Meanwhile, the algorithm used is Nave Bayes Classifier (NBC), Support Vector Machine (SVM), also SMOTE Upsampling for the k-Nearest Neighbor (k-NN) algorithm. The classification result shows 702 negative feedback reviews and 2531 positive feedback reviews. The evaluation of algorithm performance shows the accuracy of SVM is 78,30% and NBC is 78,29% compared with k-NN with 85,24% accuracy, using SMOTE Upsampling with a class precision description of 100% prediction negative (1784 true Neg & 0 true Pos) and 77,21% prediction positive (747 true Neg & 2531 true Pos). The class recall description also shows 70,49% true Negative (1784 pred Neg & 747 pred Pos) and 100% true Positive (0 pred Neg & 2531 pred Pos).
