Abstract

Online reviews play a significant role in users' purchasing decisions. In order to improve their reputation or degrade their competitors' products, some sellers employ a large numbers of review spammers to write fake reviews systematically and strategically to mislead potential consumers. In order to detect such organized spammer groups, this paper proposed a group spam detection algorithm that comprehensively considered the network structure and the behavior characteristics of reviewers. In implementation, this algorithm first obtained the closeness between reviewers based on the relevance of ratings and review time, and constructed a reviewer relationship graph. Secondly, based on the constructed reviewer relationship graph, it used label propagation method to detect the community and got a set of candidate groups. Finally, it restored the corresponding bipartite graphs of the candidate groups, and then found the final spammers on each bipartite graph by taking contrast suspiciousness as a metric. Experimental results based on real datasets demonstrate the effectiveness of the proposed algorithm.
