Recently Microsoft released “Microsoft Zo” the next generation chatbot. Have you ever felt you want to make it to?

I made a chatbot using a Japanese company’s AI chat service combined with Microsoft Azure Bot Services.

You can try it here: (Japanese only sorry)

You can add it on Skype too!

What to prepare

  • Microsoft Account
  • Skype
  • Azure Bot Service
  • Some chatbot service to link it to. (Japanese version available from here: http://ai.userlocal.jp/document/free/top

 

How to create it.

  • Go to Azure Portal, “New”, “Intelligence + Analytics”, “Bot Service” and click “Create”

  • You can acces what’s created by going to App Service

  • App type is shown as “Bot Service”

  • When you open it, it’ll ask you to create a Microsoft App ID. Click on “Create Microsoft App ID and Password”

  • Fill in the app name. App ID is auto generated. Click on create app password.

  • The password is shown. Make sure you make note of it to use it later and click ok once you’re ready to continue.

  • Go back to Bot Framework to continue.

  • Paste the App ID and password you took note of.

  • Select the programming language. We will use C# this time.

  • Next choose the template. We’ll use the basic template for today.
    Basic – A template with just a simple bot that counts the number of characters you’ve entered.
    Form – A questionnaire not using FormFlow.
    Proactive – A trigger based bot using Azure Functions triggers.
    Language understanding – Uses LUIS for natural language processing.
  • Once selected, the bot service will be deployed with the template.

  • Edit the coding like below to achieve what we want./div>
