Age 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 prebuilt age entity captures the age value both numerically and in terms of days, weeks, months, and years. Because this entity is already trained, you do not need to add example utterances containing age to the application intents. Age entity is supported in many cultures.

Types of age

Age is managed from the Recognizers-text GitHub repository
