    Talk Title: Multimodal Labeling and Characterization of Social Network Data for Detection/Prediction of Cyberbullying

    Abstract: One of the most pressing problems in high schools is bullying. However, with todays online and mobile technologies, bullying is moving beyond the schoolyards via cell phones, social networks, online text, videos, and images. As bad as fighting and bullying were before the internet age, the recording and posting of hurtful content online have magnified the harmful reach of bullying, enabling it 24 7. Cyberbullying is a growing problem and incidents of cyberbullying with extreme consequences such as suicide are routinely reported in popular press now. This talk provides insights into the problem of cyberbullying in social networks by investigating profanity usage, ground truth labeling of cyberbullying, and characterization of relationships between cyberbullying and a variety of factors, including linguistic content, social graph features, temporal commenting behavior, and multimedia modality. It also looks at the propagation of cyberbullying behavior in a social network, and prediction of victims of such behavior.
