Abstract The exponential rise in social media users has led to the emergence of cyber bullying, which is bullying through electronic messaging. Social media gives bullies a rich environment in which to operate, leaving victims open to abuse. By identifying the bullies linguistic patterns, machine learning can be used to create a model that will automatically identify instances of cyber bullying. A supervised machine learning method for identifying and reporting cyber bullying is put forth in this study. Bullying behaviors are trained and recognized using a variety of classifiers. Cyber bullying has become a pervasive issue on social media platforms, with YouTube being one of the primary arenas where such behavior occurs. This project proposes a novel approach to detect instances of cyber bullying within YouTube comments using machine learning techniques. Evaluation of the proposed approach is conducted through rigorous testing on a diverse set of YouTube comments, encompassing different topics, languages, and cultural contexts. Performance metrics such as accuracy, precision, recall, and F1-score are used to assess the effectiveness of the detection system.

1. INTRODUCTION

   In recent years, the proliferation of social media platforms has facilitated unprecedented connectivity and communication among individuals worldwide. While these platforms offer myriad opportunities for interaction and collaboration, they also harbour darker phenomena, notably cyber bullying. Among the diverse array of social media platforms, YouTube stands out as a prominent arena where cyber bullying thrives, manifesting through abusive comments, derogatory remarks, and targeted harassment directed at users. Cyber bullying is when someone is harassed online using technology. Teens and young adults who use social networking sites are susceptible to attacks, and these platforms offer bullies a fertile medium. By using machine learning, we can identify language patterns that bullies and their victims employ, as well as establish criteria that automatically identify text that constitutes cyber bullying.

   Cyber bullying is the use of technology to harass, threaten, embarrass, or make targeted posts about an individual. Adults

   can engage in cyber bullying behaviors, which are more prevalent in young children and teenagers. Adults who commit such crimes are subject to harsh legal penalties, such as jail terms. Cyber bullying does not require physical force or face-to-face communication, in contrast to traditional forms of bullying. Cyber bullying is an act that can be carried out by anyone with an Internet-connected device.

   Bullies may come from intimate friends or strangers. With the prevalence of the Internet, social media has become a convenient and popular platform for people of all ages to communicate. However, social media has created several problems. Cyber bullying is a type of psychological abuse with a significant impact on society. It can be identified as a pattern of insulting messages that are posted repeatedly and that involve harsh or negative language. Cyber bullying on YouTube poses significant challenges for platform administrators, content creators, and users alike. Not only does it inflict psychological harm on victims, but it also undermines the overall user experience and tarnishes the reputation of the platform.

   Traditional methods of manual moderation struggle to cope with the sheer volume of user-generated content, necessitating the development of automated systems capable of detecting and mitigating instances of cyber bullying in real-time. Cyber bullying, a distressing manifestation of online aggression, has emerged as a prevalent and multifaceted issue in the digital age. Defined as the deliberate and repetitive use of digital communication platforms to intimidate, harass, or harm others, cyber bullying poses significant threats to the mental health, well- being, and safety of individuals, particularly adolescents and young adults who are frequent users of social media platforms like YouTube.

      Machine learning (ML) is a field of study in artificial intelligence concerned with the development and study of statistical algorithms that can learn from data and generalize to unseen data, and thus perform tasks without explicit instructions. Recently, artificial neural networks have been able to surpass many previous approaches in performance. Machine learning approaches have been applied to many fields including natural language processing, computer vision, speech recognition, email filtering, agriculture, and medicine.ML is known in its application across business

      problems under the name predictive analytics. Although not all machine learning is statistically based, computational statistics is an important source of the field's methods. As machine learning becomes more prevalent in everyday life, promoting digital literacy and education about AI and its societal impacts is essential to ensure informed decision- making and responsible use of technology by individuals, organizations, and policymakers.

   2. OBJECTIVE

      The core objective of machine learning is to develop algorithms and models that enable computers to learn patterns from data and make predictions or decisions without explicit programming. In other words, the primary goal of machine learning is to enable machines to learn from experience and improve their performance on a specific task over time. Machine learning algorithms aim to learn patterns, relationships, and structures within datasets. This learning process involves recognizing trends, making predictions, or identifying insights without being explicitly programmed for the task. The goal is not only to memorize the data seen during training but to generalize knowledge to new, unseen data. A well-trained machine learning model should perform accurately on previously unseen examples. By extracting relevant features and reducing dimensionality, it enhances computational efficiency and model performance while maintaining interpretability. The ability to recognize patterns, classify data, and predict future trends empowers decision- makers with actionable insights and foresight.
