Question answering provides cloud-based Natural Language Processing (NLP) that allows you to create a natural conversational layer over your data. It's used to find the most appropriate answer for any input from your custom knowledge base of information.
Prerequisites
- Configure the system fallback topic.
- Use Power Automate flows.
- Manage user credentials—If necessary you can set up authentication to use either author-supplied credentials, or user-supplied credentials.
Use question answering in fallback topic
You can use an existing knowledge base in Copilot Studio by using a Power Automate flow to connect it to any topic. However it's more useful to connect your knowledge base to your bot's system fallback topic. When a user asks a question that isn't covered by other topics, the bot can fall back to using content from your knowledge base.
To learn how to use the Question Answering Connector in a fallback topic, see Language - Question Answering.
