How might short linguistic expressions help reveal our underlying emotional states? Our team is trying to find out. We’ve combined a crowdsourced tweet-rating tool with a website that displays a state-of-the-art sentiment classifier created by my colleagues. Our goal is to collect as many user-rated tweets as possible and to generate a validated emotion classification algorithm. If interested, help us out! This project is in collaboration with Bjarke Felbo, Holly Shablack, Kristen Lindquist and Iyad Rahwan.
