QnA Maker is an API service that can be used to create bots without writing any code. You can add personality to the bots based on the inbuilt chit chat data sets. The software also helps you extract pairs of question-answers from different semi-structured content. You can use the REST APIs or QnA Maker portal to design sophisticated multi-turn conversations. The active learning module in QnA Maker helps you improve your ranking model. You can also scale the generated bots as per requirement.
