    Antes de Iniciar

    • Make sure that the NLU Workbench plugin, NLU Workbench - Core plugin, NLU Common Model plugin, and Predictive Intelligence plugin are all installed and activated on your instance.
    • Create or use an existing NLU model for Virtual Agent or AI Search.
    • Role required: nlu_editor, nlu_admin, or admin. The editor must be assigned to the model.

    Por Que e Quando Desempenhar Esta Tarefa

    Regular vocabulary items provide the model with a synonym for words or phrases your users might use in an utterance. The model uses the synonym to replace the vocabulary when predicting the intent. Use a single word for the synonym when possible.

    Regular vocabulary items are case-insensitive by default. If you need to create a case-sensitive vocabulary item, use a pattern vocabulary item. For more information, see Create a pattern vocabulary item.
    Nota:
    Choose a synonym that is a commonly-occurring word in the same language as your model.

    In this example scenario, you are adding a vocabulary item for the word credentials. Say that your users may use credentials to refer to their password. By creating a vocabulary item, you can make sure that the system correctly predicts the intent for an utterance such as reset my credentials.
