QnA Maker

Bot Framework v4 QnA Maker bot sample

This sample shows how to create a bot that uses the QnA Maker Cognitive AI service.

Concepts introduced in this sample

The QnA Maker Service enables you to build, train and publish a simple question and answer bot based on FAQ URLs, structured documents or editorial content in minutes.

In this sample, we demonstrate how to use the QnA Maker service to answer questions based on a FAQ text file as input.

Prerequisites

  • [Node.js][4] version 8.5 or higher 
    # determine node version
node --version
  • QnA Maker service application
    • Follow instructions here to create a QnA Maker service.
    • Follow instructions here to import the smartLightFAQ.tsv to your newly created QnA Maker service.
    • Update qnamaker.bot with your QnAMaker-Host, QnAMaker-KnowledgeBaseId and QnAMaker-EndpointKey. You can find this information under "Settings" tab for your QnA Maker Knowledge Base at QnAMaker.ai.
    • (Optional) Follow instructions here to set up the qnamaker CLI tool to deploy the model.

To try this sample

  • Clone the repository 
    git clone https://github.com/microsoft/botbuilder-samples.git
  • In a terminal, navigate to samples/javascript_nodejs/11.qnamaker 
    cd samples/javascript_nodejs/11.qnamaker

Testing the bot using Bot Framework Emulator v4

Microsoft Bot Framework Emulator is a desktop application that allows bot developers to test and debug their bots on localhost or running remotely through a tunnel.

  • Install the Bot Framework emulator from here

Connect to bot using Bot Framework Emulator v4

  • Launch Bot Framework Emulator
  • File -> Open Bot Configuration and navigate to samples/javascript_nodejs/11.qnamaker
  • Select qnamaker.bot file

QnA Maker service

QnA Maker enables you to power a question and answer service from your semi-structured content.

One of the basic requirements in writing your own bot is to seed it with questions and answers. In many cases, the questions and answers already exist in content like FAQ URLs/documents, product manuals, etc. With QnA Maker, users can query your application in a natural, conversational manner. QnA Maker uses machine learning to extract relevant question-answer pairs from your content. It also uses powerful matching and ranking algorithms to provide the best possible match between the user query and the questions.

Deploy this bot to Azure
