Robots have amazed us for generations. With the correct combination of technology and need, Chatbots are the new buzzword. In this post, we will discuss in detail about what is Chatbot, its various types, how it works, its applications, advantages as well as disadvantages.

What is Chatbot

A chat robot (sometimes referred to as a Chatterbot) is a programmed module that simulates the conversation or “chatter” of a human being through text or voice interactions. Typically, a Chatbot will interact with a real person.

Introduction to Chatbot

Chatbot virtual assistants are being used to handle simple, look-up tasks in both business-to-business (B2B) and business-to-customer (B2C) environments. The addition of Chatbots not only reduces overhead costs by making better use of support staff time, but it also allows companies to provide customer service during hours when live agents aren’t available.

How a Chatbot Works

There are two different tasks of a Chatbot:

  • User Request Analysis
  • Returning the Response

As you can see in above image, a Chatbot returns a response based on input from a user. This process may look simple but in practice, things are quite complex.

User Request Analysis

This is the first task for a Chatbot. It studies the user’s request to identify the user intent and to extract relevant entities. Ability to recognize the user’s intent and extract data and relevant entities contained in the user’s request is the priority condition and the most relevant step of a Chatbot. If you are not able to correctly identify the user’s request, you won’t be able to provide the correct answer.

Returning the Response

Once the user’s intent has been identified, the Chatbot must provide the most accurate response for the user’s request. The answer can be:

  • A generic and predefined text.
  • A text received from a knowledge base that contains different answers.
  • A piece of information based on data the user has provided.
  • The result of an action that the Chatbot performed with one or more backend application.

Types of Chatbot

There are two types of Chatbots:

Artificial Intelligence Based Chatbots
