A new study has found that tweets from celebrities like Conan O'Brian, sometimes beat out news organizations and reigned as Twitter's top influencers on big news stories.
"The New York Times was the top influencer on the Gulf oil spill, which was the top topic of the year," said Alok Choudhary at Northwestern's McCormick School of Engineering and Applied Science.
"For the topic of Haiti, however, singer Adam Lambert was the most influential tweeter. For the Chilean miner rescue topic, comedian Conan O'Brian was the most influential, and singer Ricky Martin was number two."
"Adam Lambert tweeted for earthquake relief. Top influencers are very heavily dependent on the topic they are tweeting about and the area of the topic," said Choudhary, who created the website www.pulseofthetweeters.com, which analyzes data from Twitter in realtime.
Through www.pulseofthetweeters.com, Choudhary and his team use data mining, social network analysis and sentiment analysis to determine top influencers and sentiment distribution of the topics trending on Twitter.
A special algorithm ranks the most influential people tweeting on trending topics. To qualify as a top influencer on a topic, the user must actively tweet about the topic and have a following that also tweets about the same topic.
