Translating a natural language query into a formal data query

A computer system for performing a computer-implemented method for generating ground-truth for natural language querying, the system comprising a processing unit, a storage system and a user interface comprising an input unit and a display, the system being configured to:

• store a knowledge graph as data model in the storage system;
• receive, via the user interface, a natural language query;
• translate the natural language query into a formal data query;
• visualize the formal data query on the display;
• receive, via the input unit, a feedback response from a user, the feedback response comprising a verified and/or edited formal data query;
• and
• store the natural language query and the corresponding feedback response as ground-truth pair in the storage system.

A computer program product for performing a computer-implemented method for generating ground-truth for natural language querying on a computing system, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by the system to cause the system to perform a method comprising:

• providing a knowledge graph as data model;
• receiving a natural language query from a user;
• translating the natural language query into a formal data query;
• visualizing the formal data query to the user;
• receiving a feedback response from the user, the feedback response comprising a verified and/or edited formal data query;
• and
• providing the natural language query and the corresponding feedback response as ground-truth pair.

A user interface comprising a display and an input unit, the user interface being configured to:

• receive a natural language query from a user;
• provide the natural language query to a translation module;
• receive a formal data query from the translation module, the formal data query being a translation of the natural language query in a formal language;
• visualize the formal data query on the display;
• receive a feedback response from the user, the feedback response comprising a verified and/or edited formal data query;
• and
• provide the natural language query and the corresponding feedback response as ground-truth pair.
