- 1276 abstract "This paper aims to identify the most respected, authoritative members of a large-scale online social network by constructing a global ranked list of the network's members. We notice that the information about people's importance can come from two sources: (a) invitations to connect, which are usually sent to people whom the inviters respect; (b) members' browsing behavior, as profiles of more important people are viewed more often than others. We construct two directed graphs over the same set of nodes (which are member profiles): the graph of invitations and the graph of navigation. We show that the standard Pagerank algorithm, a baseline in Webpage ranking, is not effective in people ranking, and develop a tournament-based Pagerank version, called the fair bets, as a viable solution. We then propose a novel approach, which we call bimodal fair bets, that leverages both the invitation and navigation graphs by simultaneously using the fair bets scores of nodes in each graph to provide the teleportation vector for the other graph. We evaluate the ranking results on the LinkedIn social network, where members who have Wikipedia profiles are assumed to be authoritative.".
