Sentimental Analysis is one of the most trending research areas in the domain of Natural Language Processing. It is defined as the technique that helps in the analysis of people’s emotions, sentiments from written text. In this paper, various Machine Learning classification algorithms have been used for finding the polarity of the reviews. Specifically, comparative analysis of algorithms such as Stochastic Gradient Descent, Logistic Regression, Multinomial Naive Bayes, and Support Vector Machine has been done. Performance evaluation of these algorithms has been done on the basis of the accuracy achieved. The observed results show that the Stochastic Gradient Descent with Bag of Words model outperforms other algorithms and shows the highest accuracy of 88.76%.
