Mapping entities in conversation text
To prevent your Pega Intelligent Virtual Assistant™ (IVA) from asking for information that the user has already provided, you can optionally configure entity mapping definitions for the cases configured in your channel. When the IVA creates a case during a chat session, the system applies the associated entity mapping and copies any entities extracted from the user input into the case properties.
For example, for a Car Insurance case, you can map the CarModel and CarMake entities to the .CarModel and .CarMake case properties. When these entities are detected in a chat conversation, their values are automatically assigned to the case properties and the system does not ask the user about the car make and model.
When a case property has a value stored in it that was mapped from a detected
entity, the IVA will skip over this question shape. This prevents the chatbot from
asking for information that the user has already provided.
