Abstract

This study aims to identify user sentiment toward the Mobile JKN application by comparing lexicon-based labeling using the InSet sentiment lexicon with rating-based labeling derived from users' star ratings. The dataset consisted of 50,000 Google Play Store reviews, which were reduced to 34,317 valid reviews after preprocessing. Sentiment classification was performed using the Support Vector Machine (SVM) algorithm with CountVectorizer for feature extraction, while class imbalance was handled using the Synthetic Minority Over-sampling Technique (SMOTE). The lexicon-based approach achieved 99% accuracy, precision, recall, and F1-score. In contrast, the rating-based approach achieved 76% accuracy, 62% precision, 61% recall, and a macro-average F1-score of 60%, mainly due to lower performance in classifying neutral reviews. Labeling validity was evaluated using 300 manually annotated reviews created by two annotators as the ground truth. The results indicate that lexicon-based labeling is more effective than rating-based labeling for SVM-based sentiment classification. WordCloud visualization shows that negative sentiment is dominated by technical issues, whereas positive sentiment mainly reflects easier access to healthcare services.
