Train and publish NLU model

1E ITSM Connect uses ServiceNow's Natural Language Understanding(NLU) to comprehend word meanings, recognize word contexts, and infer user or system actions. 1E ITSM connects specifically uses this NLU engine to perform recommended actions feature. The ITSM Connect application has its own NLU model and can be customized based on the requirement. In the customer environment, this model is trained and published automatically using fixed scripts. However, to manually configure it, follow the below given steps.

  2. Navigate to NLU Workbench → Models in the application navigator. The page NLU Workbench opens up with the list of All existing models on the right side of the window panel. Look for 1E Recommended Actions NLU model in the list as shown in the picture below.
