Prebuilt entities to recognize common data types

LUIS includes a set of prebuilt entities for recognizing common types of information, like dates, times, numbers, measurements, and currency.

Add a prebuilt entity

  1. Open your app by clicking its name on My Apps page, and then click Entities in the left side.

  2. On the Entities page, click Add prebuilt entity.

  3. In Add prebuilt entities dialog box, select the datetimeV2 prebuilt entity.

    Add prebuilt entity dialog box

  4. Select Done.

Publish the app

The easiest way to view the value of a prebuilt entity is to query from the published endpoint.

  1. In the top toolbar, select Publish. Publish to Production.

  2. When the green success notification appears, select the Refer to the list of endpoints link to see the endpoints.

  3. Select an endpoint. A new browser tab opens to that endpoint. Keep the browser tab open and continue to the Test section.

Test

After the entity is added, you do not need to train the app.

Test the new intent at the endpoint by added a value for the q parameter. Use the following table for suggested utterances for q:

Test utterance Entity value
Book a flight tomorrow 2018-10-19
cancel the appointment on March 3 LUIS returned the most recent March 3 in the past (2018-03-03) and March 3 in the future (2019-03-03) because the utterance didn't specify a year.
Schedule a meeting at 10am 10:00:00
