Abstract: Abstract The existence of fake news is a problem challenging today’s social media enabled world. Fake news can be classified using different methods. Predicting and detecting fake news has proven to be a challenge even for machine learning algorithms. This research attempts to investigate nine such machine learning algorithms to understand their performance with Credibility-Based Fake News Detection. This study uses a standard dataset with features relating to the credibility of news publishers. These features are analysed using each of these algorithms. The results of these experiments are analysed using four evaluation methodologies, namely the Receiver Operating Characteristic (ROC) curve, the precision-recall curve, the Lift curve, and numerical metrics. The analysis of these experiments and results reveals varying performance with the use of each of the nine methods. Based upon our selected dataset, the Two-Class Boosted Decision Tree has proven to be best suited for the purpose of Credibility-Based Fake News Detection. Based upon this conclusion, the main contribution of this paper, a deep analysis of the excellent performance of the Two-Class Boosted Decision Tree for Credibility-Based Fake News Detection is finally presented.
