ICWSM 2018 Tutorial
Characterization, Detection, and Mitigation of Cyberbullying
by Charalampos Chelmis and Daphney-Stavroula Zois

Tutorial information

Bullying, once limited to physical spaces (e.g., schools, workplaces or sports fields) and particular times of the day (e.g., school hours), can now occur anytime, anywhere. Cyberbullying can take many forms; however, it typically refers to repeated and hostile behavior performed in an effort to intentionally and repeatedly harass or harm individuals. The consequences of cyberbullying can be devastating.

This tutorial presents a systematic review of approaches to detect, characterize, and mitigate cyberbullying behavior on online social media. First, we discuss the concept of cyberbullying, and the related nomenclature, by drawing from the social and psychological sciences. Then, we perform an in–depth review of the state–of–the–art cyberbullying research. We characterize the phenomenon of bullying on social media, and present recent computational approaches for the detection, quantification, and mitigation of cyberbullying. We subsequently discuss the role of content and network structure of online social media interactions to these ends.

Throughout the tutorial, we highlight the open challenges that need to be addressed in understanding, predicting, and preventing cyberbullying behavior, as well as promising research directions for researchers interested in this area.

The tutorial will be held at the 12th International AAAI Conference on Web and Social Media in Stanford, California, USA on June 25th, 2018.

Materials for the Interactive Session

The tutorial includes an interactive session focused on exploring different types of bullying online and the effects of human annotation on cyberbullying detection. Participants will jointly evaluate (and engage in discussion) with the tutors sample content from Twitter and Instagram. Please find the worksheets for this session here.

Who should attend

This tutorial targets academic, industry and government researchers and practitioners with interest in user behavior modeling, social media and social network analysis, graph mining, and detection and prediction algorithms. Beginners will learn the basics of state–of–the–art methods in this area, whereas experts in the area will have a chance for an in–depth review of both platform–specific techniques and platform–independent algorithms to detect online bullying behavior. As a result, this tutorial should appeal to researchers of several disciplines.
