Custom Question Answering Recognizer

Summary

This recognizer helps you add a custom recognizer to an empty bot built with Bot Framework Composer in order to use Azure Custom Question Answering in place of the now deprecated QnA Maker.

Installation

Once you've installed the package using Bot Framework Composer, you can add our actions and triggers to your bot.

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

2. Open the Package Manager in Composer.

3. Search for custom-question-answering-recognizer and install the package.

Configuration

To enable the Custom Question Answering 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.CustomQuestionAnsweringRecognizer",
  "hostname": "<your endpoint, including https://>",
  "projectName": "<your project name>",
  "endpointKey": "<your endpoint key>"
}

3. Update the hostname, projectName, and endpointKey fields with the values from your Custom Question Answering service.

   • The hostname and endpoint key can be found in the Keys & Endpoint blade in the menus for your Azure Language Service in the Azure Portal
   • The project name can be found in your 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 question and answer pairs in your Custom Question Answering project, custom intent triggers and the QnA intent triggers should function as normal.

Since the Custom Question Answering recognizer is a modified version of the existing QnAMaker recognizer, the workflow elements (such as multi turn) work the same. In addition the same QnAMaker events and telemetry are written out to the logs.

Limitations

Please remember that Composer does not integrate natively with Question Answering, so managing question and answer pairs must be done in the Language Studio portal instead of Composer.
