Now-a-days there is no shortage of review forums, blogs and other social networking sites in this digital world. Many studies have been done in analyzing the sentiment of those reviews but the area of "college reviews" has not got much attention in the field of sentiment analysis. So, we have worked on analyzing college reviews and created a system called as College Review Analysis System which will be an online web based platform for automatically analyzing and predicting student review sentiment with the help of machine learning. This system analyses the sentiment of the review of every college in its database.Based on the sentiment, system will classify top college as per their review sentiment.This classification problem is tackled with the help of an algorithm called: "Random Forest".We compared the accuracy of Random Forest with other classifiers as well including "Naïve Bayes", "Decision Trees" and "Support Vector Machine" it turned out that Random Forest performed better in comparison with those classifiers.
