Abstract: A system and method include identification of a plurality of stored multi-dimensional numerical vectors similar to a first multi-dimensional numerical vector representing the received text, identification of a first plurality of documents associated with respective ones of the identified plurality of stored multi-dimensional numerical vectors, determination of a second plurality of the first plurality of documents which are associated with a respective metadata value of the first metadata field, and prompting of a text generation model to determine relevancies of each metadata value to the received text based on the second plurality of documents.
