Abstract:In recent years, with the rapid growth of social network services (SNS), social networks pervade nearly every aspect of our daily lives. Social networks influence today's societal and cultural issues, and change the way people see themselves. To fully understand the running mechanisms of social networks, in this report, we aim at series of high knitted and important elements of online social networks. A social network is a social structure made up of a set of social actors (such as individuals or organizations) and a set of the ties between these actors. Existing researches on social network involve three perspectives: topological structure and its evolutioncrowds' interaction and mutual influenceinformation and its dissemination. In terms of structure and its evolution of social network, existing researches involve social network modeling, social network structure characteristic analysis, community detection and evolution theory.
