Azure QnA Maker will be retired on 31 March 2025. Beginning 1 October 2022, you won't be able to create new QnA Maker resources or knowledge bases. Custom question answering, a feature of Azure Cognitive Service for Language, is the updated version of the QnA Maker service.
QnA Maker is a cloud-based Natural Language Processing service that allows you to create a natural conversational layer over your data. It imports your content into a knowledge base of question and answer pairs. The import process extracts information about the relationship between the parts of your structured and semi-structured content to imply relationships between the question and answer pairs.
Prerequisites
- A Microsoft Copilot Studio bot
- Configure the system fallback topic
- A QnA Maker knowledge base
- 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 QnA Maker in fallback topic
You can use an existing QnA Maker knowledge base in Microsoft 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 QnA maker in a fallback topic, see Add your knowledge base to Microsoft Copilot Studio.
