Working reportArxivIdentify disinformationInfluence political discourse010Here we define a comprehensive annotation schema that goes beyond factuality and potential to do harm, extending to information that could be potentially useful, e.g., for government entities to notice or for social media to promote. Information about a possible cure for COVID-19 should get the attention of a fact-checker, and if proven false.

We designed the annotation instructions after careful analysis and discussion, followed by iterative refinement based
on observations from the pilot annotation.
we issue a call to arms to the research community and beyond to join the fight by supporting our crowd-sourcing annotation efforts. We plan to support the annotation platforms with fresh tweets. We further plan to release annotation platforms for other languages. Finally, we plan regular releases of the data obtained thanks to the crowdsourcing efforts.We collected frequent tweets (i.e., such with at least 500 retweets) about COVID-19 in March 2020, in both English and Arabic. We used twarc for crawling. To collect the tweets, we used the following keywords and hashtags for English.000000000100USAUSA

https://arxiv.org/pdf/2101.08210.pdf
Working reportArxivMedia consumptionElectoral campaigns100The wide spread of unfounded election fraud claims surrounding the U.S. 2020 election had resulted in undermining of trust in the election, culminating in violence inside the U.S. capitol. Under these circumstances, it is critical to understand the discussions surrounding these claims on Twitter, a major platform where the claims were disseminated. To this end, we collected and released the VoterFraud2020 dataset, a multi-modal dataset with 7.6M tweets and 25.6M retweets from 2.6M users related to voter fraud claims. To make this data immediately useful for a diverse set of research projects, we further enhance the data with cluster labels computed from the retweet graph, each user’s suspension status, and the perceptual hashes of tweeted images. The dataset also includes aggregate data for all external links and YouTube videos that appear in the tweets. Preliminary analyses of the data show that Twitter’s user suspension actions mostly affected a specific community of voter fraud claim promoters, and exposes the most common URLs, images and YouTube videos shared in the data.Our data collection process involved streaming Twitter data using a data-driven manually curated set of keywords and hashtags. We report on the span and volume of the collected data, as well as on analyses estimating its coverage.000000000101USAUSA

Some Facebook and Twitter posts denounced the Black Lives Matter group; other posts condemned the white nationalist movement. And some called for violence. To be clear, these were posts by fake personas created by Russian operatives. But their effects were real.

These data about engagement activities can be read by machine-learning algorithms, by platforms, and by humans. Manipulators are getting craftier at evading moderation efforts built upon these metadata categories by using platform features in unexpected ways. This report argues that social media metadata can be read as contextual evidence of manipulation in platforms. Reading metadata as a method to validate or dispute social media data can help us understand the craftiness of media manipulators.This report argues that reading metadata can help us more fully understand the craft of data work and the many roles of metadata in platforms. It provides avenues for identifying vulnerabilities and for pressuring platforms to do better. It points to some open questions for the future of what web archives of social media data can teach us and what their status will be in the future of disinformation studies.This report includes three case studies of social media metadata manipulation: politicians’ accounts on Instagram, official U.S. government Twitter accounts, and the Facebook ads purchased by the Russian-based Internet Research Agency010000000100USARUS

This leads us to conclude that fake news is targeted for audiences who are not likely to read beyond titles and is aimed at creating mental associations between entities and claims.First, we collected the news stories found in Buzzfeed’s 2016 article on fake election news on Facebook (Silverman 2016). Second, our own political news data set to strengthen our analysis and control for the limitations of the first data set. Our data set contains 75 stories from each of the three defined categories of news: real, fake, and satire. We collected this data by first gathering known real, fake, and satire new sources. Third, Burfoot and Baldwin data set Finally, we use a data set from (Burfoot and Baldwin 2009), which consists of 233 satire news stories and 4000 real news stories used in a classification task between these two types of news stories using lexical and semantic features.010010001000NANA

On a large sample of photo reshare cascades on Facebook, we find strong performance in predicting whether a cascade will continue to grow in the futureWe find that the relative growth of a cascade becomes more predictable as we observe more of its reshares, that temporal and structural features
are key predictors of cascade size, and that initially, breadth, rather than depth in a cascade is a better indicator of larger cascades. This prediction performance is robust in the sense that multiple distinct classes of features all achieve similar performance. We also discover that temporal features are predictive of a cascade’s eventual shape. Observing independent cascades of the same content, we find that while these cascades differ greatly in size, we are still able to predict which ends up the largest.
We sampled our anonymized dataset from photos uploaded to Facebook in June 2013 and observed any re- shares occurring within 28 days of initial upload.010000000000UNKUNK

We directly measured ideological homophily in friend networks and examined the extent to which heterogeneous friends could potentially expose individuals to cross-cutting content. We then quantified the extent to which individuals encounter comparatively more or less diverse content while interacting via Facebook’s algorithmically ranked News Feed and further studied users’ choices to click through to ideologically discordant content.Compared with algorithmic ranking, individuals’ choices played a stronger role in limiting exposure to cross-cutting content.Facebook010000000000USANA

We then examine the effect of individual reshares receiving a comment containing a link to a Snopes article on the evolution of the cascade. We find that receiving such a comment increases the likelihood that a reshare of a rumor will be deleted. Furthermore, large cascades are able to accumulate hundreds of Snopes comments while continuing to propagate. Finally, using a dataset of rumors copied and pasted from one status update to another, we show that rumors change over time and that different variants tend to dominate different bursts in popularityBy referencing known rumors from Snopes.com, a popular website documenting memes and urban legends, we track the propagation of thousands of rumors appearing on Facebook.010010000000NANA

Such racial asymmetries may exist alongside, or even instead of, ideological ones. Our computational analysis of 5.2 million tweets by the Russian government-funded “troll farm” known as the Internet Research Agency sheds light on these possibilities.We find stark differences in the numbers of unique accounts and tweets originating from ostensibly liberal, conservative, and Black left-leaning individuals. But diverging from prior empirical accounts, we find racial presentation—specifically, presenting as a Black activist—to be the most effective predictor of disinformation engagement by far. Importantly, these results could only be detected once we disaggregated Black-presenting accounts
from non-Black liberal accounts. In addition to its contributions to the study of ideological asymmetry in disinformation content and reception, this study also underscores the general relevance of race to disinformation studies.
On October 17, 2018, Twitter announced two data sets containing tweets posted by suspected IRA accounts. It posted one data set publicly but redacted the screen names, display names, and user IDs of all accounts that had accrued fewer than 5,000 followers at the time of account suspension. Of the 3,667 unique screen names present in this data set, only 167 (4.6%) were left unredacted. This data set was not suitable for the current study because we needed to know each author’s screen name and display name to categorize each tweet according to its author’s sockpuppet identity. Fortunately, Twitter also made an unredacted version of the data set available to researchers who fill out an application detailing how they plan on using it. We submitted this application and were granted access to Twitter’s official, unredacted IRA data set on March 29, 2019.010000000000USARUS

International Relations scholars have presented the online debate in terms of ‘information warfare’—that is, a number of strategic campaigns to win over local and global public opinion, largely orchestrated by the Kremlin and pro-western authorities. However, this way of describing the online debate reduces civil society to a mere target for manipulation. This article presents a different understanding of the debate. By examining the social media engagement generated by one of the conflict's most important events—the downing of the Malaysian Airlines Flight 17 (MH17) over Ukraine—we explore how competing claims about the cause of the plane crash are disseminated by the state, media and civil society.By analysing approximately 950,000 tweets, the article demonstrates how individual citizens are more than purveyors of government messages; they are the most active drivers of both disinformation and attempts to counter such information. These citizen curators actively shape competing narratives about why MH17 crashed and citizens, as a group, are four times more likely to be retweeted than any other type of user. Our findings challenge conceptualizations of a state-orchestrated information war over Ukraine, and point to the importance of citizen activity in the struggle over truths during international conflicts.950,000 tweets000000000100NANA

They establish connections between quantitative measures and the qualitative “story” of rumours, revealing differences among rumour types. In doing so, they construct multi-dimensional signatures (patterns of information flow over time and across other features) that describe a rumour’s temporal progression of rumour spreading behavior (within individual tweets), URL domain diversity, domains over time, lexical diversity, and geolocation information.
Each tweet within each rumour subset was coded into one of seven distinct categories related to the rumour behavior type: Misinformation (relaying rumour as fact). Speculation (develop or support growing rumour). Correction (clearly engate rumour). Question (actively challenges rumour). Hedge (passes along rumour but with doubt). Unrelated, or neutral/other (position unclear or neutral to researcher)
From their study, lexical diversity appears to correlate with different kinds of rumour spreading behavior. Speculation, for example, has higher lexical diversity than misinformation. They find that rumours with low lexical diversity spread without much substantial content variation, while rumours with high lexical diversity tend to be more “conversational” and appear to engage users in “collaborative sensemaking.”Twitter000000000100NANA

The study employs computational methods by analyzing over 8 million tweets and 1,350 news stories using topic modelingBuilding on the theory of (networked) gatekeeping and Herman and Chomsky’s propaganda model, the results show that SNS users follow networked gatekeeping practices by mostly associating fake news references to the alleged bias of MSM. On the other hand, MSM coverage tends to link fake news to SNS’s negative role in spreading misinformation. I argue here that there is a networked flak activity on Twitter which is defined as a collective negative response to MSM in order to discipline it, change its tone and editorial stance, or undermine the public’s trust in it.Two sets of large data were collected. The first set consisted of 8,116,792 tweets which referenced “#fakenews” was retrieved from Twitter for a period of over 7 months (from January to August 2017) using Boston University Twitter platform called Boston University-Twitter Collection and Analysis Toolkit000000000100USAUSA

Throughout its multi-year effort, the Internet Research Agency exploited divisions in our society by leveraging vulnerabilities in our information ecosystem. They exploited social unrest and human cognitive biases. The divisive propaganda Russia used to influence American thought and steer conversations for over three years wasn’t always objectively false. The content designed to reinforce in-group dynamics would likely have offended outsiders who saw it, but the vast majority wasn’t hate speech. Much of it wasn’t even particularly objectionable. But it was absolutely intended to reinforce tribalism, to polarize and divide, and to normalize points of view strategically advantageous to the Russian government on everything from social issues to political candidates. It was designed to exploit societal fractures, blur the lines between reality and fiction, erode our trust in media entities and the information environment, in government, in each other, and in democracy itself. This campaign pursued all of those
objectives with innovative skill, scope, and precision
The comprehensive dataset included:
~10.4 million tweets (of which ~6 million were original) across 3841 twitter accounts
~1100 YouTube videos across 17 account channels
~116,000 Instagram posts across 133 accounts
~61,500 unique Facebook posts across 81 Pages
There were ~77 million engagements on Facebook, ~187 million engagements on Instagram, and ~73 million engagements on original content on Twitter. Precise summary statistics are presented later in this report.

Despite various indirect efforts to shape cyberspace into an environment that is friendlier towards the government, we find that the Russian Internet remains generally open and free, although the current degree of Internet freedom is in no way a prediction of the future of this contested spaceTweets.

There are also several clusters centered on Russian regions, which is significant given the limited reach of the Internet in the regions outside of Moscow and St. Petersburg.
Russian Twitter features a great deal of activity generated by marketing campaigns and search engine optimization (SEO) initiatives, including both automated and coordinated human actors. After our initial mapping resulted in a network dominated by these ‘instrumental’ actors, we constructed a filter to limit their presence in the network and discover relationships among a wider variety of ‘organic’ actors.

Beginning with an initial set of over five million blogs, we used social network analysis to identify a highly active ‘Discussion Core’ of over 11,000. These were clustered according to long term patterns of citations within posts, and the resulting segmentation characterized through both automated and human content analysis.´- Unlike their counterparts in the U.S. and elsewhere, Russian bloggers prefer platforms that combine features typical of blogs with features of social network services (SNSs) like Facebook. Russian blogging is dominated by a handful of these "SNS hybrids." - While the larger Russian blogosphere is highly divided according to platform, there is a central Discussion Core that contains the majority of political and public affairs discourse. This core is comprised mainly, though not exclusively, of blogs on the LiveJournal platform. - The Discussion Core features four major groupings: — Politics and Public Affairs (including news-focused discussion, business and finance, social activists, and political movements) — Culture (including literature, cinema, high culture, and popular culture) — Regional (bloggers in Belarus, Ukraine, Armenia, Israel, etc.) — Instrumental (paid blogging and blogging for external incentives) - Political/public affairs bloggers cover a broad spectrum of attitudes and agendas and include many who discuss politics from an independent standpoint, as well as those affiliated with offline political and social movements, including strong ‘Democratic Opposition’ and 'Nationalist' clusters. - The Russian political blogosphere supports more cross-linking debate than others we have studied (including those of the U.S. and Iran), and appears less subject to the formation of self-referential 'echo chambers.' - Pro-government bloggers are not especially prominent and do not constitute their own cluster, but are mostly located in a part of the network featuring general discussion of Russian public affairs. However, there is a concentration of bloggers affiliated with pro-government youth groups among the Instrumental bloggers. - We find evidence of political and social mobilization, particularly in those clusters affiliated with offline political and social movements. - The online 'news diet' of Russian bloggers is more independent, international, and oppositional than that of Russian Internet users overall, and far more so than that of non-Internet users, who are more reliant upon state-controlled federal TV channels. - Popular political YouTube videos focus on corruption and abuse of power by elites, the government, and the police.Five millions of blogs000100000000NANA

Our method uses public activity to detect content that is part of IOs based on features derived solely from content.To assess how well content-based features distinguish these influence operations from random samples of general and political American users, we train and test classifiers on a monthly basis for each campaign across five prediction tasks. Content-based features perform well across period, country, platform, and prediction task. Industrialized production of influence campaign content leaves a distinctive signal in user-generated content that allows tracking of campaigns from month to month and across different accounts.We test this method on publicly available Twitter data on Chinese, Russian, and Venezuelan troll activity targeting the United States, as well as the Reddit dataset of Russian influence efforts.100000100100USACHN, RUS, VEN

We begin by discussing the economics of fake news. We sketch a model of media markets in which firms gather and sell signals of a true state of the world to consumers who benefit from inferring that state. We conceptualize fake news as distorted signals uncorrelated with the truth. Fake news arises in equilibrium because it is cheaper to provide than precise signals, because consumers cannot costlessly infer accuracy, and because consumers may enjoy partisan news. Fake news may generate utility for some consumers, but it also imposes private and social costs by making it more difficult for consumers to infer the true state of the world—for example, by making it more difficult for voters to infer which electoral candidate they prefer. We then present new data on the consumption of fake news prior to the election. We draw on web browsing data, a new 1,200-person post-election online survey, and a database of 156 election-related news stories that were categorized as false by leading fact-checking websites in the three months before the election.In the aftermath of the 2016 US presidential election, it was alleged that fake news might have been pivotal in the election of President Trump.

Of those people, 7,455 consented to participate in the study.

After completing the consent form, participants began the baseline survey. The baseline recorded email addresses, additional demographics, and a range of outcome variables. We also asked for each participant’s name, zip code, Twitter handle, and phone number (“in order for us to send you text messages during the study”), as well as the URL of their Facebook profile page (which we would use “solely to observe whether your Facebook account is active”).
we find that deactivating Facebook for the four weeks before the 2018 US midterm election (i) reduced online activity, while increasing offline activities such as watching TV alone and socializing with family and friends; (ii) reduced both factual news knowledge and political polarization; (iii) increased subjective well-being; and (iv) caused a large persistent reduction in post-experiment Facebook use. Deactivation reduced post-experiment valuations of Facebook, suggesting that traditional metrics may overstate consumer surplus.Between September 24th and October 3rd, we recruited participants using Facebook ads.

We also find that layperson cognitive reflection, political knowledge, and Democratic Party preference are positively related to agreement with fact-checker ratings; and that informing laypeople of each headline’s publisher leads to a small increase in agreement with fact-checkers.

In October 2018, Twitter retrospectively identified 2.9 million English-language tweets as covertly written by trolls from Russia's Internet Research Agency. Most active 2015-2017, these Russian trolls generally supported the Trump campaign (Senate Intelligence Committee, 2019) and researchers have traced how this content disseminated across Twitter. Here, we take a different tack and seek exogenous drivers of Russian troll activityWe find that trolling fell 35% on Russian holidays and to a lesser extent, when temperatures were cold in St. Petersburg. More recent trolls released by Twitter do not show any systematic relationship to holidays and temperature, although substantially fewer of these that have been made public to date. Our finding for the pre-2018 interference period may furnish a natural experiment for evaluating the causal effect of Russian trolling on indirectlyaffected outcomes and political behaviors — outcomes that are less traceable to troll content and potentially more important to policymakers than the direct dissemination activities previously studied. As a case in point, we describe suggestive evidence that Russian holidays impacted daily trading prices in 2016 election betting markets.Twitter dataset100000000100USARUS

Academic JournalInformation Processing and ManagementAmplify and create disinformationBots behavior010Here we use several public Twitter datasets to build a model that can predict whether or not an account is a bot account based on features extracted at the tweet or the account level. We then apply the model to Twitter's Russian Troll Tweets dataset. At the account level, we evaluate features related to how often Twitter accounts are tweeting, as previous research has shown that bots are very active at some account levels and very low at others.At the tweet level, we noticed that bot accounts tend to sound more formal or structured, whereas real user accounts tend to be more informal in that they contain more slang, slurs, cursing, and the like. We also noted that bots can be created for a range of different goals (e.g., marketing and politics) and that their behaviors vary based on those distinct goals. Ultimately, for high bot-prediction accuracy, models should consider and distinguish among the different goals for which bots are created.Twitter made the dataset public as part of an investigation of possible influence in the 2016 U.S. presidential election, as trolls attempted to influence a broad range of political debates (Shane & Mazzetti, 2918). The majority of the accounts are affiliated with the Internet Research Agency (IRA), a well-known Russian troll factory (Linvill, Boatwright, Grant & Warren, 2019). The majority of the others are from Iran and Venezuela (Romm, 2019). Only 33% of the English-language tweets contain a hashtag, but during the weeks leading up to the election, the troll dataset witnessed a significant increase in activity, with hundreds of thousands of tweets/retweets per week.100000000100MULRUS

Political Bias and Factualness in News Sharing across more than 100,000 Online Communities2021

Academic JournalProceedings of the International AAAI Conference on Web and Social Media010we conduct the largest study of news sharing on reddit to date, analyzing more than 550 million links spanning 4 years. We use non-partisan news source ratings from Media Bias/Fact Check to annotate links to news sources with their political bias and factualness.We find that, compared to left-leaning communities, right-leaning communities have 105% more variance in the political bias of their news sources, and more links to relatively-more biased sources, on average. We observe that reddit users’ voting and re-sharing behaviors generally decrease the visibility of extremely biased and low factual content, which receives 20% fewer upvotes and 30% fewer exposures from crossposts than more neutral or more factual content. This suggests that reddit is more resilient to low factual content than Twitter. We show that extremely biased and low factual content is very concentrated, with 99% of such content being shared in only 0.5% of communities, giving credence to the recent strategy of community-wide bans and quarantines.Reddit000000000100NANA

The Duke Reporter’s Lab identified nearly 100 active initiatives around the world in 2016. Building off of previous exploratory work by Amazeen, this research utilizes the framework of critical juncture theory to examine why fact-checking interventions are spreading globally at this point in time. Seen as a professional reform movement in the journalistic community, historical research on reform movements suggests several possible factors influencing the emergence of fact-checking such as a decline in journalism, easy access to technology for the masses, and socio-political strife.This study offers empirical support that fact-checking may be understood as a democracy-building tool that emerges where democratic institutions are perceived to be weak or are under threat and examines similarities between the growth of fact-checking interventions and previous consumer reform movements. As politics increasingly adopts strategies orchestrated by marketing and advertising consultants and agencies – exemplified in the Brexit referendum – political fact-checking may benefit from examining the path of consumer reform movements. For, before fact-checking can be effective at informing individuals, it must first establish itself within a structural environment.The presence and quantity of fact-checking organizations in countries around the world

Based on tweet data and connections to existing literature, we also demonstrate and discuss how mainstream media participate in rumoring, and note the role of a new breed of online media, “breaking news” accounts. This analysis offers a complementary perspective to existing studies that use surveys and interviews to characterize the role official accounts play in online rumoring.Our analysis examines the spread of rumors on Twitter during crisis events, primarily using a digital record of tweets related to a specific crisis event, collected in real- time using the Twitter Streaming API000000000100NANA

As part of their dataset, they collected 88 million public Twitter accounts, including screen names, tweet counts, followers/following counts, bios, and tweet content. During their analysis they detect a cryptocurrency scam botnet made up of 15,000 bots and identify tactics used by bots to appear credible while avoiding detection.The authors find that the Random Forest classifier proved to perform the best irrespective of the bot data used for training. The cryptocurrency botnet the researchers discovered could be described as a three-level hierarchy, which “consisted of the scam publishing bots, the hub accounts (if any) the bots were following, and the amplification bots that like each created tweet.” The cryptocurrency spam botnet spoofed legitimate cryptocurrency accounts before transitioning to spoofing celebrity and high-profile accounts. Minor edits were done to profile photos to evade detection. Spoofed cryptocurrency accounts made use of typos of the spoofed account’s name.Twitter000000000100NANA

Focusing on Twitter, we identify different patterns of information correcting behaviors and describe the actions, motivations, rationalizations and experiences of people who exhibited them. To do this, we analyze digital traces across two separate crisis events and interviews of fifteen individuals who generated some of those traces. Salient themes ensuing from this work help us describe: 1) different mechanisms of corrective action with respect to who gets corrected and how; 2) how responsibility is positioned for verifying and correcting information; and 3) how users’ imagined audience influences their corrective strategy.We synthesize these three components into a preliminary model and explore the role of imagined audiences—both who those audiences are and how they react to and interact with shared information—in shaping users’ decisions about whether and

how to correct rumors.
We focus on two false rumors from two crisis events. For both, we captured data using the Twitter Streaming API, executing forward-in-time collections based on keyword search terms selected and curated by our research team.
To better understand how Twitter users experience and reflect upon their rumoring and rumor-correcting behaviors, we conducted interviews with people who had participated in one of these rumors. To gain insight into different kinds of user behaviors, we attempted to interview individuals with different types of user behavior signatures. The signatures therefore served as a mechanism for enhancing the diversity of our interview sample

Expanding upon prior work, which has focused on rumor volume, we argue that considering the size of the exposed population is a vital component of understanding rumoring. Additionally, by combining all three approaches we discover subtle features of rumoring behavior that would have been missed by applying each approach in isolation. Using a case study of rumoring on Twitter during a hostage crisis in Sydney, Australia, we apply a mixed-methods framework to explore rumoring and its consequences through these three lenses, focusing on the added dimension

of exposure in particular.
Our approach demonstrates the importance of considering both rumor content and the people engaging with rumor content to arrive at a more holistic understanding of communication dynamics. These results have implications for emergency responders and official use of social media during crisis management.Our research team collected data during the Sydney Siege event for the explicit purpose of examining rumoring behavior during crisis events. Data collection utilized the Twitter Streaming API to track specific event-related terms and phrases including: sydneysiege, sydney, lindt, martinplace, and chocolate shop.

Rather than transgressing community norms, these accounts undertook efforts to connect to the cultural narratives, stereotypes, and political positions of their imagined audiences. Understanding this performative aspect of RU-IRA accounts is critical for understanding how the work of information operations not only includes activities of disseminating true or false information on social media, but also activities to reflect and shape the performances of other (not RU-affiliated) actors in these communities.""Our initial dataset consisted of 58.8M tweets that were posted and collected between December 31st 2015 and October 5th 2016.

This article analyzes the tweets of Hillary Clinton and Donald Trump in order to understand the communication strategies performed through this media.As of July 2018, President Trump has over 53 million followers and is one of the most followed account on the platform. It is just evidential that he is still a ‘tweeting’ President: from the 2016 Election to July 2018 he tweeted using his personal account around 4300 times, with an average of 7 tweets per day dealing with any topic of local and global relevance and with personal matters. It would be interesting to implement further research to evaluate the actual use of Twitter done by the US President in order to see if his attitude has remained the same as the one during the campaign or if differences are registered. Furthermore, Twitter’s unique data structure allows researchers to document the behavior of Twitter users and these results could be combined with ad-hoc surveys. Also experiments could be built and implemented to identify mechanisms of political uses of Twitter. This holds opportunities for future research on the potential of political Twitter messages to move their recipients into action.Tweets from Hillary Clinton and Donald Trump. Trump has been active on Twitter since March 2009 while Clinton since April 2013. At the end of November 2016, Trump had 16.3 million followers and Clinton had 11.4 million. Both candidates had a consistent growth of their followers’ in the last 6 months, respectively +73.4% for Trump and 59.3% for Clinton.000000000100USARUS

Since the inception of its English language TV network Russia Today in 2005 (now ‘RT’), the Russian government has broadened its operations to include Sputnik news websites in several languages and social media activities. Moscow, however, has also been accused of engaging in covert influence activities – behaviour historically referred to as ‘active measures’ in the Soviet KGB lexicon on political warfare. In this paper, we provide empirical evidence on how Russia since 2014 has moved towards a preference for active measures towards Sweden, a small country in a geopolitically important European region. We analyse the blurring of boundaries between public diplomacy and active measures; document phenomena such as forgeries, disinformation, military threats and agents of influence and define Russian foreign policy strategy.In summary, we conclude that the overarching goal of Russian policy towards Sweden and the wider Baltic Sea is to preserve the geostrategic status quo, which is identified with a security order minimising NATO presence in the region.Timeline of 26 forgeries and fake articles appearing in the Swedish information climate, 2015–July 2016.000010000000SWERUS

Political trolls, such as the ones linked to the Russian Internet Research Agency (IRA), have recently gained enormous attention for their ability to sway public opinion and even influence elections. Analysis of the online traces of trolls has shown different behavioral patterns, which target different slices of the population. However, this analysis is manual and labor-intensive, thus making it impractical as a first-response tool for newly-discovered troll farmsIn this paper, we show how to automate this analysis by using machine learning in a realistic setting. In particular, we show how to classify trolls according to their political role ---left, news feed, right--- by using features extracted from social media, i.e., Twitter, in two scenarios: (i) in a traditional supervised learning scenario, where labels for trolls are available, and (ii) in a distant supervision scenario, where labels for trolls are not available, and we rely on more-commonly-available labels for news outlets mentioned by the trolls. Technically, we leverage the community structure and the text of the messages in the online social network of trolls represented as a graph, from which we extract several types of learned representations, i.e.,~embeddings, for the trolls. Experiments on the "IRA Russian Troll" dataset show that our methodology improves over the state-of-the-art in the first scenario, while providing a compelling case for the second scenario, which has not been explored in the literature thus far.Twitter IRA data000000000100USARUS

We analyzed these short texts to evaluate how accurately Twitter represented the public opinion and real world events of significance related with the elections. We also analyzed the behavior of over a million distinct Twitter users to identify whether the platform was used to share original opinions and to interact with other users or whether few opinions were repeated over and over again with little inter-user dialogue. Finally, we wanted to assess the sentiment of tweets by both candidates and their impact on the election related discourse on Twitter.Some of our findings included the discovery that little original content was created by users and Twitter was primarily used for rebroadcasting already present opinions in the form of retweets with little communication between users. Also of significance was the finding that sentiment and topics expressed on Twitter can be a good proxy of public opinion and important election related events. Moreover, we found that Donald Trump offered a more optimistic and positive campaign message than Hillary Clinton and enjoyed better sentiment when mentioned in messages by Twitter users.Tweets000000000100USANA

For that, we analyze a dynamic model of opinion exchange in which individuals have imperfect information about the true state of the world and are partially bounded rational. Key to the analysis is the presence of internet bots: agents in the network that do not follow other agents and are seeded with a constant flow of biased information. We characterize how the flow of opinions evolves over time and evaluate the determinants of long-run disagreement among individuals in the network. To that end, we create a large set of heterogeneous random graphs and simulate a long information exchange process to quantify how the bots’ ability to spread fake news and the number and degree of centrality of agents susceptible to them affect misinformation and polarization in the long-run.We find that when bots at one extreme are relatively more e�cient at manipulating news (by targeting a small number of influential agents), the may be able to generate full misinformation in the long run, where beliefs are at one end of the political spectrum. There would be no polarization in that case, but at the expense of agents converging to the wrong value of θ, the parameter of interest. There are other situations where agents are on average correct, but have nonetheless very heterogeneous opinions. These cases would still be sub-optimal, as they may result in ine�cient gridlock and inactionWe fix the number of agents (or nodes) to n = 37 and the true state of the world at θ = 0.5. We also fix the initial distribution of beliefs so that the same mass of the total population lies in the middle point of each one of 7 groups. This rule basically distributes our agents evenly over the political spectrum [0, 1] such that each of the 7 groups contains exactly 7 of the total mass of agents. Moreover, we set the same variance for each agent world-view to be σ2 = 0.03. With both opinion and variance, we are able to compute the initial parameter vector (α0 , β0).Given these parameters, we draw and populate a large number M = 8, 248 of initial random networks g0 following the BAUER model described in Section (4.1). To generate heterogeneity, we consider values for m (number of meetings) in the set {1, .., 5}, the preferential attachment α in [0.5, 1.5], the attractiveness of nodes with no adjacent edges a ∈ {1, ...4}, and the probability p ∈ [0.01, 0.1]000000001000NANA

I investigated whether a sample of content items, which were posted to 408 German political Facebook pages in March 2017, could be retrospectively collected in June 2017, September 2017, and March 2018. 27% of the 132,068 test items were no longer accessible after 12 months. The deletion of complete pages was rare, but some prominent pages were not available retrospectively. Posts by the pages themselves were far more likely to be available compared to content, which was posted by private accounts to the pages. There were only small differences between the political parties, but there was substantial variation between

the distinct pages.

In this work, we leverage Twitter to study the discourse during the 2018 US midterm elections and analyze social bot activity and interactions with humans. We collected 2.6 million tweets for 42 days around the election day from nearly 1 million users. We use the collected tweets to answer three research questions: (i) Do social bots lean and behave according to a political ideology? (ii) Can we observe different strategies among liberal and conservative bots? (iii) How effective are bot strategies in engaging humans?We show that social bots can be accurately classified according to their political leaning and behave accordingly. Conservative bots share most of the topics of discussion with their human counterparts, while liberal bots show less overlap and a more inflammatory attitude. We studied bot interactions with humans and observed different strategies. Finally, we measured bots embeddedness in the social network and the extent of human engagement with each group of bots. Results show that conservative bots are more deeply embedded in the social network and more effective than liberal bots at exerting influence on humans.In this study, we use Twitter to investigate the partisan behavior
of malicious accounts during the 2018 US midterm elections. For
this purpose, we carried out a data collection from the month prior
(October 6, 2018) to two weeks after (November 19, 2018) the day

We discovered that a high number of accounts posting in Tagalog were suspended as part of Twitter's crackdown on interference operations after the 2016 US Presidential election. By combining text embedding and transfer learning, our framework can detect, with promising accuracy, malicious users posting in Tagalog without any prior knowledge or training on malicious content in that languageWe first learn an embedding model for each language, namely a high-resource language (English) and a low-resource one (Tagalog), independently. Then, we learn a mapping between the two latent spaces to transfer the detection model. We demonstrate that the proposed approach significantly outperforms state-of-the-art models, including BERT, and yields marked advantages in settings with very limited training data-the norm when dealing with detecting malicious activity in online platforms.we use Twitter as a test-bed to detect the activity of malicious accounts focusing on the 2016 US presidential election.

ACMIdentify disinformationFake news010We model rumor spread as a diffusion process on a network and suggest the use of an “anti-rumor” process similar to the rumor process. We study two natural models by which these anti-rumors may arise. The main metrics we study are the belief time, i.e., the duration for which a person believes the rumor to be true and point of decline, i.e., point after which anti-rumor process dominates the rumor process. We evaluate our methods by simulating rumor spread and anti-rumor spread on a data set derived from the social networking site Twitter and on a synthetic network generated according to the Watts and Strogatz modelWe find that the lifetime of a rumor increases if the delay in detecting it increases, and the relationship is at least linear. Further our findings show that coupling the detection and anti-rumor strategy by embedding agents in the network, we call them beacons, is an effective means of fighting the spread of rumor, even if these beacons do not share information.Twitter and on a synthetic network generated according to the Watts and Strogatz model.000000000100NANA

In particular, we present quantitative research on the presence and impact of these three “Ps” in online Twitter debates in two contexts: (i) the run up to the UK EU membership referendum (“Brexit”); and (ii) the information operations of Russia-backed online troll accounts. We first compare the impact of highly partisan versus mainstream media during the Brexit referendum, specifically comparing tweets by half a million “leave” and “remain” supporters. Next, online propaganda strategies are examined, specifically left- and right-wing troll accounts. Lastly, we study the impact of misleading claims made by the political leaders of the leave and remain campaigns. This is then compared to the impact of the Russia-backed partisan media and propaganda accounts during the referendumIn particular, just two of the many misleading claims made by politicians during the referendum were found to be cited in 4.6 times more tweets than the 7,103 tweets related to Russia Today and Sputnik and in 10.2 times more tweets than the 3,200 Brexit-related tweets by the Russian troll accountsAround 17.5 million tweets were collected up to and including 23 June 2016 (EU referendum day).

Here, we report results from a replication of the experiment conducted during the U.S. Presidential Election in 2012.In spite of the fact that get-out-the-vote messages typically yield smaller effects during high-stakes elections due to saturation of mobilization efforts from many sources, a significant increase in voting was again observed. Voting also increased significantly among the close friends of those who received the message to go to the polls, and the total effect on the friends was likely larger than the direct effect, suggesting that understanding social influence effects is potentially even more important than understanding the direct effects of messaging.

Academic JournalJournal of Contemporary European StudiesAmplify and create disinformationFake news010This study focused on the Portuguese 2019 elections to assess the reach of fake news compared to mainstream media news and to verify whether fake news had specific targets. We reviewed all posts (N=1197) from newspaper Facebook pages and fake news Facebook pages published during the campaign to verify their engagement. BuzzSumo assessed popularity by counting all posts’ shares, reactions and comments. Iramuteq software related the content of all published headlines by analyzing clusters of the most frequent words.Findings show that fake news had no greater reach than real news during the election campaign. However, fake news are more likely to be shared, while real news tend to get more reactions and more comments. In fake news headlines the terms associated with left-wing and government are the most common. The prime minister and the Socialist Party are associated with negative connotations. Results suggest that Portuguese fake news are related to rightwing extremism and publish hate content targeting corruption and leftist policies in general. Unlike other countries, anti-immigration discourse and fearmongering were not prominent contents.To evaluate the reach and effect of fake news pages on Facebook compared to newspapers, we considered for our analysis all posts, with political headlines, shared during this period by both websites. We used the BUZZSUMO database (buzzsumo.com), a platform that collects the engagement of news articles on social media, counting all the shares, reactions and comments from each post. In total we analyzed the engagement of 1197 posts (1020 from newspaper Facebook pages and 177 from fake news pages on Facebook). 010000000000NANA

Using text analysis based on time series.We found that while false rumors (misinformation) tend to come back multiple times after the initial publication, true rumors (facts) do not. Rumor resurgence continues, often accompanying textual changes, until the tension around the target dissolves. We observed that rumors resurface by partisan news websites that repackage the old rumor into news and, gain visibility by influential Twitter users who introduce such rumor into the Twittersphere. In this paper, we argue that media scholars should consider the mutability of diffusing information, temporal recurrence of such messages, and the mechanism by which these messages evolve over time.We traced the lifecycle of 17 popular political rumors that circulated on Twitter over 13 months during the 2012 U.S. presidential election.000000000100USANA

By conducting and analyzing selected keywords, seed accounts, and known links to content, the researchers were able to construct large network visualizations and found that on Twitter there are significant and persistent interactions between current and former military personnel and a broad network of Russia-focused accounts, conspiracy theory focused accounts, and European right-wing accounts. These interactions are often mediated by pro-Trump users and accounts that identify with far-right political movements in the US. Similar interactions are also found on Facebook.The authors’ definition of junk news includes various forms of propaganda and ideologically extreme, hyperpartisan, or conspiratorial political news and information. They note that much of this content is deliberately produced false reporting. The authors looked specifically at three “junk news” websites specializing in content on military affairs and national security issues for US military personnel and veterans: veteranstoday.com, veteransnewsnow.com, and southfront.org.Twitter and Facebook010000000100USANA

There are also several clusters centered on Russian regions, which is significant given the limited reach of the Internet in the regions outside of Moscow and St. Petersburg.

Russian Twitter features a great deal of activity generated by marketing campaigns and search engine optimization (SEO) initiatives, including both automated and coordinated human actors. After our initial mapping resulted in a network dominated by these ‘instrumental’ actors, we constructed a filter to limit their presence in the network and discover relationships among a wider variety of ‘organic’ actors.

Similar to the Russian blogosphere, the Twitter network includes a democratic opposition cluster associated with Gary Kasparov and the opposition Solidarity movement.1 In other respects the political clusters identified in Weblog and Twitter networks display interesting variation. Nationalists, who are very active in Russian blogs, do not appear to be organized in Russian Twitter (at least as of March 2011). Conversely, pro-Putin youth groups like the Young Guards and Nashi, and elected officials allied with them, have a distinct Twitter footprint.

While other clusters within Twitter often mirrored those in Weblogs, such as one cluster focused on major bloggers and online personalities, there were some Twitter clusters that had no clear Weblog analog. Most notably, there are two clusters of Twitter users affiliated with local government administrations in Tver and Ivanovo, representing active outreach to citizens by local government actors.

While the filtered version of the map successfully reduced the presence of SEO actors, it curiously eliminated a pro-government cluster as well. In the filtered map, whereas the number of political actors was greatly increased overall, a cluster in the original map that focused on President Medvedev’s economic modernization policy disappeared, along with related hashtags. One possibility is that, as we observed in the Russian blogosphere, some political initiatives have adopted the tactics and/or services of online marketers.

Working PaperComputational Propaganda Research ProjectAmplify and create disinformationPolarize society010This article examines which groups on Facebook and Twitter are most likely to consume and share “junk news,” which the authors define as misleading, deceptive, or incorrect information purporting to be real news about politics, economics, or culture. This includes various forms of extremist, sensationalist, conspiratorial, masked commentary, and fake news. They ultimately find that on Twitter, Trump supporters followed by conservatives are most likely to circulate junk news, while on Facebook, extreme hard right pages (different from Republican pages) share the widest range of junk news sources.There is little overlap in sources of news consumption between supporters of the Democratic Party and the Republican Party. They find that Democrats show high levels of engagement with mainstream media sources compared to Republicans and conservatives.
• On Twitter, the “Trump Support Group” shares 95% of the junk news sites on the watch list, and accounted for 55% of junk news traffic in the
sample. • On Facebook, the “Hard Conservative Group” shares 91% of the junk news sites on the watch list, and accounted for 58% of junk news traffic in the sample.
For this study, a seed of known propaganda websites across the political spectrum was used, drawing from a sample of 22,117,221 tweets collected during the US election, between November 1-11, 2016.

Using longitudinal data from the Twitter communication mentioning Members of Congress in the United States across a time span of over a year and relying on supervised machine learning methods and topic models, we offer new insights about the prevalence and dynamics of incivility toward legislators. We find that uncivil tweets represent consistently around 18% of all tweets mentioning legislators, but with spikes that correspond to controversial policy debates and political events. Although we find evidence of coordinated attacks, our analysis reveals that the use of uncivil language is common to a large number of users.To initiate our data collection, we relied on the list of Twitter accounts of Members of Congress elected to the 115th Congress (2017–2018) available in the unitedstates GitHub account.100000000100USAUSA

Research demonstrates a strong correspondence between the issues about which the public cares and the issues addressed by politicians, but conclusive evidence about who leads whom in setting the political agenda has yet to be uncovered.We answer this question with fine-grained temporal analyses of Twitter messages by legislators and the public during the 113th US Congress. After employing an unsupervised method that classifies tweets sent by legislators and citizens into topics, we use vector autoregression models to explore whose priorities more strongly predict the relationship between citizens and politicians.We find that legislators are more likely to follow, than to lead, discussion of public issues, results that hold even after controlling for the agenda-setting effects of the media. We also find, however, that legislators are more likely to be responsive to their supporters than to the general public.To test our hypotheses, we use tweets sent by members of the 113th House and Senate of the US Congress (2013–14).000000000100USAUSA

Consistent with this suggestion, two online studies with over 900 participants demonstrated that although delusion-prone individuals were no more likely to believe true news headlines, they displayed an increased belief in “fake news” headlines, which often feature implausible content. Mediation analyses suggest that analytic cognitive style may partially explain these individuals’ increased willingness to believe fake news.Exploratory analyses showed that dogmatic individuals and religious fundamentalists were also more likely to believe false (but not true) news, and that these relationships may be fully explained by analytic cognitive style. Our findings suggest that existing interventions that increase analytic and actively open-minded thinking might be leveraged to help reduce belief in fake news.Participants were recruited via Amazon’s Mechanical Turk (MTurk) in two waves (Study 1: n = 502, Study 2: n = 446; Demographics: SI Section S1).

A set of 38 city-specific inauthentic “newsfeeds” made up a large, underanalyzed part of its English-language output. We label 1,000 tweets from the IRA newsfeeds and a matched set of real news sources from those same cities with up to five labels indicating the tweet represents a world in unrest and, if so, of what sort. We train a natural language classifier to extend these labels to 268 k IRA tweets and 1.13 million control tweetsCompared to the controls, tweets from the IRA were 34% more likely to represent unrest, especially crime and identity danger, and this difference jumped to about twice as likely in the months immediately before the election. Agenda setting by media is well-known and well-studied, but this weaponization by a coordinated information operation is novel.First, we collected the output of the 38 locally oriented IRA newsfeed accounts from Twitter’s January 2019 update to their October 2018 release of the output they linked to the IRA (Roth, 2019), for the 13 months running from December 2015 to December 2016. We supplement these with 60,975 additional tweets produced from these same accounts during this period and downloaded from Social Studio but not included in the Twitter release000000000100USARUS

Reis, Philipe de Freitas Melo, Kiran Garimella, Fabrício BenevenutoDetecting Misinformation on WhatsApp without Breaking Encryption2020https://arxiv.org/abs/2006.02471Working PaperCornell UniversityIdentify disinformationInfluence political discourse010Due to the private encrypted nature of the messages it is hard to track the dissemination of misinformation at scale. In this work, we propose an approach for WhatsApp to counter misinformation that does not rely on content moderation. The idea is based on on-device checking, where WhatsApp can detect when a user shares multimedia content which have been previously labeled as misinformation by fact-checkers, without violating the privacy of the usersWe evaluate the potential of this strategy for combating misinformation using data collected from both fact-checking agencies and WhatsApp during recent elections in Brazil and India. Our results show that our approach has the potential to detect a considerable amount of images containing misinformation, reducing 40.7% and 82.2% of their shares in Brazil and India, respectively.To gather the data explored in this work we use available tools (Garimella and Tyson 2018) to get access to messages posted on public WhatsApp groups. selected over 400 and 4,200 groups from Brazil and India, respectively, dedicated to political discussions.000000000010BRA, INDBRA, IND

BenitoRecurrent Patterns of User Behavior in Different Electoral Campaigns: A Twitter Analysis of the Spanish General Elections of 2015 and 20162018https://www.hindawi.com/journals/complexity/2018/2413481/abs/Academic JournalComplexityAmplify and create disinformationManipulate opinions and democratic elections010We have retrieved and analyzed several millions of Twitter messages corresponding to the Spanish general elections held on the 20th of December 2015 and repeated on the 26th of June 2016. Te availability of data from two electoral campaigns that are very close in time allows us to compare collective behaviors of two analogous social systems with a similar context.By computing and analyzing the time series of daily activity, we have found a signifcant linear correlation between both elections. Additionally, we have revealed that the daily number of tweets, retweets, and mentions follow a power law with respect to the number of unique users that take part in the conversation. Furthermore, we have verifed that the topologies of the networks of mentions and retweets do not change from one election to the other, indicating that their underlying dynamics are robust in the face of a change in social context. Hence, in the light of our results, there are several recurrent collective behavioral patterns that exhibit similar and consistent properties in diferent electoral campaigns.Twitter messages retrieved with the Twitter Streaming API. We have chosen the following neutral keywords to flter the messages:

(i) Keywords for the 2015 election: 20D, 20D2015, #EleccionesGenerales2015

(ii) Keywords for the 2016 election: 26J, 26J2016, #EleccionesGenerales2016, #Elecciones26J

We have downloaded tweets during a period of more than two months before and afer each election. However, the core of our analysis has been focused on the 15 days of the ofcial electoral campaign, the refection day (day before the election), the election day, and the day afer. During that period of 18 days we have retrieved 1793145 tweets for the 2015 election and 1755438 for the 2016 election

We document that the majority of mainstream media coverage was negative for both candidates, but largely followed Donald Trump’s agenda: when reporting on Hillary Clinton, coverage primarily focused on the various scandals related to the Clinton Foundation and emails. When focused on Trump, major substantive issues, primarily immigration, were prominent. Indeed, immigration emerged as a central issue in the campaign and served as a defining issue for the Trump campaign.We find that the structure and composition of media on the right and left are quite different. The leading media on the right and left are rooted in different traditions and journalistic practices. On the conservative side, more attention was paid to pro-Trump, highly partisan media outlets. On the liberal side, by contrast, the center of gravity was made up largely of long-standing media organizations steeped in the traditions and practices of objective journalism.



Our data supports lines of research on polarization in American politics that focus on the asymmetric patterns between the left and the right, rather than studies that see polarization as a general historical phenomenon, driven by technology or other mechanisms that apply across the partisan divide.

Here we test that hypothesis using vector autoregression (VAR) comparing time series of election opinion polling during 2016 versus numbers of re-tweets or ‘likes’ of IRA tweets.changes in opinion poll numbers for one of the candidates were consistently preceded by corresponding changes in IRA re-tweet volume, at an optimum interval of one week before. In contrast, the opinion poll numbers did not correlate with future re-tweets or ‘likes’ of the IRA tweets. We find that the release of these tweets parallel significant political events of 2016 and that approximately every 25,000 additional IRA re-tweets predicted a one percent increase in election opinion polls for one candidate.tweets000000000100USARUS
