Detection of Hate Speech Spreaders with BERT

As social media grows, more and more users are disseminating hate speech through their posts. This often comes as a consequence of feeling a false security and anonymity in virtual environment. To stop hate speech spreaders, researchers started developing machine learning systems that automatically detect spreaders of hate speech based on the contents of their posts. This paper describes one such system which was trained on a corpus of English Twitter posts with a goal to predict if author of the given posts spreads hate speech or not. The features were crafted using fine-tuned BERT contextualized embeddings summed over the last 12 hidden states corresponding to the classification token, concatenated with the three binary variables called indicators. Binary variables were indicating whether hashtag, retweet or url were present in author's tweet posts, respectively. Feature vectors were then fed into a Logistic Regression classifier. Described model achieved 75% of accuracy score on the test set.
