IBM has created an AI platform named Watson that gives businesses and developers access to powerful tools for text and speech analysis, computer vision, and more. Watson APIs consist of a suite of services used to process or analyze data to answer questions and make decisions. This course will show you how to build a chatbot with Node.js and the Conversation and Discovery services from Watson. You'll also learn how to setup your bot on the IBM Cloud platform.
What you'll learn
Set up personal Watson API instances on IBM Cloud
Send and receive data from Watson APIs
Process text using the Watson Conversation service
Process text using the Watson Discovery service
Configure a conversational dialog with intents and entities
Introducing the Watson APIs
IBM Watson is a platform of APIs that IBM has trained on immense data sets for use as a service. The Watson APIs allow you to process speech, text, and images in an easy and natural way. They also allow you to further train services with your own custom data to provide context-specific analysis. In this stage we'll get a good feel for what you can build with Watson APIs.

Review: What is Watson?
Using the Conversation Service
The heart of our chatbot is built using Watson's Conversation APIs. In this stage we'll build and test a custom Conversation Service and see how it is used from our client app.

Using the Discovery Service
The real fun and power of the Watson platform happens when we start combining multiple services together to create more context-aware and capable systems. In this stage we will setup and integrate the Discovery API, which allows us to gather insights from unstructured or loosely defined data sets.
