Interactive assistance for executing natural language queries to data sets

A method, comprising:

• receiving a natural language query via an graphical interface for a business intelligence service that provides access to a plurality of different data sets;
• identifying, by the business intelligence service using one or more machine learning models trained for natural language processing, a plurality of candidate entity linkages between an entity recognized in the natural language query and respective columns from one or more of the plurality of different data sets;
• responsive to a determination that respective confidence scores determined by the one or more machine learning models for the candidate entity linkages identified for the entity are not above a minimum confidence threshold:
• underlining, in the graphical interface, the entity in the natural language query to indicate that the entity is ambiguous;
• and
• providing, in the graphical interface, a prompt to resolve the ambiguity of the entity before a result of the natural language query is provided.

One or more non-transitory computer-readable storage media storing program instructions that, when executed on or across one or more computing devices, cause the one or more computing devices to implement:

• receiving a natural language query via an graphical interface for a business intelligence service that provides access to a plurality of different data sets;
• identifying, using one or more machine learning models trained for natural language processing, a plurality of candidate entity linkages between an entity recognized in the natural language query and respective columns from one or more of the plurality of different data sets;
• responsive to a determination that respective confidence scores determined by the one or more machine learning models for the candidate entity linkages identified for the entity are not above a minimum confidence threshold:
• underlining, in the graphical interface, the entity in the natural language query to indicate that the entity is ambiguous;
• and
• providing, in the graphical interface, a prompt to resolve the ambiguity of the entity before a result of the natural language query is provided.
