Cyberbullying is the use of technology to bully a person or group with the intent to hurt them socially, psychologically or even physically. Currently there are many young people being cyberbullied or involving in cyberbullying activities, and the cyberbullying offence has been defined as criminal activity by law. To avoid the severe results (e.g. spirit trauma, or be charged as criminal), cyberbullying detection emerged to real-time proactively prevent cyberbullying by generating early warning. Most studies on Cyberbullying detection focus on key-words search and sentiment filtering on textual contents. All of them neglects the online conversation's rich context information including texts, networks, time and demographics. In this talk, we will introduce a novel solution for applying AI approaches to detect cyberbullying by exploiting rich heterogeneous context information.
