    Por Que e Quando Desempenhar Esta Tarefa

    Many ServiceNow products, such as ITSM, HRSD, and CSM include NLU models for Virtual Agent (VA) topics. The NLU plugin contains entities that are common across all products. You can modify those models. To learn how to train and test the models used for VA conversations, see Natural Language Understanding.
