Are Your Tweets Feeling Well?

Caption

Researchers at Pacific Northwest National Laboratory assigned more than 171 million anonymous tweets an opinion and emotion, such as "positive" and "joy." When visits to a certain health clinics for flu-related illnesses rose, the researchers found that opinion and emotion expressed by Twitter users in those regions also changed. Health workers could one day use this method to get real-time information about health trends.
