Five months with the Devils: Identifying Content Polluters in Social Streams By RadinaKalpakova
Why would it matter? • Problem gaining popularity but not yet well understood • Can cause severe implications on society – vandalism, protests,rebellions • 2.0 security for 2.0 websites • Legal issues involved – Freedom of speech • Attempt of preserving high quality content on the web.
How can we identify content polluters in Social Streams Accurately? • What drives polluters’ behavior? Why are they doing it? What are their motives? • What distinguishes polluters from legitimate users? • How can we detect them?
How would we solve it? • Analyze and identify differences between the behavior of polluters and legitimate users • Create a set of polluters profiles based on chosen features – relationship with other users, posting frequency and content, interaction with other users, web links posted, reputation, etc. • Set social honeypots to attract potential polluters • Experiment with various classification approaches with the aim to find the optimum features that maximize the classification results (social graph modeling, feature selection etc. )
