Change of Related Data

[Daniel061]

Is your feature request related to a problem? Please describe.
The user can say "The dog is black." and the program will associate the adjective 'black' with dog for future information.
The user can then say "The dog is white." and the program will blindly store the additional adjective with the noun dog regardless of the change of description.

Describe the solution you'd like
The program should remind the user that he previously said the dog was black but is now saying the dog is white. The program should question the user about this change. If the user insists, the adjective associated with the noun dog should be replaced or stored in an order of preference.
(NOTE) The program will need to check if black and white are related as in associated with the same noun like color before questioning this change. This can get complicated.

Describe alternatives you've considered
Thinking about how I'd react to new information, I'd definitely remember the first information but use the second in referencing the dog.

Additional context
Suggestions on proper handling on this situation are welcomed.
