Abstract

Indonesia is one of the largest social media users in the world, with Twitter/X being a particularly popular platform, ranking sixth in the world for the number of users. However, this massive use of social media also presents significant challenges related to hate speech. Hate speech on social media is a concerning issue because it can spread quickly and widely influence audiences, potentially leading to real-world violence. Despite this, there is still a lack of research aimed at developing better models for the Indonesian language.
Naive Bayes (NB) is one of the traditional models commonly used for text detection. NB is a probabilistic model based on the assumption of feature independence. However, in text data classification, the relationships between features are important. The Artificial Neural Network (ANN) model can be used to overcome the weaknesses of the NB model. ANN can capture and model non-linear relationships between features in the data. By using ANN for feature extraction, feature representation becomes more refined, allowing NB to work with more informative and relevant features, thereby enhancing the performance of the NB model.
Implementing ANN feature extraction on NB (ANN-NB) in this study has proven to improve the NB model's performance in both classical scenarios of splitting the dataset into 70:30 and in data stream mining scenarios. The highest accuracy achieved was 97.6% which measured by confusion matrix.
