Cause

This is most likely happening due to lack of data for products or individual customers. You can check if this is the case by trying to train a model just for language and sentiment since language and sentiment doesn't require a certain data volume. If this processes successfully this means the issue is most likely not to do with a technical issue but is is due to the lack of volume of data for products or individual customers in the system.

The Ticket Natural Language Processing Classification scenario includes the following entities:

  • Ticket language - no data needed.
  • Sentiment - no data needed.
  • Product ID - Requires a sufficient amount of products in the system.
  • Serial ID - Requires a sufficient amount of products in the system.
  • Sales Order ID - Requires a sufficient amount of Sales orders in the system.
  • Customer ID - Requires a sufficient amount of individual customers in the system.

Resolution

To train the functionalities other than Ticket Language and Sentiment please ensure you have sufficient data volume and good data quality for the model to use in its training.
