Codeforces Comment Extension

This is a React Chrome extension that classifies comments to relevant problems in the Codeforces tutorial pages.

This extension is still under development.

NOTE

• Currently, only the without-ml branch is functional. It classifies comments based on pattern search. Though not perfect, it provides decent results. Please use this branch.
• You need to have nodejs, npm and react installed.

Install

1. Clone this repository
2. Install packages and build

npm install  
npm run build

This generates a build folder.

3. Load the extension to your browser.

• Go to the Extensions page.
• Enable developer mode.
• Click Load unpacked.
• Select the build folder that was generated.

Use

• Go to a tutorial page on Codeforces. A sidebar appears with the list of problems, and a preview of relevant comment threads for each problem.
• Click on the preview of any comment to scroll to that thread. The comment is highlighted in yellow for a second to help you find it.

Things to be added / fixed

• An option to hide / show the sidebar
• Use a combination of ML and pattern search to make the results better.
• Currently, only the first comment of a thread is considered for classification. We must find a way to consider the entire comment thread for classification.
• Improve extraction of text from comment when it contains links, images and so on.
• Use upvotes/downvotes to sort the results.
