Teneo Developers

Microsoft QnA Maker

The Teneo QnA Maker connector allows Teneo and Microsoft developers to connect a QnA Maker knowledge base with a Teneo solution. Teneo developers leveraging QnA Maker, which is part of the Azure Cognitive Services, will benefit from Microsoft’s state-of-the-art toolkit, which will allow them to develop a bot based on existing data in just minutes. In Microsoft’s own words, developers will be able to build, train, and publish sophisticated bots using FAQ pages, support websites, product manuals, SharePoint documents, or editorial content through an easy-to-use UI or via REST APIs.

At the same time, other related, more complex use cases can be built in Teneo, using Studio’s intuitive graphical UI and powerful flow builder, with support for 86 languages, multi-turn dialogues, context, custom channel behaviors, custom entities, sentiment analysis, and much more.

In this guide, we will explain how to get started in QnA Maker and seamlessly use a trained QnA Maker knowledge base within Studio.


The Teneo QnA Maker connector is made up of:

  1. A pre-built Teneo solution that contains the integration with Microsoft’s QnA Maker
  2. A sample QnA Maker knowledge base to get started

In order to use this solution, you will need a Azure subscription. Create a free account before you begin. You will also need a QnA Maker resource, created in the Azure portal. You will need to download and import the solution and download the QnA Maker knowledge base. See instructions on how to do this here.

Teneo QnA Maker Connector Solution

The following table lists and describes the contents of the solution.

MS QnA MakerFolderThis is a folder containing the main flow that handles questions about the QnA Maker knowledge base.
MS QnA Maker Connector FlowFlowThis flow retrieves the use-case-related question, stores it, and passes it to the QnA Maker integration, then extracts the response and passes it back to the user.
qnaMakerQuestionFlow variableThis flow variable stores the user question to be passed on to the integration.
qnaMakerAnswerFlow variableThis flow variable stores the response from the published QnA Maker knowledge base.
qnaMakerApiSubscriptionKeyGlobal variableThis global variable contains the QnA Maker Authorization Endpoint key, used as a header by the integration.
qnaMakerKbEndpointGlobal variableThis global variable contains the endpoint URL for the QnA Maker trained and published knowledge base, used as a header by the integration.
Follow up of flowScripted ContextThis global scripted context allows for a very seamless implementation of follow-up questions, like 'Who did Elvis marry?' followed by a related questions like 'When did he marry?'.
QnA Maker IntegrationIntegrationThe QnA Maker integration calls the QnA Maker API, passing the user request and retrieving the response, which is stored in a string variable for easy access within the flows.

Microsoft QnA Maker Knowledge Base

For this example, the knowledge base we will be using is an FAQ about Elvis Presley. The following instructions detail how to access and set up the knowledge base.

Sign up for an Azure Cognitive Services subscription

If you don’t have an Azure Cognitive Services subscription, go to Cognitive services and sign up for free. You can use the free tier to do everything that is included in this guide.

Set up a QnA Maker service in Azure

Before you can create any QnA Maker knowledge bases, you must first set up a QnA Maker service or resource in Azure. You will only need to do this once.

Here’s how:

  1. Go to Azure Portal.
  2. Follow Microsoft’s step-by-step guide to create a QnA service or resource in Microsoft Azure (find it here).

Microsoft QnA Maker 1 - setup

Create a new QnA Maker knowledge base

The next step will be connecting your QnA Maker service or resource to a new QnA Maker knowledge base.

  1. Go to QnA Maker.
  2. Refer to this Microsoft tutorial in order to create your own QnA Maker knowledge base.

Microsoft QnA Maker 2 - create KB

  1. Name your knowledge base.
  2. To populate your knowledge base, you will be able to skip the step of extracting data, as we have already created a knowledge base TSV file using the data from Graceland's FAQ page about Elvis. You don't need to do anything with this file just yet, as we will import it later, but you can download it here.

Microsoft QnA Maker 3 - skip populate

  1. Click on 'Create your KB' at the bottom.

Import knowledge base TSV

Once your knowledge base has been created, navigate to the 'Settings' section of your knowledge base:

  1. Under 'Settings', scroll down to 'Import knowledge base' and select 'QnAs'.
  2. Locate your ElvisFacts-QnAMaker-Kb.tsv file. !!! If you would like to create a different knowledge base from a website or by adding specific data files, feel free to replace this file with the new one.
  3. Click on 'Import knowledge base'.
  4. Navigate to the location where your TSV file is stored and select it.
  5. Click on 'Replace' when you see a message warning you about overwriting existing knowledge bases (you should have an empty knowledge base at this point).
  6. Wait until you see a message stating the import has been successful and click 'OK'.

You should be redirected to the 'Edit' section in your knowledge base and you should have a total of 27 QnAs about Elvis in your knowledge base at this point.

  1. Save and train your QnA Maker knowledge base by clicking on 'Save and train' at the top right corner to have your intents and answers created.

Publish your knowledge base

  1. Go to the 'Publish' section at the top and click on 'Publish':

Microsoft QnA Maker 4 - publish

  1. You should now see a message saying that the knowledge base has been published successfully, as well as a text field showing deployment details for a sample HTTP request in Postman and Curl. Under the 'Curl' tab, please copy the following information and store it somewhere, as you will need it later:
  • your POST URL (for example https://xxx.azurewebsites.net/qnamaker/knowledgebases/xxx/generateAnswer)
  • the value for Authorization: EndpointKey (for example kyhakr01eo2qxxxxx6p13h2y7ojm66)

Working on the Solution in Teneo

Now it is time to work on the solution inside Teneo in order to connect it to your Microsoft QnA maker.

Set up your Global configuration

Once your pre-built solution has been imported, please add your Lexical Resources (SOLUTION → Resources → Lexical), and then navigate to Globals and map the above values to these two Global Variables:

Variable NameExample ValueDescription
qnaMakerKbEndpointhttps://xxx.cognitiveservices.azure.com/qnamaker/v5.0-preview.2/knowledgebases/12345/generateAnswerPOST URL
qnaMakerApiSubscriptionKeykyhakr01eo2qxxxxx6p13h2y7ojm66Authorization Endpoint key

As an alternative to populating those Global Variables, you could also add those two parameters as input parameters in Try Out as in the following picture:

Microsoft QnA Maker 5 - tryout3

Test your MS QnA Maker flow

Your 'MS QnA Maker Connector Flow' will handle the extraction of the information and the connection with the integration. It will also allow you to provide different fallbacks if the user question is not found in the QnA Maker knowledge base or if the Global configuration has not been set up. The main trigger of your flow is based on Elvis-related keywords. Please remember to adapt your condition if your knowledge base is different.

Example Conversation

The following dialogue was created via QnA Maker, published as a knowledge base and available within Studio in less than 30 minutes, after extracting the information from Graceland’s FAQ page about Elvis: https://www.graceland.com/elvis-faq

User: When was Elvis born?
Bot: Elvis was born on January 8, 1935.
User: When did he die?
Bot: Elvis Presley passed away due to heart failure August 16, 1977, at Graceland in Memphis, Tennessee. He was 42 years old.
User: What was his first performance?
Bot: He first performed at Overton Park Shell on July 30, 1954.
User: And his first movie?
Bot: 'Love Me Tender' (1957) was Elvis' first movie.
User: How many movies did Elvis make?
Bot: Elvis made 31 feature films and 2 concert documentaries.


Please make sure that the solution you are importing this solution into does not have any Global Scripts at Pre-processing level. If it does, please make a backup of these scripts and add them back to your solution after the import.
