Correcting training data in an IVA
Improve the artificial intelligence of Pega Intelligent Virtual Assistant™ (IVA) and teach the system to more accurately respond during chat conversations by correcting the IVA training data and rebuilding the text analytics model. When the IVA correctly detects the subject matter (topic) and additional key information (entities) in a conversation, the system can then escalate the reported issue, start a related business case and ask the user for more information.
For example, after identifying the relevant topic and entities in a message, an IVA detects a request for a bank loan. The system then automatically creates a car loan business case and asks the user follow-up questions about their personal information, income, and financial history.When you enable the recording of training data and the IVA begins a conversation with a user, the system saves each chat message as a training record. You can also manually create a training record that contains information from sample conversations with users. Once you correct the data detected in the training record, you mark the record as reviewed. The system then uses the reviewed training data when you rebuild the improved text analytics model.
