Fake News Detection on Social Media: A Data Mining Perspective

TLDR
Wang et al. as discussed by the authors presented a comprehensive review of detecting fake news on social media, including fake news characterizations on psychology and social theories, existing algorithms from a data mining perspective, evaluation metrics and representative datasets.
Abstract
Social media for news consumption is a double-edged sword. On the one hand, its low cost, easy access, and rapid dissemination of information lead people to seek out and consume news from social media. On the other hand, it enables the wide spread of \fake news", i.e., low quality news with intentionally false information. The extensive spread of fake news has the potential for extremely negative impacts on individuals and society. Therefore, fake news detection on social media has recently become an emerging research that is attracting tremendous attention. Fake news detection on social media presents unique characteristics and challenges that make existing detection algorithms from traditional news media ine ective or not applicable. First, fake news is intentionally written to mislead readers to believe false information, which makes it difficult and nontrivial to detect based on news content; therefore, we need to include auxiliary information, such as user social engagements on social media, to help make a determination. Second, exploiting this auxiliary information is challenging in and of itself as users' social engagements with fake news produce data that is big, incomplete, unstructured, and noisy. Because the issue of fake news detection on social media is both challenging and relevant, we conducted this survey to further facilitate research on the problem. In this survey, we present a comprehensive review of detecting fake news on social media, including fake news characterizations on psychology and social theories, existing algorithms from a data mining perspective, evaluation metrics and representative datasets. We also discuss related research areas, open problems, and future research directions for fake news detection on social media.

Credibility Assessment of User Generated health information of the Bengali language in microblogging sites employing NLP techniques

TL;DR: In this paper, a novel dataset of Bangla health news, collected from Twitter, was created and fed to a fake news detection system, which employed state-of-the-art machine learning classifiers and neural network models to predict a label in a fixed category, thus achieving a maximum accuracy of 91% using CNN with fasttext embeddings.

Content-Based Fake News Detection With Machine and Deep Learning: a Systematic Review

TL;DR: A taxonomy of machine learning and deep learning models and features adopted in content-based fake news detection is proposed and their performance is compared over the analysed works as discussed by the authors , which is the first attempt at identifying, on average, the best-performing models and feature over multiple datasets/topics tested in all the reviewed works.

The Language of Fake News

TL;DR: The authors define fake news as news that is meant to deceive as opposed to inform and argue that there should be systematic differences between real and fake news that reflect this basic difference in communicative purpose.

Supervised Classification Methods for Fake News Identification

TL;DR: In this article, the authors present a comprehensive performance evaluation of eleven supervised algorithms on three datasets for fake news classification and compare them with the real and the false news, and show that fake news can propagate with an uncontrollable speed without verification and can cause severe damages.

Deep learning

TL;DR: Deep learning is making major advances in solving problems that have resisted the best attempts of the artificial intelligence community for many years, and will have many more successes in the near future because it requires very little engineering by hand and can easily take advantage of increases in the amount of available computation and data.

Prospect theory: an analysis of decision under risk

TL;DR: In this paper, the authors present a critique of expected utility theory as a descriptive model of decision making under risk, and develop an alternative model, called prospect theory, in which value is assigned to gains and losses rather than to final assets and in which probabilities are replaced by decision weights.

The social identity theory of intergroup behavior

TL;DR: A theory of intergroup conflict and some preliminary data relating to the theory is presented in this article. But the analysis is limited to the case where the salient dimensions of the intergroup differentiation are those involving scarce resources.

Advances in prospect theory: cumulative representation of uncertainty

TL;DR: Cumulative prospect theory as discussed by the authors applies to uncertain as well as to risky prospects with any number of outcomes, and it allows different weighting functions for gains and for losses, and two principles, diminishing sensitivity and loss aversion, are invoked to explain the characteristic curvature of the value function and the weighting function.
