An algorithm that takes as input the co-review graph of an app A, and outputs its “fraud components”
An algorithm that partitions a co-review graph into components, each controlled by a different worker. MCDense exploits the observation that the accounts controlled by a worker are likely to be used to review many products in common, while two accounts controlled by different workers are unlikely to have reviewed many products in common.
