QUEST: A Natural Language Interface to Relational Databases
Proceedings of the Eleventh International Conference on Language Resources and Evaluation (LREC 2018)
Abstract
Natural language interfaces to databases systems allow the user to use natural language to interrogate a database. Current systems mainly focus on simple queries but neglect nested queries, which are predominant in real cases. We present a NLIDB system, QUEST, which is able to cope with nested logic queries, without imposing any restriction on the input query. QUEST outperforms a strong baseline system by 11% accuracy.
