Abstract

Through online social network analysis, the emergence (over time) of “trusted” users is investigated, by studying the evolution of topological and centrality measures of the network of trust within the overall social network. Large datasets of user activity are studied from Ciao and Epinions (two online platforms with an explicit notion of trust controlled by users), and Prosper (a micro-lending site where trust remains implicit). The implications of such findings are discussed, particularly regarding how to enable trust in online platforms and interaction, with implications for trust-based activities.
