Att hantera desinformation på sociala medier : En normativ studie utifrån den deliberativa demokratiteorin / Handling disinformation on social media : A normative study based on the deliberative democratic theory

Gustafsson, Mikaela January 2017 (has links)
The dissemination of disinformation is unwanted, but on the rise in Sweden, often via social media. Since the deliberative democratic ideal stresses the importance of good democratic dialogues, this study therefore aims at giving an answer to the question of how this theory claims disinformation in the comment section on social media should be handled. Via a normative given-that analysis the question is analysed from a normative perspective, based on what is required for a conversation to be deliberative, and problematized from a practical perspective. The analysis shows that disinformation disturbs the conversation, and thereby normatively should be erased. Meanwhile, the problematization shows that practically deleting a comment could go against the ideal, since only comments which are intended to misinform should be deleted, and the question of whether such an intent exists can be hard to determine. To solve the feasibility problem and thereby give the research question a clear answer, a theory development of the deliberative theory is being made. The essay concludes that following the new way of seeing the deliberative ideal, the comments which are suspected to contain disinformation should be left in the comment section, but ideally thoroughly via a deliberative conversation be questioned.

Renseignement et contre-espionnage entre Dublin, Londres et Edimbourg de 1845 à 1945 / Intelligence and counter-espionage between Dublin, London and Edinburgh from 1845 to 1945

Berthillot, Émilie 19 September 2014 (has links)
Cette thèse démontre dans quelles mesures le recours aux agents secrets permet à Londres de dissimuler ses faiblesses notamment dans ses conflits avec l’Ecosse et l’Irlande. En effet, les mouvements dissidents écossais et irlandais mettent en péril le fondement même du Royaume-Uni en remettant en cause leurs actes d’Union signés avec Londres. Le pouvoir central se base donc sur l’efficacité et la puissance de ses agents secrets pour soutenir ses forces armées. Dès le XVème siècle, les monarques anglais, avides de subterfuges, envoient beaucoup d’espions en France. Par la suite, Londres instaure des forces de police à Dublin, Edimbourg et Londres, qui lui rendent compte des moindres complots grâce à l’infiltration de détectives dans des organisations rebelles comme le Clan na Gael, un fonctionnement qui lui permet de mater les rébellions malgré l'alliance irlando-écossaise. Toutefois, Michael Collins amène Londres à négocier grâce à la guerre d’espions (1919-1921) dans laquelle il cible les agents britanniques en imitant leurs méthodes et en développant un réseau de contre-espionnage performant. A l’aube de la Seconde Guerre mondiale, la neutralité de l’Eire proclamée par Éamon De Valera précipite Londres dans un jeu très dangereux de coopération, d’espionnage et de manipulation politique de l’Irlande dans lequel les relations diplomatiques jouent un rôle clé, mais où la collaboration irlandaise auprès des Alliées s’avère précieuse. Cette thèse essaie de démontrer que les conflits opposant Dublin et Edimbourg au pouvoir central poussent ce dernier à s’affirmer, à développer et professionnaliser ses services de renseignement qui, de fait, gagnent une renommée mondiale. / This dissertation illustrates to what extent the use of secret agents allows London to conceal her weaknesses more specifically in her conflicts with Scotland and Ireland. In fact, Scottish and Irish rebel movements question the very founding of the United Kingdom when they want to repel their acts of Union with London. The central power relies on the effectiveness and power of British secret agents to help the army. Since the 15th century, English kings, fond of spying games and manipulation, have sent spies to France. In the 19th century, London installs police forces in Dublin, Edinburgh and London which warn the British government of every single plot raising owing to many detectives infiltrated in rebel organizations like Clan na Gael. This operating is very efficient and permits the central government to stifle the rebellions in spite of the alliance between Ireland and Scotland. Yet, Michael Collins forces the British government to negotiate thanks to the intelligence war (1919-1921) in which his squads target the British agents in Dublin using their methods and developing a large very efficient network of spies and informants. At the beginning of the Second World War, Éamon De Valera’s declaration of Eire’s neutrality urges London to play a very dangerous game of cooperation, espionage and political manipulation with Ireland in which diplomatic relations play a key role and the Irish collaboration with the Allies turns out to be very precious. This thesis tries to demonstrate that when fighting against Scottish and Irish rebels, London must reassert its power by developing and professionalizing its intelligence services which end up with a worldwide reputation.

Manipulace, dezinformace a chyby v televizním zpravodajství / Manipulation, disinformation and faults in television news

Ziková, Jitka January 2010 (has links)
The thesis considers with balance and objectivity of the main news program of Česká televize. It tries to unfold inaccurate coverages, being transmitted in Události from september 2009 until december 2009. Inadequacies are further described and analysed in detail. Based on personal judgement, there is a possible reason and inflictor stated. The objective of this thesis is to point out Inadequacies in main news service of statutory television from view of objectivity, balance, correctness and other faults. Further provides aspects, which are the most frequent purpose of making faults. Thesis supplements monthly reports of Czech info company, which judges balance of news service only in constrained scale. The results of analysis provides valueable ratings of Události not only for television management, but for redactors themselves and other members of news team. The thesis doesn't lack even consideration about possibility of minimalisation the mentioned inadequacies. The source of information and data are articles, documents from Česká televize database, news service online archiv and experience from working in news room ČT. First part of thesis is concentrated on theoretical base. Serves to understand the whole problematics and as starting point for rest of the thesis. Even contains practical examples of manipulation and disinformation from the past and present. Second part describes the way of investigation of Česká televize news service and defines criteria of ratings. Third part of the thesis summarises results of the analysis, judges frequency and importance of inadequacies in news service and summarises their characteristics and elimination possibility. Conclusion summarises knowledge of the thesis, their comments, and enrichment from ČT news room experience.

Understanding Disinformation: Learning with Weak Social Supervision

January 2020 (has links)
abstract: Social media has become an important means of user-centered information sharing and communications in a gamut of domains, including news consumption, entertainment, marketing, public relations, and many more. The low cost, easy access, and rapid dissemination of information on social media draws a large audience but also exacerbate the wide propagation of disinformation including fake news, i.e., news with intentionally false information. Disinformation on social media is growing fast in volume and can have detrimental societal effects. Despite the importance of this problem, our understanding of disinformation in social media is still limited. Recent advancements of computational approaches on detecting disinformation and fake news have shown some early promising results. Novel challenges are still abundant due to its complexity, diversity, dynamics, multi-modality, and costs of fact-checking or annotation. Social media data opens the door to interdisciplinary research and allows one to collectively study large-scale human behaviors otherwise impossible. For example, user engagements over information such as news articles, including posting about, commenting on, or recommending the news on social media, contain abundant rich information. Since social media data is big, incomplete, noisy, unstructured, with abundant social relations, solely relying on user engagements can be sensitive to noisy user feedback. To alleviate the problem of limited labeled data, it is important to combine contents and this new (but weak) type of information as supervision signals, i.e., weak social supervision, to advance fake news detection. The goal of this dissertation is to understand disinformation by proposing and exploiting weak social supervision for learning with little labeled data and effectively detect disinformation via innovative research and novel computational methods. In particular, I investigate learning with weak social supervision for understanding disinformation with the following computational tasks: bringing the heterogeneous social context as auxiliary information for effective fake news detection; discovering explanations of fake news from social media for explainable fake news detection; modeling multi-source of weak social supervision for early fake news detection; and transferring knowledge across domains with adversarial machine learning for cross-domain fake news detection. The findings of the dissertation significantly expand the boundaries of disinformation research and establish a novel paradigm of learning with weak social supervision that has important implications in broad applications in social media. / Dissertation/Thesis / Doctoral Dissertation Computer Science 2020

Dezinformace jako společenský fenomén: Případová studie Truth Decay na Slovensku / Disinformation as a Societal Phenomenon: A Case Study of Truth Decay in Slovakia

Húsková, Eva January 2021 (has links)
The main purpose of this master's thesis is to offer a deeper understanding of disinformation trends and their causes in Slovakia by utilizing the theoretical and analytical framework of the concept of Truth Decay defined by the RAND Corporation in 2018. At the same time, the work also contributes to the exploration of the phenomenon of Truth Decay in general. The research stems from a premise that disinformation should not be strictly perceived as a tool of hybrid warfare. Hence, there is an increasing need to analyze disinformation as a wider societal problem that leaves its marks on society in different ways. Based on 11 expert interviews with professionals with different backgrounds (academia, think tanks, government institutions, security institutions, journalism, or psychology), this master's thesis consists of two main analytical chapters. The first one analyzes four trends of Truth Decay in a Slovak setting: an increasing disagreement about facts and analytical interpretations of facts and data; a blurring of the line between opinion and fact; an increase in the relative volume, and resulting influence, of opinion and personal experience over fact; and lowered trust in formerly respected sources of factual information. The second analytical chapter is focusing on possible drivers of these...

The Peru approach against the COVID-19 infodemic: Insights and strategies

Alvarez-Risco, Aldo, Mejia, Christian R., Delgado-Zegarra, Jaime, Del-Aguila-Arcentales, Shyla, Arce-Esquivel, Arturo A., Valladares-Garrido, Mario J., Del Portal, Mauricio Rosas, Villegas, León F., Curioso, Walter H., Sekar, M. Chandra, Yáñez, Jaime A. 01 August 2020 (has links)
The COVID-19 epidemic has spawned an "infodemic,"with excessive and unfounded information that hinders an appropriate public health response. This perspective describes a selection of COVID-19 fake news that originated in Peru and the government's response to this information. Unlike other countries, Peru was relatively successful in controlling the infodemic possibly because of the implementation of prison sentences for persons who created and shared fake news. We believe that similar actions by other countries in collaboration with social media companies may offer a solution to the infodemic problem. / Revisión por pares

Analýza sítě expertů na informační válku v České republice / Analysis of the network of information war experts in the Czech Republic

Kohút, Martin January 2018 (has links)
The rise of 'information disorder' that undermine Western political principles has become one of the key political concerns in current Europe and United States and led to searching for new solutions how to fight the spread of mis- and dis-information. While the nature of this danger is still subject to much debate, we can already observe a rise of new experts explaining the threat of information war and how to deal with it. This research looks at how this novel problematization of security affects the politics of security expertise. Or, who gains power in this 'battle for truth'? Building on sociological approaches in security studies, this thesis focuses on the Czech Republic as a country that has become very active in the fight against disinformation and analyses the network of actors recognized as providing security expertise on information warfare. Based on social network analysis, the research maps the structure of social relations among actors recognized as experts and points out the empowerment of think-tanks and journalists, who build their expertise by bringing together their social capital, bridging knowledge of Russian politics and the new media environment, and introducing new practices to make the society resilient towards information warfare.

Boj proti desinformačním kampaním: přehodnocení strategické komunikace / Combatting Disinformation Campaigns: A Reappraisal of Strategic Communications

Wilson, Alyssa Joy January 2019 (has links)
In the context of increasing technologicalization and the growing interconnectedness of our world through social media, this thesis aims to answer the question, why is disinformation not being sufficiently handled in the United States in the wake of the foreign meddling in the 2016 Presidential Elections, and what can and should be done about the threat? This master thesis therefore aims to delve into the inherent vulnerabilities in the U.S. societal fabric, and thus conduct an in-depth explanatory case study model analysis of what should be done to further combat and counteract disinformation and election meddling within the country. The author argues that disinformation and election meddling are not only a serious security threat, but are also not being properly handled as they are only being addressed technologically, and not through the realm of information, and societal resilience. This thesis therefore argues that strategic communication, which should be redefined and expanded in definition, should be used to combat disinformation campaigns to prevent further election meddling. The author posits that a two-level approach is best, one which aims to negate the negative disinformation campaigns through a single governmental body, while also addressing the root causes through education.

Fotografie a její autenticita v kontextu debaty o šíření dezinformací v online prostředí / Photography and its authenticity in the context of the debate about disseminating disinformation in the online environment

Cengrová, Michaela January 2019 (has links)
The submitted thesis focuses on the photograph and its role in the process of disseminating disinformation in the online environment. The thesis deals with the opinion that, despite the fundamental changes in the understanding of photography and its credibility, which together with the transition from its analogue form to digital one, photography retains the status of an authentic medium. For this reason photography is becoming a very powerful tool for spreading misinformation. The thesis deals with the theoretical basis of objectivity of photography, its documentary value and expectation of authenticity. The role of the context, which is crucial for understanding the photographic message, will be emphasized. The thesis also defines the basic concepts related to the phenomenon of disinformation. The strategies used to spread disinformation via photography is also presented. In the practical part of the thesis particular disinformative photographic messages is analyzed. Ways to verify the authenticity of particular photographic images are presented. Keywords: photography, authenticity, disinformation, hoax, fake news, online environment, manipulation

Žánry falešného zpravodajství / Fake news genres

Prokypčák, Matej January 2019 (has links)
The diploma thesis consists of two main parts. In the theoretical part, we deal with the basic terminological framework of fake news, the development of misinformation, fake news, hoaxes, propaganda and their form and the form they acquired. We will also look at misinformation, hoax and propaganda as a specific genre of false news. Furthermore, we analyze the spread of hoaxes and disinformation and the criteria by which hoaxes are recognized and labeled. An important part of the theoretical part of the thesis is also the manipulation with the content and the determination of the criteria on the basis of which false information can be recognized. We will focus primarily on the electronic and new media domains, which are mainly represented by social networks. In the research and analytical part of the thesis we look at the ways in which different sites classify misinformation and hoaxes, by what criteria they approach their classification, and whether these methods are unambiguous and consistent. The second important part of the research will analyze the attitudes of traditional and alternative media to work with false news and hoaxes. We will try to bring a glimpse of both stakeholders, that is to say, representatives of traditional media and alternative media.
