Cover Story: This study focuses on enhancing a system that detects six types of cyberbullying tweets. By employing multi-classification algorithms on a cyberbullying dataset, our approach achieved a high accuracy, particularly with the TF-IDF (bigram) feature extraction. Our experiment achieved a high performance compared with that of previous experiments on the same dataset. Two ensemble machine learning methods, employing the N-gram with the TF-IDF feature extraction technique, demonstrated a superior performance in classification. Three popular multi-classification algorithms, which were Decision Trees, Random Forest, and XGBoost, were separately combined into two varied ensemble methods. These ensemble classifiers demonstrated a superior performance compared to that of traditional machine learning classifier models. View this paper
