Outline of Final Research Achievements

This research focuses on factors such as reputation, emotion, and ethics to realize a new method to detect cyber-bullying entries in unofficial school internet board.
On the basis of each factor, we designed modules to calculate harmful polarity. We conducted experiments for evaluation of our implemented modules with a test dataset based on harmful entries gathered from the internet. The results said that reputation and ethics are effective to calculate harmful polarity value although emotion has no correlation with harmful polarity.
On the whole, our method performs enough to reduce the load of net-patrol.
