Ordinal 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.

Ordinal number is a numeric representation of an object inside a set: first, second, third. Because this entity is already trained, you do not need to add example utterances containing ordinal to the application intents. Ordinal entity is supported in many cultures.

Types of ordinal

Ordinal is managed from the Recognizers-text GitHub repository
