Azure Bot Service – QnA Maker

Use your existing content to build and train a simple question-and answer-bot that responds to users in a natural, conversational way. Ingest FAQ URLs, structured documents, and product manuals and extract all possible question-and-answer pairs from the content. Edit, remove, or add question-and-answer pairs with a simple-to-use interface, then publish your knowledge base as an API endpoint for a bot service. Easily test and train the bot using a familiar chat interface. Scale your service according to your business and compliance needs, and expand your options by integrating with other APIs.
