Analisis Sentimen E-Wallet di Twitter Menggunakan Support Vector Machine dan Recursive Feature Elimination

Abstract

Grouping of positive or negative sentiments in text reviews is increasingly being done automatically for identification. The selection of features in the classification is a problem that is often not solved. Most of the feature selection related to sentiment classification techniques is insurmountable in terms of evaluating significant features that reduce classification performance. Good feature selection technique can improve sentiment classification performance in machine learning approach. First, two sets of customer review data are labeled with sentiment and then retrieved, processed for evaluation. Next, the supports vector machine (svm-rfe) method is created and tested on the dataset. Svm-rfe will be run to measure the importance of the feature by rating the feature iteratively. For sentiment classification, only the top features of the ranking feature sequence will be used. Finally, performance is measured using accuracy, precision, recall, and f1-score. The experimental results show promising performance with an accuracy rate of 81%. This level of reduction is significant in making optimal use of computing resources while maintaining the efficiency of classification performance

“…S.Sutresno (2023) menemukan bahwa SVM memiliki akurasi yang tinggi dibandingkan Naïve Bayes [11]. Penelitian yang dilakukan oleh Zhou, W., Chen (2020) menggunakan SVM-PSO dalam mengukur studi peringatan dini tentang risiko real estat di Beijing dan menemukan hasil akurasi sebesar 90% [12]. Kemudian penelitian yang dilakukan oleh Liu , W., Guo, dkk (2021) menemukan bahwa SVM-PSO memiliki kinerja yang lebih baik daripada model Adaboost dan ANN dalam menganalisis pola meteorologi untuk peramalan kualitas udara [13].…”

“…Data that has been weighted will begin to be classified with the Support Vector Machine (SVM) algorithm. The concept of this classification method is to find the best hyperplane by taking hyperplane measurements at the margin so that the maximum point is found [15]. The hyperplane is a one-dimensional subspace that smaller than the surrounding space and is used to separate data when there are three dimensions or more [16].…”
