Abstract

X (Twitter), with 237.8 million daily active users mostly aged 18 to 29, has become one of the largest and most influential communication platforms in the world. However, despite its potential as a tool for information sharing and interaction, X (Twitter) also presents major challenges in terms of online behavior. One of the main problems that has emerged is the rise of hate speech, which can damage the community atmosphere and create an unhealthy digital environment. This research classifies Indonesian hate speech tweets on X using Support Vector Machine (SVM) model and Particle Swarm Optimization (PSO) optimization algorithm to produce effective classification results from the text. The main objective of this research is to develop a system that can classify hate speech tweets with good and accurate accuracy, and compare the performance of the SVM model before and after being optimized with PSO. The dataset used in this research includes 1,000 hate speech tweets with 4 label classes, namely religious hate speech as much as 403 data, racial hate speech 318 data, physical hate speech 168 data, and gender hate speech 111 data. The processes in this research are data pre-processing, TF-IDF, and classification analysis with SVM and PSO. SVM accuracy value without PSO is 74.56%, SVM accuracy value optimized by PSO is 88.25%. This shows that parameter optimization using PSO can improve the performance of SVM models in text classification tasks.
