Mining bipartite graphs to improve semantic pedophile activity detection

Raphael Fournier, Maximilien Danisch
2014 2014 IEEE Eighth International Conference on Research Challenges in Information Science (RCIS)  
Pedophile activity is a very important topic for our society and some works have recently attempted to gauge the extent of pedophile exchanges on P2P networks.  ...  We propose to use social network analysis in a large dataset from a P2P network to improve a state-of-the-art filter for pedophile queries.  ...  Thus, the topological study of a bipartite graph between users and queries from a P2P network can help to improve and update a semantic filter.  ...
