Understanding Chatbots

To create successful chatbots using Alexa or Lex, you first need to understand the components that make up a chatbot. These parts can then be used to create conversation diagrams and flow diagrams, helping visualize the user's path through the conversation. Being able to have this map for the user's conversation makes building chatbots far easier and quicker.

Toward the end of the chapter, we will also introduce Alexa and Lex and have a look at their similarities and differences. We'll also have a quick look at some of the use cases for each of them.

The chapter will explain the following topics:

• Introducing chatbots
• Designing conversation flow diagrams
• Best practices
• Amazon Alexa and Amazon Lex
