document: Influence and passivity in social media The ever-increasing amount of information flowing through Social Media forces the members of these networks to compete for attention and influence by relying on other people to spread their message . A large study of information propagation within Twitter reveals that the majority of users act as passive information consumers and do not forward the content to the network . Therefore , in order for individuals to become influential they must not only obtain attention and thus be popular , but also overcome user passivity . We propose an algorithm that determines the influence and passivity of users based on their information forwarding activity . An evaluation performed with a 2.5 million user dataset shows that our influence measure is a good predictor of URL clicks , outperforming several other measures that do not explicitly take user passivity into account . We demonstrate that high popularity does not necessarily imply high influence and vice-versa .
