Reputation and Trust in Social Networks: Empirical results from a Facebook Reputation system

Reputation systems play a key role in ensuring responsible online behavior in web properties and foster user participation. This paper examines the need for peer to peer social reputation system and shares the results from building a social reputation system for Facebook. The results indicate that for peer to peer social reputation systems it is a better practice to capture specific reputation scores at granular levels rather than high level reputation scores. We establish the importance of identity of entities in the success of peer to peer reputation systems. We also show that by combining both qualitative comments and quantitative scores, the reputation system gains in richness and diversity and helps capture much more information than the pre-defined questions
