Query in linguaggio naturale per il dominio della dieta mediterranea(Natural Language Queries for the Mediterranean Diet Domain)

This paper presents an ongoing work for allowing users to ask questions in natural language to a database management system on the domain of recipes. The system translates questions from Italian language to SQL exploiting an interlingua represented by a logical formalism such as relational calculus. There are two specific features of this project: first, the use of relational calculus as semantic representation for interlingua translation; second, the role played by pragmatic information, that is the Mediterranean diet domain implicitly encoded in the database schema.
