Conversation Language Understanding (CLU) Recognizer

Summary

This recognizer helps you add a custom recognizer to an empty bot built with Bot Framework Composer in order to use the Conversation Language Understanding Service in place of the now deprecated LUIS.

Installation

In order to enable the CLU recognizer, you must first install the CLU recognizer package from NPM in your Composer project.

1. Create a new Composer bot using the Empty Bot template.

2. Open the Package Manager in Composer.

3. Search for ConversationLanguageUnderstandingRecognizer and install the package.

Configuration

To enable the Conversation Language Understanding recognizer, complete the following steps:

1. Select Custom as your root dialog's recognizer type.

2. Paste the following JSON into the custom recognizer configuration window:

{
  "$kind": "Microsoft.CluRecognizer",
  "projectName": "<your project name>",
  "endpoint": "<your endpoint, including https://>",
  "endpointKey": "<your endpoint key>",
  "deploymentName": "<your deployment name>"
}

3. Update the projectName, endpoint, endpointKey, and deploymentName fields with the values from your Conversation Language Understanding service.

   • The deploymentName value can be found in the Deploying a model blade under Deployments inside Language Studio.

   • The endpoint value can be found in the Deploying a model blade under Deployments inside Language Studio by clicking on the Get prediction URL option. It can also be found in the Keys & Endpoint blade of your Language resource in the Azure Portal. The endpoint should take the format https://<language-resource-name>.cognitiveservices.azure.com. Ensure that the trailing slash is omitted.

   • The projectName and endpointKey values can be found in your Project Settings blade under Azure Language Resource inside Language Studio.

Ensure that you have selected the correct values for each field. Using the wrong values can lead to errors when running the bot.

Usage

Once you have configured intents and entities in your Conversation Language Understanding project, custom intent triggers and the CLU intent triggers should function as normal. When creating a new intent trigger in a Composer bot, make sure that the intent value of the trigger matches the intent in the deployed Language resource (case-sensitive).

Since the Conversation Language Understanding recognizer is a modified version of the existing LUIS recognizer, the workflow elements work the same. In addition the respective LUIS events and telemetry are written out to the logs.

Limitations

Please remember that Composer does not integrate natively with Conversation Language Understanding, so managing intents and entities must be done in the Language Studio portal instead of Composer.
