[pt] A PAUTA DA DESINFORMAÇÃO: FAKE NEWS E CATEGORIZAÇÕESDE PERTENCIMENTO NAS ELEIÇÕES PRESIDENCIAIS BRASILEIRAS DE 2018 / [en] THE TOPICS OF DISINFORMATION: FAKE NEWS AND MEMBERSHIP CATEGORIZATION ANALYSIS IN BRAZIL S 2018 PRESIDENTIAL ELECTIONS.

[pt] A disseminação de histórias falsas em aplicativos de mensagens e redes sociais da internet foi um dos elementos centrais da conversação civil no Brasil no período que antecedeu as eleições presidenciais brasileiras em 2018. A preocupação com a disseminação da desinformação – fenômeno que se compõe, entre outros elementos, por informações erradas, descontextualizadas, distorcidas ou falsificadas – se refletiu na quantidade de histórias falsas verificadas e desmentidas por agências independentes de checagens de fatos. No período de 20 dias entre as votações de primeiro e segundo turnos das eleições, as seis principais agências do país publicaram 228 verificações de histórias falsas disseminadas em redes sociais da internet ou aplicativos de troca mensagens, referentes a 132 diferentes pautas. A proposta desta pesquisa é identificar os temas destas histórias falsas e analisar as categorizações enunciadas em seus discursos, com a utilização da Análise de Categorização de Pertencimento (ACP), ferramenta teórico-metodológica de origem na Etnometodologia, aplicada aos textos das histórias falsas divulgados pelas agências. / [en] One of the main aspects of public debate in Brazil in the period that preceded the 2018 presidential elections was the dissemination of false stories via social media and messaging apps. Disinformation, misinformation and mal-information – phenomena that comprehends, among others, elements such as wrongful, out of context, distorted and fabricated information – were a major concern in the context of the election, which could be seen in the number of false stories debunked by independent fact-checkers. In the 20-day period between the two rounds of the presidential election, six fact-checking websites posted 228 verifications of false stories disseminated through social media and/or messaging apps, which covered about 132 different topics. This research aims to identify which were the topics of those false stories and analyze the categorizations enunciated in their discourses. In order to do so, the methodological perspective utilized was the Membership Categorization Analysis (MCP), affiliated with the tradition of Ethnomethodology, applied to the false stories discourses as quoted by the fact-checking websites.

Alternativa fakta eller faktiska alternativ : En kvalitativ studie om källkritik och falska nyheter

Blixt, Mikael January 2017 (has links)
Denna studie syftar till att söka inställningen till källkritik i dagens medielandskap hos ett antal intervjuade nyhetskonsumenter. I en värld med allt mer falska nyheter och större informationsmängd behöver vi se över hur vi ser på källkritik, vad det innebär att vara källkritisk och hos vem ansvaret för källkritiken ligger. För att söka dessa svar genomfördes en intervjustudie med semi-strukturerade intervjuer. Att källkritik är en komplex fråga framstod tydligt och den ökade mängden information gör den än mer komplex. Mängden information tillsammans med debatten om falska nyheter har bidragit till en ökad medvetenhet kring källkritik. Många intressanta frågor uppkommer som en följd av detta, bland annat hur en ska klara av att vara källkritisk.

Tradiční média a boj s tzv. fake news na příkladu BBC, ARD a Rádia Svobodná Evropa / Traditional media and its battle against fake news: the case of BBC, ARD and Radio Free Europe

Čáslavská, Veronika January 2019 (has links)
This thesis examines how traditional media could reinforce its position as a reliable source of information, overcoming the huge amount of misinformation in public space. First, the thesis analyzes the concept of fake news, examining different concepts of this expression across American and Anglo-Saxon environments. In the following chapters, the thesis presents a link between trust in media and the spread of fake news, outlines psychological factors that allow for fake news to be spread easily and highlights the role of media literacy. Next chapters list the specific ways in which traditional media can fight against fake news, for example through slow journalism or factual verification. That is how the thesis gets to the three analyzed fact-checking departments, which were established as a part of foreign traditional media: ARD Faktenfinder, BBC Reality Check and RFE / RL / VOA Polygraph.info. These departments were founded between 2015 and 2017 and perceive verification of information as an independent journalistic output. Using semi-structured interviews, the thesis examines how these departments work, how they define fake news, what are their future plans or whether they actively contribute to the development of media literacy. Comparative analysis has shown that none of the departments has...

The Daily Show: Journalism’s Jester

McCarthy, Mark R. 12 February 2009 (has links)
The social meaning of television news has been under transformation since the successes of cable news in the final years of the previous century. In their attempts to preserve viewership and to remain relevant, traditional broadcast news outlets increasingly emulate the conventions of cable news. Instead of retaining audiences, the result has been declining news content and a continued loss of viewers. Amid these industry transformations, the concept of “journalist” continues to undergo change. This evolution of the news allows for a decidedly unique response to news programming in The Daily Show With Jon Stewart. Though advertised as a half-hour comedy show, it has established itself as a consistent re-teller and producer of news, only possible in a postmodern era of journalism after objectivity. Amid the industry’s shift in priorities from objectivity and reporting to influencing, framing and re-telling the news, The Daily Show is considered as much an example of journalism as many of the shows currently in the news sphere. Although our society is currently saturated with information, this information often fails to penetrate the surface of the issues covered. Too much information is as paralytic as ignorance. Recently, attention has shifted towards a re-evaluation of television news into something that will both help the public find the information they are searching for and give them the tools to make sense of and utilize that information. This concept of journalism as tool is present in every episode of The Daily Show. The show encourages viewers to peel away the layers of mediation of traditional newscasts, to recognize substance and the lack thereof, and become active consumers of information rather than passive receptacles submersed in irrelevant information. The Daily Show proves that a news show can inform, entertain and teach audiences how to critically process television as an informational medium.

Last Night in Sweden : A Critical Discourse Analysis of the Image of Sweden in International Media

Linnander, Mathilda January 2018 (has links)
This is a study of how the image of Sweden is constructed in international media. Using the country as a swinging bat in debates on socialism and progressiveness is nothing new but has had an upswing during recent years as a result of the global rise of right-wing forces. With the help of Critical Discourse Analysis, four articles from the United States and the United Kingdom are analysed. These are then presented according to Fairclough’s three-layered model. With the help of previous research on Sweden in international media, fake news and nation branding, these findings are then explained and put into context.The study finds that the image of Sweden presented in media tends to follow the narrative of Good Sweden and Bad Sweden. On the one hand is the classic welfare state in the north, which takes care of its people and with high levels of trust between the actors. On the other hand is a country in ruins as a result of letting in too many immigrants. Both narratives rely heavily on stereotypes. The discussion tends to use Sweden as an example, when it is really about ideologies and values. Another result shown by the study is that fake news is a common trace in news about Sweden, not only in alternative media but also in the established elite media. This can be seen as a result of the hardening situation in the media business as well as the rise of right-wing forces.

Fake news : Kan korrekt information motverka lögner?

Eriksson, Joakim, Afanaseva, Anastasiya January 2018 (has links)
Sveriges regering och SÄPO har identifierat fake news som ett hot mot demokratin. I denna studie undersöker vi om fake news påverkar individer, trots att de vid samma tillfälle erhåller korrekt information inom ämnet. Detta gjordes genom en enkätundersökning på studenter vid Uppsala universitet. Vi fann att erhållandet av korrekt information inte är tillräckligt för att motverka effekten av att exponeras för falsk information. De studenter som fick läsa en mening med falsk information var 15 procentenheter mer sannolika att svara att de anser att staten lägger för mycket resurser på invandringen jämfört med kontrollgruppen. Resultatet tyder på att politiker, organisationer och privatpersoner kan dra nytta av att sprida fake news, att de kan göra så anonymt, och att faktagranskning ensamt inte kan stävja problemet med fake news. / The Swedish government and the Swedish Security Service have identified fake news as a threat to democracy. In this study, we investigate if fake news affect individuals, even though they receive correct information regarding the subject simultaneously. This was accomplished through handing out a survey to students at Uppsala University. We found that obtaining correct information is insufficient to counteract the effects of being exposed to fake news. The students who read a sentence with false information were 15 percentage points more likely to answer that they believe that the Swedish government allocates too much resources towards immigration compared to the control group. The result indicate that politicians, organizations and individuals can take advantage of spreading fake news, that they can do so anonymously, and that fact checking alone cannot solve the problem of fake news.

Detecting opinion spam and fake news using n-gram analysis and semantic similarity

Ahmed, Hadeer 14 November 2017 (has links)
In recent years, deceptive contents such as fake news and fake reviews, also known as opinion spams, have increasingly become a dangerous prospect, for online users. Fake reviews affect consumers and stores a like. Furthermore, the problem of fake news has gained attention in 2016, especially in the aftermath of the last US presidential election. Fake reviews and fake news are a closely related phenomenon as both consist of writing and spreading false information or beliefs. The opinion spam problem was formulated for the first time a few years ago, but it has quickly become a growing research area due to the abundance of user-generated content. It is now easy for anyone to either write fake reviews or write fake news on the web. The biggest challenge is the lack of an efficient way to tell the difference between a real review or a fake one; even humans are often unable to tell the difference. In this thesis, we have developed an n-gram model to detect automatically fake contents with a focus on fake reviews and fake news. We studied and compared two different features extraction techniques and six machine learning classification techniques. Furthermore, we investigated the impact of keystroke features on the accuracy of the n-gram model. We also applied semantic similarity metrics to detect near-duplicated content. Experimental evaluation of the proposed using existing public datasets and a newly introduced fake news dataset introduced indicate improved performances compared to state of the art. / Graduate
