Combating Spam in Tagging Systems

Koutrika, Georgia and Effendi, Frans and Gyongyi, Zoltan and Heymann, Paul and Garcia-Molina, Hector (2007) Combating Spam in Tagging Systems. Technical Report. Stanford.




Tagging systems allow users to interactively annotate a pool of shared resources using descriptive tags. As tagging systems are gaining in popularity, they become more susceptible to tag spam: misleading tags that are generated in order to increase visibility of some resources or simply to confuse users. We introduce a framework for modeling tagging systems and user tagging behavior. We also describe a method for ranking documents matching a tag based on taggers' reliability. Using our framework, we study the behavior of existing approaches under malicious attacks and the impact of a moderator and our ranking method.
