Controversy Detection on Twitter with Dynamics and Content-Based Features
摘要
On social platforms like Twitter (now, X), users frequently share opinions on daily matters, sometimes aggressively due to online anonymity. These interactions may lead to “controversies" where differing views on a topic arise. This paper builds on an existing controversy detection framework that relies on interaction dynamics within trending topics. We enhance this framework by incorporating content-based features, such as the distribution of URLs, hashtags, and mentions, to assess whether these additions improve model performance. To evaluate the impact of both interaction dynamics and content-based features, we trained three classifiers-a decision tree, an SVM, and a random forest-using two distinct feature spaces. Models trained solely with interaction dynamics served as the baseline, while models with the extended feature space demonstrated the effect of content-based features on performance. Our experiments reveal that integrating content-based features significantly enhances model performance across nearly all metrics on the tested tweet datasets, outperforming baseline models and demonstrating the value of our hybrid approach.
