ELI5: Explain Like I'm 5

Emotion Markup Language

Emotion markup language is a way to describe how people are feeling. It uses words, symbols and numbers to show how someone is feeling. For example, you might use a heart to say that someone is feeling happy or a sad face to say someone is feeling sad. You can also use numbers like '1' for very sad and '10' for very happy. It lets us talk about our feelings in a clear way.
