Anu Shresta, Francesca Spezzano, and Maria Soledad Pera. 2018. “Who is Really Affected by Fraudulent Reviews?: An analysis of shilling attacks on recommender systems in real-world scenarios”. In Proceedings of the 12th ACM Conference on Recommender Systems (RecSys 2018 Late-Breaking Results).
We present the results of an initial analysis conducted on a real-life setting to quantify the effect of shilling attacks on recommender systems. We focus on both algorithm performance as well as the types of users who are most affected by these attacks.
