QUESTION ANSWERING SYSTEM WITH NATURAL LANGUAGE INTERFACE TO DATABASE (original) (raw)

Question Answering (QA) is an area of natural language processing research aimed at providing human users with a convenient and natural interface for accessing information. Nowadays, the need to develop accurate systems gains more importance due to available structured knowledge-bases and the continuous demand to access information rapidly and efficiently. The need to store data in an organized manner so that searching, retrieving and maintaining of data becomes easier. To efficiently operate these database, knowledge of Structures Query Language (SQL)becomes essential. But the usage of SQL restricts the access to databases from the users who don't have the knowledge of them. A need for interface comes into the picture to enable the access of these databases even to a non-expert users. This paper describes the design to develop Telugu language Question Answering system to database. This paper describes about question answering system using Natural Language Interface to a database. Here we use the rule based algorithm for train the systems question classifier to achieve a high accuracy ratio. Keywords —Natural Language Processing (NLP), Natural Language Interface To Database (NLIDB), Question Answering System(QAS), Structured Query Language(SQL).
