This article presents the classification of fakes on grounds of the information source that underlies the occurrence of false information. The study was perfomed on the coronavirus fakes that spread in Russian Federation in March 2020 during the beginning of the coronavirus pandemic in our country. For the analysis, only those fakes were taken, which the Administrations of the Russian regions promptly denied in their official accounts on social networks. Based on this, only those fakes that caused the greatest public response were selected for analysis. In this article, the following types of fakes are distinguished: folklore, symmetric, interpretive, additional, and conspiracy. Folklore fakes in various variations reproduce the same motives and are associated with well-established ideas and stereotypes in the mass consciousness. Symmetrical fakes partially or completely transfer true facts from one territory (country, region) to another. They can also transfer information from one person (structure) to another (s). Interpretative fakes are associated with the incorrect interpretation of events, information disseminated, or decisions made by the authorities by individual individuals. Additional fakes for a short period of time continue the theme of previously thrown disinformation. Conspiracy fakes are associated with conspiracy theory, characterized by stuffing on a wide territory and a large audience This classification is not exhaustive and can be supplemented as new fakes appear and are studied. Also, within the framework of this article, recommendations are given on how to refute a particular fake, depending on its belonging to a particular type.

Conspiracy theories in social networks are considered to have adverse effects on individuals' compliance with public health measures in the context of a pandemic situation. A deeper understanding of how conspiracy theories propagate through social networks is critical for the development of countermeasures. The present work focuses on a novel approach to characterize the propagation of conspiracy theories through social networks by applying epidemiological models to Twitter data. A Twitter dataset was searched for tweets containing hashtags indicating belief in the ``5GCoronavirus'' conspiracy theory, which states that the COVID-19 pandemic is a result of, or enhanced by, the enrollment of the 5G mobile network. Despite the absence of any scientific evidence, the ``5GCoronavirus'' conspiracy theory propagated rapidly through Twitter, beginning at the end of January, followed by a peak at the beginning of April, and ceasing/disappearing approximately at the end of June 2020. An epidemic SIR (Susceptible-Infected-Removed) model was fitted to this time series with acceptable model fit, indicating parallels between the propagation of conspiracy theories in social networks and infectious diseases. Extended SIR models were used to simulate the effects that two specific countermeasures, fact-checking and tweet-deletion, could have had on the propagation of the conspiracy theory. Our simulations indicate that fact-checking is an effective mechanism in an early stage of conspiracy theory diffusion, while tweet-deletion shows only moderate efficacy but is less time-sensitive. More generally, an early response is critical to gain control over the spread of conspiracy theories through social networks. We conclude that an early response combined with strong fact-checking and a moderate level of deletion of problematic posts is a promising strategy to fight conspiracy theories in social networks. Results are discussed with respect to their theoretical validity and generalizability.

The Given

Unlike the previous works where detecting communities is performed on large graphs, our approach considers textual documents for discovering potential social networks. More precisely, the aim of this paper is to extract social communities from a collection of documents and a query specifying the domain of interest that may link the group. We propose a methodology that develops an information retrieval system capable to generate the documents that are in relationship with any topic. The authors of these documents are linked together to constitute the social community around the given thematic. The search process in the information retrieval system is designed using BSO, the bee swarm optimization method in order to optimize the retrieval time for large amount of documents. Our approach was implemented and tested on CACM and DBLP and the time of building a social network is quasi instant.

Objective: To demonstrate the importance of Fact-Checking tools in combating health fake news in the COVID-19 pandemic. Methods: Quantitative descriptive study, conducted during the Sars-Cov-2 pandemic. Fake news were accounted and identified through the website chequeado.com, registered in the Agência Lupo and Aos Fatos checking platforms, belonging to the International Fact-Checking Network, an international understanding with recognized news verification methodologies. The registered news originated from the social media/networks Facebook, Whatsapp, Instagram, Twitter, and websites. They were later classified according to content in Conspiracy Theory, Prevention/Treatment/Cure, Authorities/Agency Measures, Situation of a city, state and country, Causes, Symptoms, Public Figure and False Context. Results: 529 fake news about coronavirus were obtained, of these 306 were from the Agência Lupo platform, and 223 from the Aos Fatos platform. A total of 99 (18.72%) fake news were about Conspiracy Theory 99 (18.72%) Authorities/Agency Measures and 98 (18.53%) False Context. As for the origin of fake news 382 (72.21%) were from Facebook and 67 (12.66%) from Whatsapp. Conclusion: The Fact-Checking tools in combating misinformation on social networks are important because they deny false news, unlikely allegations, and no justification related to the Covid-19 pandemic. These check sites alert social networks, policymakers, and the public to create measures that educate and protect the integrity and health of individuals and prevent them from falling victim to misinformation.
