Tl;Dr: An Infograph

I have prepared an infographic summarizing this post, you can find it below. Feel free to save the chatbot vocabulary infographic and share it with your team. For more detailed definitions and examples, scroll along.


A chatbot is a computer program designed to simulate human conversation. Chatbot interprets the words given to them and provides a pre-set answer.

An intent represents the purpose of the user input. It is the reason why the user is sending a message to the chatbot.

Chatbot Intent Examples:

What is the price?
What is the cost?
How much does it cost?


An entity represents details that compliment the intent. Entities are used to identify and extract useful information from natural language data. Chatbot Entities can be a date, time, email, phone number, location, etc.

Chatbot Entity examples:

When is Tesla coming to India?Tesla, India
What is the price for Model S?Model S
Book a demo for tomorrowtomorrow


An utterance is the smallest unit of speech. It is a continuous piece of speech, beginning and ending with a clear pause. Chatbot Utterances are the inputs from the user to the chatbot.

Utterances example
Moving home
I am moving home
Shifting to a new place


The context in chatbot refers to the current state of the conversation. Unlike intent and entities, which are associated with a single user message, context is about the conversation happening across multiple messages.

Chatbot context remembers the previous history and understands the purpose of the chat.

Conversation example that shows how context is used.
How may I help you?Book a flight for Bangalore
When do you want to fly?Tomorrow
There are 2 flights available for tomorrow at 11 AM and 4 PM, which one you want to book?11 AM
Thank you for the confirmation. Your flight is booked. Your flight for Bangalore will depart from LA on 20 Jan 2021 at 11 AM. 

Here, the chatbot remembers the context from the history of the conversation.

Natural Language Processing (NLP)

  • Natural Language refers to the way humans communicate with each other. Natural Language Processing (NLP) is broadly defined as the electronic manipulation of natural language, like speech and text, by software.

Artificial Intelligence (AI) Chatbot

Artificial Intelligence (AI) chatbots are chatbots that understand and answer more complex queries. The AI-powered chatbot uses Natural Language Processing to break down the user sentence into Intent and Entities. Intents and Entities information along with context is used to generate the response in the AI-powered chatbot.
