Feature extraction or aspect extraction becomes important since one needs to know the qualities a product or a service have. In this research, we have analyzed hotel reviews by applying n-gram for feature. As the dataset is always noisy so basic preprocessing steps are applied before extraction. The features extracted are trained and tested by basic machine learning classifiers. Various machine learning algorithms like KNN, SVM, and random forest are used for the analysis of the performance. The evaluation measures are calculated at the end to validate the results. K-fold cross validation scheme is also applied on the dataset to improve the overall accuracy of the results.
