Twitch Stream Chat Analyzer - HackSC Project

Created by likhity, eszabo12, victorphan101, and Mnv07 for HackSC 2022.

A chrome extension that analyzes the chat of a twitch stream and displays the percentage positivity of the chat, with 50% meaning a neutral positivity.

It gives twitch stream moderators an easy way to monitor the positivity of their stream and make sure the community is not too toxic without having to look at every chat.

How It Works

When the client's browser is currently on a twitch stream and the user clicks on the chrome extension, the client will connect to Twitch IRC. This is done using tmi.js.

The client will then send a stream of the chat to the server, which will perform a sentiment analysis of the chat stream and send back an update of the percentage positivity. The client will then render the percentage update on to the display in the chrome extension.

The user can input how many chats to analyze at a time. For example, if the user selects 50 as this input, every time a new chat arrives to the server, a new sentiment analysis of the last 50 chats is performed. A sentiment analysis on each single chat and returns the mean of the sentiment of all 50 chats.

The default number of chats it analyzes is 10.

This algorithm by which the percentage positivity is calculated still needs to be worked on, but it works well enough for demonstration purposes currently.

The server was built using Flask, and all of the client/server communication was done using Socket.io so that the user gets real-time updates.

The analysis of the chat stream was done using NLTK's Sentiment Intensity Analyzer.

Try It On Your Machine

To start, make sure you have Python 3.10 installed.

Install the necessary packages:

$ pip install nltk
$ pip install emoji
$ pip install numpy
$ pip install Flask
$ pip install Flask-RESTful
$ pip install Flask-SocketIO
$ pip install Flask-Cors

Clone the repository and start the server.

$ git clone https://github.com/likhity/twitch-stream-chat-analyzer.git
$ cd twitch-stream-chat-analyzer
$ cd server
$ python server.py

This will start the server on your local machine at http://127.0.0.1:5000/. Do not close the terminal.

Now, it's time to load the extension on chrome.

Go to chrome://extensions.

Make sure developer mode is on.

Now, click Load Unpacked.

This will open the file explorer on your computer.

Navigate to the hacksc project directory and open the client directory. <- IMPORTANT. Make sure you select and open the client directory (the directory that has a manifest.json file in it).

You will now have the extension loaded in chrome.

Now, open any active twitch stream in chrome.

Open the extension.

You should now see the stream's chat being analyzed in real time and the percentage positivity being updated with every new chat.

Conclusion

Developing this project was an absolute nightmare. Dealing with CORS issues and not being able to connect the browser successfully with the server was the bane of our existence.

We didn't eat, or sleep really, and kept working on this project trying to get a working product by the submission deadline.

We unfortunately didn't win but we all learned a lot. All of us went outside of our comfort zones, challenged ourselves, and worked with technologies and tools we never worked with.

However, the most important lesson we learned (or at least I did, can't speak for everyone) is: hackathons are really bad unless you go in person.
