 This project aims to predict Big 5 personality traits from a sample of text using various Machine Learning models. A Facebook webscraper is included to scrape statuses of your Facebook friends to create a personality prediction for each of them. A Web App, Personality Analyzer, was created to interface with the predictions to compare your personality to your friends directly.
