US researchers at Northeastern University, Boston, have shown the potential value of the millions of messages on Twitter.
They created a Twitter Mood Map to measure the mood in the country. The research highlights how information can be derived by aggregating and analysing the millions of tweets. Researcher Sume Lehmann explains:
Even though individual tweets are pointless to anyone besides your followers, in aggregate there is a lot of meaningful information that can be an instrument to see how people feel about things, whether it’s public reaction to a politician’s speech or a consumer attitudes about a brand.
