Bot Framework v4 core bot sample.

This bot has been created using Bot Framework, it shows how to:

• Use LUIS to implement core AI capabilities
• Implement a multi-turn conversation using Dialogs
• Handle user interruptions for such things as Help or Cancel
• Prompt for and validate requests for information from the user

Prerequisites

This sample requires prerequisites in order to run.

Overview

This bot uses LUIS, an AI based cognitive service, to implement language understanding.

• Node.js version 10.14 or higher

  # determine node version
  node --version

Create a LUIS Application to enable language understanding

The LUIS model for this example can be found under cognitiveModels/FlightBooking.json and the LUIS language model setup, training, and application configuration steps can be found here.

Once you created the LUIS model, update .env with your LuisAppId, LuisAPIKey and LuisAPIHostName.

LuisAppId = "Your LUIS App Id"
LuisAPIKey = "Your LUIS Subscription key here"
LuisAPIHostName = "Your LUIS App region here (i.e: westus.api.cognitive.microsoft.com)"

To try this sample
