Method for improving the accuracy of a statement

A cognitive assistant (CA) system configured to improve an accuracy of a statement, the CA system comprising memory for storing instructions, and a processor configured to execute the instructions to:

• receive from a user an original statement comprising a plurality of statement entities;
• generate an original confidence estimate (CE) for a correctness of the original statement;
• generate a replacement statement by:
• selecting a suspect statement entity in the plurality of statement entities;
• selecting a replacement entity for the suspect statement entity;
• replacing the suspect statement entity with the replacement entity in the original statement to generate the replacement statement;
• generate a replacement CE for a correctness of the replacement statement;
• send the replacement statement to the user when the replacement CE exceeds the original CE by a tuning factor;
• and
• repeat generating the replacement statement and generating the replacement CE when the replacement CE does not exceed the original CE by the tuning factor.

A computer program product for improving an accuracy of a statement, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• receive from a user an original statement comprising a plurality of statement entities;
• generate an original confidence estimate (CE) for a correctness of the original statement;
• generate a replacement statement by:
• selecting a suspect statement entity in the plurality of statement entities;
• selecting a replacement entity for the suspect statement entity;
• replacing the suspect statement entity with the replacement entity in the original statement to generate the replacement statement;
• generate a replacement CE for a correctness of the replacement statement;
• send the replacement statement to the user when the replacement CE exceeds the original CE by a tuning factor;
• and
• repeat generating the replacement statement and generating the replacement CE when the replacement CE does not exceed the original CE by the tuning factor.
