Abstract

Social Networks (SN) are created whenever people interact with other people in online social networks, such as Twitter, Google+, Facebook and etc. Twitter is a social networking and micro-blogging service; it creates several new interesting social network structures. In this sense, our main goal is to investigate the power of retweet mechanism. The findings suggest that relations of "friendship" at Twitter are important but not enough. Still, the centrality measures of a node importance do not show how important users are. We uncovered some other principles that must be studied like, homophily phenomenon, the tendency of individuals to associate and bond with similar others.
