How Amazon Lex Works?

When the chatbot receives an input it either replies with a relevant message or it will complete the desired task for the user.

The Amazon Bot

An artificial intelligence program that simulates an interactive conversation.


An intent represents an action that the user wants to perform for example if you want to order a service then ordering the service is your intent and every intent has a descriptive name. It has utterances which means how you want to convey your intent for example if you want to order a service you can say can I order a service? Or do I want to order a service?


Slots are petameters that intent might require for example if you want to order or buy a service you need to specify a service name, its type, and other specifications that serve nothing but a slot.


Every slot has a slot type; you can go and create a built-in or custom slot type.

For example, if you consider a service type then you have development tools, databases, storage, networking, migration, etc.

Intent Fulfilment

It is nothing but how you want to fulfill the intent after the user provides the necessary information.
