Generating question templates in a knowledge-graph based question and answer system

A system, comprising:

• a processor;
• and
• a memory containing a program that, when executed on the processor, performs an operation, the operation comprising:
• parsing a graph database query relating to an artificial intelligence question and answer (QA) system using a predefined schema, the parsing comprising:
• extracting a first plurality of values from the graph database query relating to a where clause in the graph database query;
• extracting a second plurality of values from the graph database query relating to a return clause in the graph database query;
• and
• identifying a QA template rule relating to the graph database query, based on a match clause in the graph database query;
• and
• generating a natural language question template based on the first plurality of values, the second plurality of values, and the identified QA template rule, wherein the natural language question template is suitable for use by the QA system as part of generating a response to a natural language question.

A non-transitory computer program product comprising:

• a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code executable by one or more computer processors to perform an operation, the operation comprising:
• parsing a graph database query relating to an artificial intelligence question and answer (QA) system using a predefined schema, the parsing comprising:
• extracting a first plurality of values from the graph database query relating to a where clause in the graph database query;
• extracting a second plurality of values from the graph database query relating to a return clause in the graph database query;
• and
• identifying a QA template rule relating to the graph database query, based on a match clause in the graph database query;
• and
• generating a natural language question template based on the first plurality of values, the second plurality of values, and the identified QA template rule, wherein the natural language question template is suitable for use by the QA system as part of generating a response to a natural language question.
