Cyberbullying, or humiliating and slandering people through Internet, has been recently noticed as a serious social problem disturbing mental health of Internet users. In Japan, to deal with the problem, voluntary members of Parent-Teacher Association (PTA) manually read through the Web to spot cyberbullying entries. To help PTA members in their uphill task we propose a novel method for automatic detection of malicious contents on the Internet. The method is based on a combinatorial approach resembling brute force search algorithms with application to language classification. The method extracts sophisticated patterns from sentences and uses them in classification. We tested the method on actual data containing cyberbullying provided by Human Rights Center. The results show our method outperformed previous methods. It is also more efficient as it requires minimal human effort.]]>
