Abstract

User reviews on e-commerce are one of the important elements in e-commerce. User reviews can help potential buyers make decisions based on the experiences and opinions of other people, for example women's e-commerce reviews. In providing positive, neutral or negative sentiment reviews, understanding customer perceptions is challenging. Classifying sentiment reviews will solve this problem, several classification techniques have been carried out, but there is still room for development in the use of simple machine learning techniques and sampling to overcome data class imbalance. Classification techniques used in this paper include Naive Bayes, SVM, and KNN. These algorithms will be compared to determine the most accurate model. Several preprocessing techniques are also carried out such to balance the dataset using ROS and SMOTE. It was obtained that the SVM method with ROS had the highest accuracy of around 0.94 for accuracy value, 0.93 for precision value, 0.94 for recall, and 0.92 for F1-score value. This research shows that the use of sampling techniques such as ROS and SMOTE can be effective in balancing imbalanced datasets, thereby improving model classification performance. These findings can be a reference for developing more efficient and accurate sentiment classification models, especially in the case of imbalanced data.

Abstract

Hak asasi manusia atau HAM merupakan suatu hal yang paling dasar dari seseorang manusia. Di dalam Undang-undang Dasar Negara Republik Indonesia Tahun 1945 yang menyatakan bahwa Negara bertanggung jawab atas perlindungan Hak asasi manusia. Di dalam pasal 28I ayat (4) menyatakan bahwa perlindungan, pemajuan, penegakan, dan pemenuhan hak asasi manusia adalah tanggung jawab negara, terutama pemerintah. Meskipun pemerintah telah memberikan perlindungan hak asasi manusia dari pasal tersebut, masih ada beberapa peristiwa yang melenceng dari hak asasi manusia itu sendiri. Inilah seberapa pentingnya Pendidikan kewarganegaraan dalam mengajarkan tentang hak asasi manusia kepada kita semua. Agar nantinya hak asasi manusia dapat terjalankan sesuai dengan tujuannya.
