Web Chatbot channel NLP model

The NLP model for the configured Web Chatbot channel is saved as a text analyzer rule. The Pega Intelligent Virtual Assistant for Web Chatbot uses this rule to analyze any text of the chat conversation for sentiment analysis, text (topic) classification, intent analysis, and entity extraction.

Each record item in the list represents a chat conversation with a customer that is saved by the channel. Each record item has an assigned topic that is used for text analysis. Only record items that generate no match or multiple matches text analyzer warnings are saved and appear on the Training data tab.

By updating the NLP model for the configured channel, you improve the machine learning capability for the channel instance. You send feedback from the Training data tab about the outcome of text analysis. When you edit a record item and match it with the expected outcomes, the subsequent text analysis results have a better confidence score, and the sentiment analysis, text (topic) classification, intent analysis, and entity extraction are more accurate.
