What is QnA Maker?

QnA Maker enables you to power a question and answer service from your semi-structured content like FAQ (Frequently Asked Questions) documents or URLs and product manuals. You can build a model of questions and answers that is flexible to user queries, providing responses that you'll train a bot to use in a natural, conversational way.

An easy-to-use graphical user interface enables you to create, manage, train and get your service up and running without any developer experience.

Overview

Highlights

  • A complete no-code experience to create a FAQ bot.
  • No more network throttling. Pay for hosting the service and not for the number of transactions. See the pricing page for more details.
  • Scale as per your needs. Choose the appropriate SKUs of the individual components that suit your scenario. See how to choose capacity for your QnA Maker service.
  • Full data compliance. The data and runtime components are deployed in the user's Azure subscription and within their compliance boundary. Read below for more details.

Key QnA Maker processes

A QnA Maker provides two key services for your data:

  • Extraction: Structured question-answer data is extracted from semi-structured data sources like FAQs and product manuals. This extraction is done when creating the knowledge base. Create your knowledge base here.

  • Matching: Once your knowledge base has been trained and tested, you publish it. This enables an endpoint to your QnA Maker knowledge base, which you can then use in your bot or app. This endpoint accepts a user question and responds with the best question/answer match in the knowledge base, along with a confidence score for the match.

QnA Maker architecture

The QnA Maker stack consists of the following parts:

  1. QnA Maker management services (control plane): The management experience for a QnA Maker knowledge base, which includes the initial creation, updating, training, and publishing. These activities can be done through the portal or the management APIs. The management services talk to the runtime component below.

  2. QnA Maker runtime (data plane): The data and runtime are deployed in the user's Azure subscription in a region of their choosing. Customer question/answer content is stored in Azure Search, and the runtime is deployed as an App service. Optionally, you can also choose to deploy an Application insights resource for analytics.
