My library Knowledge Sources To Go is very popular, but it was intended mainly as a thematically grouped guide to standard sources and was provided by me as a PDF file. For certain topics, however, there is so much content that I can no longer include it in that document, as it cannot continue to grow forever.
For this reason, I have decided to handle such topics in individual community articles like this one instead.
What is Natural Language Understanding?
Natural Language Understanding provides a workbench and an NLU inference service that you can use to enable the system to learn and respond to human-expressed intent. By entering natural language examples into the system, you help it understand word meanings and contexts so it can infer user or system actions.

Refer to this documentation so you are up to date with changes to the NLU Service.

Below is another way to migrate several Virtual Agent topics without using a scoped app.
