Fake News Detection using Machine Learning

Abstract

In recent years, the proliferation of fake news has precipitated numerous social and political quandaries. As the predominant source of information shifts towards digital platforms, discerning accountability for disseminated opinions becomes increasingly challenging, hindering authentication of received information. Given the pervasive nature of ecological and societal dilemmas, the role of machine learning in combating fake messages on social media is paramount. The virality of messages, whether genuine or fabricated, underscores the necessity for an automated, resilient, dependable, and efficient detection mechanism amidst multifarious challenges. This review delves into the contemporary landscape of fake news detection mechanisms within social media. By examining the contextual backdrop of fake news and its ramifications on users, we explore various methodological approaches categorized as content-based, social context-based, and hybrid-based methods. Culminating with an elucidation of four pivotal research challenges, this paper aims to steer future endeavors towards advancing the field.

Introduction

I. INTRODUCTION

The enormous size of the internet enables the generation and dissemination of an unprecedented volume of data and knowledge, surpassing what one can initially obtain. Consequently, false news or rumors can easily proliferate across online platforms, enabling users to unwittingly propagate them, leading to a cascade of deliberate falsehoods. Over the recent years, researchers have been delving into the dynamics of information dissemination and its impact on social media, with a particular focus on themes such as Opinion mining, user connections, sentiment analysis, and hate distribution are pivotal in combating the proliferation of misinformation, particularly in the context of politically significant events such as elections. Researchers have conducted a comprehensive analysis of divergent perspectives on fake news, drawing from a scientific review of literature spanning the past decade. Their focus lies in evaluating technical training methodologies aimed at detecting fake news, emphasizing the distinctive features of various techniques and cognitive frameworks for discerning falsehoods. However, the inherent lack of content control in social networks has facilitated the emergence of nefarious activities, including the dissemination of hate speech and fake news. Consequently, there has been a surge in interest among security researchers towards scrutinizing online platforms such as Online Social Networks (OSNs), blogs, and forums. A multitude of tasks have arisen, ranging from bot detection in OSNs to the identification of hate speech. Several studies have delved into the propagation of fake news on platforms like Twitter during significant events such as the 2016 U.S. presidential election, revealing alarming levels of exposure and dissemination of falsehoods. To mitigate the spread of fake news, preemptive identification of users prone to believing such misinformation is crucial. These findings underscore the imperative of devising precise techniques to identify and counteract the dissemination of fake news effectively spreading. Traditional techniques for identifying fake news often rely on conventional methods of feature extraction, such as Bag of Words and TF-IDF. However, contemporary approaches also explore innovative methods like automatic fact-checkers and detectors.

II. L ITERATURE REVIEW
