keyPhrase prebuilt entity for a LUIS app

Important

LUIS will be retired on October 1st 2025 and starting April 1st 2023 you will not be able to create new LUIS resources. We recommend migrating your LUIS applications to conversational language understanding to benefit from continued product support and multilingual capabilities.

The keyPhrase entity extracts a variety of key phrases from an utterance. You don't need to add example utterances containing keyPhrase to the application. The keyPhrase entity is supported in many cultures as part of the Language service features.
