Sentiment Analysis for Teams chat messages using Azure Open AI and messaging extension.

This sample shows a feature where user can analyze sentiments for messages posted in Teams chat using messaging extension and Azure Open AI.

Included Features

• ME
• Azure Open AI For Sentiment Analysis

Interaction with app

Prerequisites

• Microsoft Teams is installed and you have an account (not a guest account)
• csharp
• dev tunnel or ngrok (For local environment testing) latest version (any other tunneling software can also be used).
• M365 developer account or access to a Teams account with the appropriate permissions to install an app.

SECRET_AZURE_OPENAPI_KEY=<Azure OpenAI Service Key>

CHAT_COMPLETION_MODEL_NAME=gpt-3.5-turbo

Note: If you are deploying the code, make sure that above mentioned values are properly updated at env/.env.dev or env/.env.dev.user wherever required.

1. Select Debug > Start Debugging or F5 to run the app in a Teams web client.
2. In the browser that launches, select the Add button to install the app to Teams.

If you do not have permission to upload custom apps (sideloading), Teams Toolkit will recommend creating and using a Microsoft 365 Developer Program account - a free program to get your own dev environment sandbox that includes Teams.

Setup

Note these instructions are for running the sample on your local machine, the tunnelling solution is required because the Teams service needs to call into the bot.

1. Run ngrok - point to port 3978

   ngrok http 3978 --host-header="localhost:3978"

   Alternatively, you can also use the dev tunnels. Please follow Create and host a dev tunnel and host the tunnel with anonymous user access command as shown below:

   devtunnel host -p 3978 --allow-anonymous

3. Setup for Bot

In Azure portal, create a Azure Bot resource. - For bot handle, make up a name. - Select "Use existing app registration" (Create the app registration in Microsoft Entra ID beforehand.) - Choose "Accounts in any organizational directory (Any Azure AD directory - Multitenant)" in Authentication section in your App Registration to run this sample smoothly. - If you don't have an Azure account create an Azure free account here - In the new Azure Bot resource in the Portal, Ensure that you've enabled the Teams Channel - In Settings/Configuration/Messaging endpoint, enter the current https URL you were given by running the tunnelling application. Append with the path /api/messages

3. Setup for code

1. Clone the repository

   git clone https://github.com/OfficeDev/Microsoft-Teams-Samples.git

2. Open the code in Visual Studio

   • File -> Open -> Project/Solution
   • Navigate to folder where repository is cloned then samples/msgext-ai-sentiment-analysis/csharp/MEAISentimentAnalysis.sln

1. Update the appSettings.json configuration for the bot to use the MicrosoftAppId, SECRET_OPENAI_API_KEY and ApplicationBaseUrl with application base url. For e.g., your ngrok or dev tunnels url. (Note the MicrosoftAppId is the AppId created in step 1 (Setup for Bot), the MicrosoftAppPassword is referred to as the "client secret" in step 1 (Setup for Bot) and you can always create a new client secret anytime.)

Note: If you dont have access to Azure Open Api Key then use Open Api key.

• Press F5 to run the project.

5. Setup Manifest for Teams

• This step is specific to Teams.
  • Edit the manifest.json contained in the ./AppManifest folder to replace your Microsoft App Id (that was created when you registered your app registration earlier) everywhere you see the place holder string {{Microsoft-App-Id}} (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json)
  • Edit the manifest.json for validDomains and replace {{domain-name}} with base Url of your domain. E.g. if you are using ngrok it would be https://1234.ngrok-free.app then your domain-name will be 1234.ngrok-free.app and if you are using dev tunnels then your domain will be like: 12345.devtunnels.ms.
  • Zip up the contents of the AppManifest folder to create a manifest.zip (Make sure that zip file does not contains any subfolder otherwise you will get error while uploading your .zip package)
