D-HIRD: Domain-independent Hindi language Interface to Relational Database

Person with no knowledge of database language may find it difficult to access the database. Many systems were developed to access the information from the database using natural language. But these systems are domain-dependent i.e. they were developed for a particular domain. We develop a system called D-HIRD for Hindi language which provides domain-independence. For developing a domain-independent system, we divide our system into two modules: Language processing module and Database module. Language processing module use Hindi Shallow Parser for analyzing and parsing the input query. We introduce a domain-identifier component in database module which identifies the domain by using knowledge base. We use three database domain and 80 queries for each database for testing our system. The system is able to correctly identify the domain from the query and translate it into SQL which is executed on the database and result is provided to the user in Hindi language.
