Fact-checking verifies a multitude of claims and remains a promising solution to fight fake news. The spread of rumors, hoaxes, and conspiracy theories online is evident in times of crisis, when fake news ramped up across platforms, increasing fear and confusion among the population as seen in the COVID-19 pandemic. This article explores fact-checking initiatives in Latin America, using an original Markov-based computational method to cluster topics on tweets and identify their diffusion between different datasets. Drawing on a mixture of quantitative and qualitative methods, including time-series analysis, network analysis and in-depth close reading, our article proposes an in-depth tracing of COVID-related false information across the region, comparing if there is a pattern of behavior through the countries. We rely on the open Twitter application programming interface connection to gather data from public accounts of the six major fact-checking agencies in Latin America, namely Argentina (Chequeado), Brazil (Agência Lupa), Chile (Mala Espina Check), Colombia (Colombia Check from Consejo de Redacciín), Mexico (El Sabueso from Animal Polótico) and Venezuela (Efecto Cocuyo). In total, these profiles account for 102,379 tweets that were collected between January and July 2020. Our study offers insights into the dynamics of online information dissemination beyond the national level and demonstrates how politics intertwine with the health crisis in this period. Our method is capable of clustering topics in a period of overabundance of information, as we fight not only a pandemic but also an infodemic, evidentiating opportunities to understand and slow the spread of false information.

– Many scholars have recognized the benefits that user-generated content (UGC) can bring to news publications. In this context, the coverage of the pandemic has undoubtedly forced news outlets around the world to embrace such content to present relevant information during this time. To understand how Latin American outlets are exploring UGC in news reporting, we proposed an exploratory study that includes a devised observation of 80 news websites and their social network channels between April and August 2020. During this period, we conducted a systematic observation to analyze how these outlets open spaces for the public and experiment with integrating user content into their news processes. Our findings suggest that the majority of the observed portals have punctually adopted UGC with minimal engagement. However, the pandemic disrupted interesting experiments regarding the integration of UGC into news creation that generate innovative forms of storytelling.RESUMO – Muitos acadêmicos têm reconhecido os benefícios que o conteúdo gerado pelo usuário (CGU) pode trazer para as notícias. Nesse contexto, a cobertura da pandemia, sem dúvida, forçou os meios de comunicação de todo o mundo a adotar esse tipo de conteúdo para apresentar informações relevantes durante esse período. Para entender como os veículos latino-americanos estão explorando o CGU em reportagens, propusemos um estudo exploratório que inclui uma observação planejada de 80 sites de notícias e seus canais de rede social entre abril e agosto de 2020. Durante esse período, conduzimos uma observação sistemática para analisar como esses veículos abrem espaços para o público e experimentam integrar o conteúdo do usuário em seus processos de notícias. Nossos resultados sugerem que a maioria dos portais observados adotou CGU pontualmente com envolvimento mínimo. No entanto, a pandemia promoveu experimentos interessantes sobre a integração de CGU na criação de notícias que resultaram em formas inovadoras de storytelling.RESUMEN – Los estudios académicos han reconocido los beneficios que el contenido generado por el usuario (CGU) puede aportar a las noticias.

Nuestros hallazgos sugieren que la mayoría de los portales observados adoptan puntualmente el CGU con un compromiso mínimo. Por otro lado, la pandemia ha disrumpido algunos experimentos interesantes de integración del CGU en la creación de noticias que generaron formas innovadoras de storytelling.
