Ordinal prebuilt entity for a LUIS app

2025-06-13

Important

Language Understanding Intelligent Service (LUIS) will be fully retired on March 31, 2026. LUIS resource creation isn't available. Beginning on October 31, 2025, the LUIS portal will no longer be available. 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

Order the second option

The following JSON is with the verbose parameter set to false:

"entities": {
    "ordinal": [
        2
    ]
}

The following JSON is with the verbose parameter set to true:

"entities": {
    "ordinal": [
        2
    ],
    "$instance": {
        "ordinal": [
            {
                "type": "builtin.ordinal",
                "text": "second",
                "startIndex": 10,
                "length": 6,
                "modelTypeId": 2,
                "modelType": "Prebuilt Entity Extractor",
                "recognitionSources": [
                    "model"
                ]
            }
        ]
    }
}

The following example shows the resolution of the builtin.ordinal entity.

"entities": [
  {
    "entity": "second",
    "type": "builtin.ordinal",
    "startIndex": 10,
    "endIndex": 15,
    "resolution": {
      "value": "2"
    }
  }
]
