This is the web version part, where user can analysis their text or any written sentiment via the app. I've been using Logistic Regression Model since it's a fast and higher accuracy. And transferred it to web version with RESTapi. You can use this with your website. For rest API contact me via Email or LinkedIn.
If you want to run the app, you have to install python in your localhost. After that, follow the commands below..
