Semantic representations for knowledge modelling of a Natural Language Interface to Databases using ontologies

Year: 2015

Type: article

Abstract: "Despite the large number of Natural Language Interfaces to Databases (NLIDB) that have been implemented, they do not guarantee to pr ovide a correct response in 100% of the queries. In this paper , we present a way of semantic modelling the elements that integrate the knowledge of a NLIDB with the aim of increasing the number of correctly - answered queries. We design semantic representati ons in order to: a ) model any relational database schema and its relationship with the natural language and b ) add metadata to natural language words to enable our NLIDB to interpret natural language queries that contain superlatives. We configured our NLI DB in a relational database that we migrated from Geobase and used the Geoquery250 corpus to evaluate its performance. We compare its performance with the interfaces ELF, Freya and NLP - Reduce. The results indicate that our proposal allowed our NLIDB to obt ain the best performance."
