Twitter time-laspe visualizes America's moods
Researchers from Northeastern and Harvard universities impressively gathered enough data from Twitter to generate a snapshot of how U.S. citizens feel throughout a typical day or week.
Not only did they analyze the sentiments we collectively expressed in 300 million tweets over three years against a scholarly word list, these researchers also mashed up that data with information from the U.S. Census Bureau, the Google Maps API and more. What they ended up with was a fascinating visualization showing the pulse of our nation, our very moods as they fluctuate over time.
Red means angry, orange means moderate, yellow means happier, green means happiest. Absolutely brilliant.
