Verifying detected topics and entities
To ensure that Pega Intelligent Virtual Assistant™ (IVA) responds correctly to user requests during a chat session, you can first simulate conversations with the chatbot and then verify the detected information in the preview console for a conversational channel. As a result, the system becomes more responsive and improves its text analysis and artificial intelligence.
For example, you can verify that the system correctly detects the topic related to car insurance, the subject matter, and detects a car model and make, when a user asks for a car insurance quote for their car in the chat session.- In the navigation pane of App Studio, click Channels.
- In the Current channel interfaces section, click the icon that represents your existing Digital Messaging or Alexa channel.
- In the channel, click the Behavior tab.
- If you configure multiple languages for the chatbot, at the top-right of the preview console, select a language.
- Turn on the Show analysis switch.
- In the preview console in the right panel, type in a typical user phrase that starts a business case.
