On Differences in the Tagging Behavior of Spammers and Regular Users
نویسندگان
چکیده
In recent literature, several models have been proposed for reproducing and understanding the tagging behavior of regular users. Until now, they all have been evaluated by visually comparing their ability to reproduce characteristic properties found in tagging systems. This paper is the first which applies statistical methods for comparing the different tagging models and for measuring the statistical significance of the results. During our evaluation, we also show that spammers have a significant influence on the characteristic properties of tagging systems. This shows that they violate basic assumptions about regular user’s tagging behavior and thus existing models need to be extended for taking the behavior of spammers into account.
