Analyzing the Application of Machine Learning in Detecting Hate Speech: A Review

Abstract

Social media platforms offer avenues for fostering anonymous online connections, discussions on diverse topics like culture, politics, and community life. However, the proliferation of hate speech poses a pressing challenge for society, individuals, policymakers, and researchers alike, both on the continent and globally. Addressing this issue necessitates comprehensive studies to identify and combat hate speech effectively. This paper conducts a systematic review of literature in this domain, concentrating on methodologies such as word embedding, machine learning, deep learning, and cutting-edge technologies. Specifically focusing on the past six years of research, this review highlights gaps, challenges, and advancements in hate speech detection techniques. Additionally, it delves into limitations, algorithmic selection dilemmas, data collection complexities, cleaning challenges, and outlines future research pathways in this critical area. Keywords: Hate Speech Detection, Machine Learning, Social Media Platforms, Text Analysis, Algorithm Selection.
