Towards Automatic Fake News Detection in Digital Platforms: Properties, Limitations, and Applications

Abstract

Digital platforms, including social media systems and messaging applications, have become a place for campaigns of misinformation that affect the credibility of the entire news ecosystem. The emergence of fake news in these environments has quickly evolved into a worldwide phenomenon, where the lack of scalable fact-checking strategies is especially worrisome. In this context, this thesis aim at investigating practical approaches for the automatic detection of fake news disseminated in digital platforms. Particularly, we explore new datasets and features for fake news detection to assess the prediction performance of current supervised machine learning approaches. We also propose an unbiased framework for quantifying the informativeness of features for fake news detection, and present an explanation of factors contributing to model decisions considering data from different scenarios. Finally, we propose and implement a new mechanism that accounts for the potential occurrence of fake news within the data, significantly reducing the number of content pieces journalists and fact-checkers have to go through before finding a fake story.

Fake News Detection in Urdu using Deep Learning

“…This Model makes use of a BERT base design [1] that has been trained through using Common Crawl [4], Wikipedia [2]PMINDIA [5], as well as Dakshina [6] corpus for 17 different subcontinent languages.…”

“…Because it needs manually annotated news stories taken from the database by human experts, the first method is a complicated and time-consuming operation. The other three approaches make truth simpler and quicker since they concentrate on digitalization and the community for locating, evaluating, and analyzing critical knowledge [4].…”
