Introduction

 
In this article, I am going to explain how to create a conversational bot with zero lines of coding using QnA Maker- Azure Cognitive Service. 
 

What is Bot?

 
Bot stands for Build OperateTransfer. It is used to interact with humans conversationally. They automate the process of interacting with people on websites and social media.
 

QnA Maker 

 
QnA maker is a cloud-based API that is used to create a conversational bot using the data you provided in your knowledge base. It will extract the questions along with all possible answers from the data provided so that the chatbot manages the question from the user by giving them a correct answer.
