IT TURNS out those 140-character tweets on Twitter can tell you a lot about the mood of the world.
 
Researchers have analysed 509 million posts on the micro-blogging website for more than two years, covering 2.4 million users and 84 countries, including Australia.
 
“Text analysis of these messages provides a detailed measure of individuals’ spontaneous affective expressions across the globe,” the US-based researchers reported.
 
“We found that individuals awaken in a good mood that deteriorates as the day progresses – which is consistent with the effects of sleep and circadian rhythm.”
 
The study used software to rate each tweet for its positive or negative affect – PA vs NA – a process which separated tweets indicating “enthusiasm, delight, activeness or alertness” from those showing “distress, fear, anger, disgust”.
