Defining advanced WebChat text analyzer configuration

In the advanced text analyzer configuration for a WebChat channel, you can specify several text analyzer definitions to provide the best response to users. User input is analyzed by the first text analyzer definition in the list, and if no match is found, the second text analyzer definition in the list, and so on, until a response is found.

You can specify whether each text analyzer runs within the context of a case, outside of the context of a case, or both. For example, if you have a case that allows users to buy airline tickets, you can run a text analyzer definition within the context of a case so that when the chatbot asks the user about when to book the flight, the response is automatically converted to a specific date.

Note: You must purchase a separate license before using Pega Intelligent Virtual Assistant for WebChat in your application.
