Big data as a tool for detecting (and punishing?) bullies

Big data as a tool for detecting (and punishing?) bullies: A group of researchers has developed a machine learning model that can detect tweets relating to bullying, and even identify bullies, victims and witnesses. How the model works and what it found In order to train their model, the researchers fed it two sets of tweets one they had determined to be about bullying activity and another that was not. Once the model had learned the language identifiers of tweets relating to bullying, it was time to turn it loose on real-world tweets. Not only did the system start identifying a great number of tweets, but it also discovered time patterns (they occur most frequently during the school week) and was able to pick out who played what role in the bullying.
