PLOS: Under the Weather? How social media sentiments reflect weather patterns

PLOS: Under the Weather? How social media sentiments reflect weather patterns. “Grey skies getting you down? Research suggests that weather may impact our emotional state. But in a new PLOS ONE study, Patrick Baylis from the University of British Columbia, Nick Obradovich from MIT, and colleagues wanted to find out if specific weather conditions are associated with the positive or negative feelings expressed via social media. The researchers gathered 2.4 billion posts from Facebook and 1.1 billion from Twitter between 2009 and 2016. They used a categorization tool to analyze the sentiment for each post based on its positive and negative keywords. They also examined weather data for the location and date of each post to look for any associations.”
