Bots & coordinated campaignsDetection methods Better Safe Than Sorry: an Adversarial Approach to improve Social Bot DetectionProposes GenBot, a novel genetic algorithm that synthesizes evolved versions of existing spambots by encoding behavioral timelines as "digital DNA" sequences and iteratively evolving them to resemble legitimate user behavior. Tests the evolved bots against three state-of-the-art detection systems and finds they largely evade detection… Cresci et al. · ACM Web Science Conference · 2019 Fact-checking & verificationPlatforms, policy & society Multi-Task Ordinal Regression for Jointly Predicting the Trustworthiness and the Leading Political Ideology of News MediaRather than predicting media bias and trustworthiness separately, this paper jointly models both as ordinal regression tasks using Copula Ordinal Regression. The intuition is that hyper-partisan outlets tend to be less trustworthy, while centrist outlets are more factual. Baly et al. · arXiv · 2019 Detection methodsDatasets & evaluation Beyond News Contents: The Role of Social Context for Fake News DetectionContent-only detection is insufficient because fake news is crafted to mimic real news. This paper argues that the tri-relationship among publishers, news pieces, and users forms rich social context for detection: partisan-biased publishers more likely publish fake news, and low-credibility users more likely share it. Shu et al. · ACM International Conference on Web Search… · 2019 Spread & networksPlatforms, policy & society Social Media for Political Campaigns: An Examination of Trump's and Clinton's Frame Building and Its Effect on Audience EngagementThis study analyzes how Trump and Clinton's 2016 campaigns framed messages on Twitter and Facebook, and how frame type affected audience engagement. Trump relied on conflict and negative emotional frames, while Clinton used morality and positive emotional frames.

Videos and images dominated message content (33% of all messages) and were heavily… Machado et al. · The Web Conference · 2019 Bots & coordinated campaignsPlatforms, policy & society Coordinating a Multi-Platform Disinformation Campaign: Internet Research Agency Activity on Three U.S. Social Media Platforms, 2015 to 2017This paper analyzes Russian Internet Research Agency activity across Facebook, Twitter, and Reddit from 2015–2017 using vector autoregression models on 3,126 Facebook ads, 1.9M tweets, and 12,603 Reddit posts. Key finding: Reddit activity influenced subsequent Twitter activity (a "trial balloon" effect), but the IRA's Twitter engagement… Lukito · Political Communication · 2019 Spread & networksPsychology & interventions Less than you think: Prevalence and predictors of fake news dissemination on FacebookFake news dissemination on Facebook during the 2016 election was a rare behavior (8.5% of users shared at least one article), with clear demographic stratification: conservatives shared more articles from fake news domains (pro-Trump), but the strongest and most robust predictor was age—users over 65 shared nearly seven times as many… Guess et al. · Science Advances · 2019 Spread & networksPlatforms, policy & society Fake news on Twitter during the 2016 U.S. presidential electionFake news consumption on Twitter during the 2016 election was extremely concentrated: only 1% of users saw 80% of exposures, and 0.1% shared 80% of fake news. Conservative-leaning, older, highly politically engaged users drove most consumption. Grinberg et al. · Science · 2019 Spread & networksPlatforms, policy & society How Many People Live in Political Bubbles on Social Media? Evidence From Linked Survey and Twitter DataEady et al. link survey data from 1,496 Americans to Twitter data from 642,345 accounts and ~1.2 billion tweets to measure political polarization in media consumption. Rather than finding evidence of extreme "filter bubbles" where most people consume ideologically homogeneous content, they find substantial overlap in the accounts… Eady et al. · SAGE Open · 2019 Psychology & interventionsPlatforms, policy & society Fake news game confers psychological resistance against online misinformationThis large-scale empirical study demonstrates that a free ~15-minute online browser game teaching six common misinformation production techniques (polarisation, emotional manipulation, conspiracy theories, trolling, discrediting opponents, impersonation) significantly reduces perceived reliability of misinformation across N=15,000… Roozenbeek & van der Linden · Palgrave Communications · 2019 Detection methodsDatasets & evaluation Comparative Studies of Detecting Abusive Language on TwitterConducts the first comprehensive benchmark of traditional machine learning and neural network models on the Hate and Abusive Speech on Twitter dataset (100K tweets). Bidirectional GRU networks with Latent Topic Clustering achieve the best performance (0.805 F1), outperforming traditional methods like logistic regression and SVM.

The work proposes frameworks for forecasting AI-enabled attacks, identifies specific threat scenarios including AI-generated disinformation and deepfakes, and recommends… Brundage et al. · arXiv · 2018 Spread & networksDatasets & evaluation The Web of False Information: Rumors, Fake News, Hoaxes, Clickbait, and Various Other ShenanigansComprehensive typology of the false information ecosystem on the Web, identifying eight types of false information (fabricated stories, propaganda, conspiracy theories, hoaxes, biased news, rumors, clickbait, satire), twelve actor categories (bots, criminal organizations, activists, governments, paid posters, journalists, useful idiots,… Zannettou et al. · arXiv · 2018 Bots & coordinated campaignsSpread & networks Who Let The Trolls Out? Towards Understanding State-Sponsored TrollsComparative analysis of 934 Russian and 770 Iranian state-sponsored trolls across Twitter and Reddit (10M posts) reveals distinct operational patterns: Russian trolls prioritized URL amplification (retweets, mentions) and pro-Trump messaging; Iranian trolls pursued regional and anti-Trump narratives motivated by real-world events. Both… Zannettou et al. · arXiv · 2018 Bots & coordinated campaignsPlatforms, policy & society Disinformation Warfare: Understanding State-Sponsored Trolls on Twitter and Their Influence on the WebLarge-scale empirical study of 2.7K Russian state-sponsored troll accounts and 27K tweets (Jan 2016–Sep 2017) reveals minimal direct Twitter influence but significant content amplification through RT news outlet. Trolls actively target political events, adopt multiple identities, concentrate geographically in USA/Germany/Eastern Europe,… Zannettou et al. · arXiv · 2018 Spread & networksDetection methods Studying Fake News via Network Analysis: Detection and MitigationThis chapter surveys network-based approaches to fake news detection and mitigation on social media, organizing fake news dissemination along three dimensions (content, social, temporal) and introduces methods exploiting network structure: homogeneous networks (friendship, diffusion, credibility) and heterogeneous networks (knowledge,… Shu et al. · Book chapter · 2018 Spread & networksPlatforms, policy & society Combating Fake News with Interpretable News Feed AlgorithmsThis position paper reviews fake news detection methods and argues that news feed algorithms are insufficiently transparent, enabling echo chambers and filter bubbles that amplify misinformation. The authors propose interpretable and explainable news feed algorithms as a solution, positioning transparency and user awareness as critical… Mohseni & Ragan · arXiv · 2018 Psychology & interventionsPlatforms, policy & society Hate Lingo: A Target-based Linguistic Analysis of Hate Speech in Social MediaThis paper presents the first large-scale linguistic and psycholinguistic analysis of hate speech categorized by its target: directed (personal attacks) versus generalized (targeting groups).
