Question

Can a pre-built entities be trained? For example, can we train pre-built personName entity to recognize or not recognize an person name?

Answer 1

@Venkata Praveen Kumar Bejji No, prebuilt entities cannot be retrained. Please refer documentation for details.

The behavior of prebuilt entities is pre-trained and cannot be modified.

You can, however, train your app by adding utterances and tagging the entity as the required entity that needs to be recognized instead of LUIS pre-built entity. This is basically neutralizing the default behavior or changing the behavior of the prebuild domain intent.
