Machine learning algorithms developed by a team of Binghamton University researchers can differentiate bullies and aggressors on Twitter from normal users with 90% accuracy.

The researchers analyzed behavioral patterns of abusive Twitter users and how they differ from the activities of other Twitter users.

Binghamton's Jeremy Blackburn said the researchers then used crawlers, “programs that accumulate data from Twitter via a variety of mechanisms,” to gather the tweets and Twitter profiles of users, “as well as social network-related things, like who they follow and who follows them.”

The application of natural language processing and sentiment analysis on the tweets, along with social-network analyses of user connections, led to algorithms that automatically classified cyberbullying and cyberaggression.

Blackburn said, "In a nutshell, the algorithms 'learn' how to tell the difference between bullies and typical users by weighing certain features as they are shown more examples."
