QnA Maker is a cloud-based Natural Language Processing (NLP) service that enables developers to build, train and publish a sophisticated bot using FAQ pages, support websites, product manuals via a simple user interface or REST APIs. The ability to create and publish a bot without writing a single line of code helps in saving training costs for the organisation.

In addition to no code, Automatic extraction,Multi-turn conversations and scaling as per need provides an an opportunity to organisations to create a standalone system to cater to different needs of the company.

In this post, we will create a QnA Maker Service, a knowledge base and QnA Bot to interact with each and provide answers to FAQs entered by the user.
