Drawing the analogy from 'the arc reactor of the Ironman'. I had an idea to apply the same to a chatbot. An arc reactor for a chatbot that is made from assembling three main components  - Intents, Utterances and Response. 

The three components needed to build a chatbot - Intents, Utterances and Response

Assembling the three components make the arc reactor of the chatbot - The engine that works behind the chatbot

The shape of the arc reactor is analogous to a dialog from a chat window.
