Natural language generation for database queries

A method for natural-language database queries, comprising:

• receiving a natural language query for querying a database, the natural language query not being in a format compatible with a format for querying the database;
• determining a plurality of candidate database queries by applying the natural language query to a query generation language model;
• determining a plurality of candidate database query results, each corresponding to the plurality of candidate database queries, by querying the database with the respective candidate database query;
• selecting a candidate database query by providing natural language query, the plurality of candidate database queries and associated sets of candidate database query results to a query evaluation language model;
• and
• providing the selected candidate database query or the associated set of candidate database query results as a response to the natural language query.

A non-transitory computer-readable medium for natural-language database queries, the non-transitory computer-readable medium comprising instructions executable by a processor for:

• receiving a natural language query for querying a database, the natural language query not being in a format compatible with a format for querying the database;
• determining a plurality of candidate database queries by applying the natural language query to a query generation language model;
• determining a plurality of candidate database query results each corresponding to the plurality of candidate database queries, by querying the database with the respective candidate database query;
• selecting a candidate database query by providing natural language query, the plurality of candidate database queries and associated sets of candidate database query results to a query evaluation language model;
• and
• providing the selected candidate database query or the associated set of candidate database query results as a response to the natural language query.
