQs are generated from the intermediate form using Natural Language Processing (NLP) techniques.
