Language Understanding (LUIS) Samples

Welcome to the Language Understanding (LUIS) samples repository. LUIS allows your application to understand what a person wants in their own words. LUIS uses machine learning to allow developers to build applications that can receive user input in natural language and extract meaning from it.

Create your Azure LUIS service

Use the Deploy to Azure button to quickly create an Azure LUIS service. You get one free LUIS service per account. The free service has a sku of F0. The basic tier has a sku of S0.

Interactive app

Ask LUIS to turn on the lights in this interactive demonstration.

Healthbot

Tell the Contoso Health bot where you are injured and the bot will recommend remedies.

Intelligent Kiosk

The open-source Intelligent Kiosk Sample version is a collection of apps showcasing workflows and experiences built on top of the Microsoft Cognitive Services. Most of the experiences are hands-free and autonomous, using the human faces in front of a web camera as the main form of input (thus the word "kiosk" in the name).

Install the currently supported Intelligent Kiosk as a Windows 10 app and try out the various apps inside the kiosk, including apps with LUIS.
