Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for detecting suspicious user activities. One of the methods includes generating hypergraphs, wherein the hypergraphs include nodes corresponding to feature profiles and edges between particular nodes representing a measure of similarity between nodes; using the generated hypergraphs to detect suspicious graph nodes; and using the suspicious graph nodes to detect malicious user communities.
