URL 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.

URL entity extracts URLs with domain names or IP addresses. Because this entity is already trained, you do not need to add example utterances containing URLs to the application. URL entity is supported in en-us culture only.

Types of URLs

Url is managed from the Recognizers-text GitHub repository
