Building an Amazon Lex chatbot

You can create an Amazon Lex chatbot within a web application to engage your web site visitors. An Amazon Lex chatbot is functionality that performs on-line chat conversation with users without providing direct contact with a person. For example, the following illustration shows an Amazon Lex chatbot that engages a user about booking a hotel room.

The Amazon Lex chatbot created in this Amazon tutorial is able to handle multiple languages. For example, a user who speaks French can enter French text and get back a response in French.

Likewise, a user can communicate with the Amazon Lex chatbot in Italian.
