Abstract—This paper reports on the results of an analysis on user reviews of MOOCs. Using data collected from, a leading source for student-powered reviews MOOCs, we determine whether a given review is positive or negative. By applying the Naïve Bayes and Support Vector Machine (SVM) methods, we find that standard machine learning techniques definitely outperform human-produced baselines. We conclude by examining factors that make the sentiment analysis problem more challenging.
