An entity is used only for a single intent. Mixing of intent and entity definitions is considered a good practice. An intent represents a task or action the user wants to perform. It is a purpose or goal expressed in a user's utterance.The intent represents action the application should take for the user and is based on the entire utterance. An utterance can have only one top scoring intent but it can have many entities.
