Abstract
This paper presents a cyberbullying detection system designed to identify and mitigate
instances of cyberbullying on social media platforms using machine learning algorithms. By
leveraging natural language processing and sentiment analysis, our system classifies posts
as harmful or benign, aiding platforms in real-time intervention. The proposed approach
aims to enhance online safety and support mental well-being among users.

I. Introduction
A Cyberbullying Detection System for social media is designed to identify and mitigate
instances of online harassment. It employs machine learning algorithms and NLP
techniques to analyze user-generated content for harmful behavior, promoting a safer
online environment.
II. Literature Review
Several studies have proposed various machine learning approaches for detecting
cyberbullying. Techniques such as Support Vector Machines, Random Forests, and Neural
Networks have shown promising results in identifying harmful content.
III. Research Gaps
Existing cyberbullying detection systems face challenges such as language diversity,
evolving slang, privacy concerns, and real-time detection delays, which limit their
effectiveness.
IV. Proposed System
Our system collects data from social media, preprocesses text, extracts features using TF-
IDF and word embeddings, and classifies content using a hybrid machine learning approach.
Sentiment analysis further enhances detection accuracy.
V. Experimental Setup
We use datasets from platforms like Twitter and Facebook, applying machine learning
models such as SVM and BERT. The system is evaluated using accuracy, precision, recall,
and F1-score.
VI. Conclusion
Our system effectively detects cyberbullying instances with high accuracy. Future work will
focus on improving multilingual support and real-time monitoring capabilities.
