摘要：
Two Natural Language Interface to Database (NLIDB) systems have been developed. One is using a Template Grammar based approach and another is using Keyword based approach. Both the systems accept queries in Bengali language. In both the approaches, the user query is analyzed and translated to a SQL statement that is used to retrieve information from the database. The systems have been evaluated based on precision and recall metrics. The NLIDB system based on Keyword based approach has been observed to perform better. The Keyword based approach has been extended further to develop a dialogue based question answering system for Railway information in Telugu language.
