Abstract

The M2U ID app is the primary digital banking platform of PT Bank Maybank Indonesia Tbk, serving as a crucial tool for supporting customers’ online transactions. The objective of this study is to analyze user review sentiment on the Google Play Store by comparing the performance of the Random Forest and Support Vector Machine (SVM) algorithms. A total of 16,270 review data points were collected via web scraping and processed through preprocessing stages and feature extraction using N-Gram-based TF-IDF with Chi-Square feature selection using the SelectKBest approach. Given the significant imbalance in data distribution, this study applied class weighting techniques as well as hyperparameter optimization using Grid Search and 5-Fold Cross-Validation. Testing on 3,254 test data points indicated that SVM performed more optimally with an accuracy rate of 82% and an F1-Macro score of 0.6344, compared to Random Forest, which yielded an accuracy of 73% and an F1-Macro score of 0.5832. The main contribution of this study is an in-depth analysis of classification errors in the minority (neutral) class, which has a low F1-score (0.16–0.17). The results of the error analysis show that the model’s limitations are caused by the ambiguity of technical features and the overlap of vocabulary in reviews with minimal emotional content.

Abstract

The rapid advancement of digital technology has spurred the emergence of online philanthropy platforms like Kitabisa, which collect a large volume of user reviews. Reviews on the Google Play Store reflect both satisfaction levels and service issues, but their unstructured nature makes manual analysis difficult. This study evaluates user sentiment on the Kitabisa platform by comparing the Support Vector Machine (SVM) and Naive Bayes models. A dataset of 11,887 reviews was processed through preprocessing and word weighting using the TF-IDF approach. The evaluation results show that the Support Vector Machine outperformed Naive Bayes with an accuracy of 84.05% and an F1-score of 0.93, while Naive Bayes achieved an accuracy of 81.73% and an F1-score of 0.92. Theoretically, this study reinforces the literature regarding the superiority of Support Vector Machines for unstructured text data. Additionally, the results of this research produce an automated evaluation framework that can be used by application developers as a basis for improving service quality in accordance with user perceptions accurately.

Abstract

Credit card transaction fraud detection is commonly treated as a binary classification problem, whereas operational risk management requires more detailed risk-level information to support investigation prioritization. This study proposes a hybrid machine learning framework for transaction risk stratification. In the first stage, the K-Means algorithm was applied to the training set to discover latent risk structures and generate cluster-based risk labels. Subsequently, a Random Forest model was trained to predict risk levels for new transaction data. To maintain evaluation objectivity, the dataset was divided into training, validation, and testing sets, and data leakage prevention mechanisms were implemented. The testing results show that the model was able to consistently classify two levels of risk with stable precision, recall, and F1-score values. In the binary fraud detection scenario, the model achieved an accuracy of 0.8831. These findings indicate that separating latent risk exploration from predictive classification can produce a more informative risk representation compared to conventional binary approaches. However, this study is still limited to a single public dataset and one classification model. Therefore, the generalizability and potential performance improvements of the model still need to be evaluated by experimenting with other algorithms.
