Twitter data 'predicts Boris Johnson victory'
The most recent opinion polls put Mr Johnson, who writes a column for The Daily Telegraph, four points ahead of his Labour rival, and the lead is seemingly reflected in online activity.
Lithium said its social network sentiment analysis tools predicted 54% of the vote for Mr. Johnson, on a head-to-head basis with Mr Livingstone. Dr. Michael Wu, Lithium's Principal Scientist of Analytics, said that using social network data to predict elections was in its infancy but had been shown to be accurate in US elections, including the recent Republican primaries.
