Twitter political index launches for US election
WASHINGTON (AFP) - Twitter on Wednesday launched a new political index aimed at gauging the 2012 United States presidential race by analysing daily tweets.
In the first release, the index gave US President Barack Obama a score of 34 - down four points from the previous day - to 25 for Republican rival Mitt Romney, who was up two points.
But a historical look at the index since May 1 showed wide variation, with Mr Obama's score ranging from 10 to 74 and Mr Romney's from 14 to 64.
The index is calculated with a company called Topsy, which provides "real-time social analytics" by analysing tweets to calculate a daily score measuring how Twitter users feel about the presidential candidates.
