Abstract

fetched live from OpenAlex

Em meio à pandemia do novo coronavírus (Covid-19), a explosão de informações nas mídias a respeito da doença tem intensificado a produção e disseminação de notícias falsas. Dessa forma, este trabalho, apoiado na abordagem qualitativa de pesquisa, objetivou analisar a formação crítica do leitor à reflexão dos fatores pragmáticos da textualidade na produção de fake news sobre a Covid-19. São objetos de análise três publicações sobre a cura do coronavírus mediante insumos caseiros. Essas publicações foram checadas pelo site do Ministério da Saúde e comprovadas como fake news. A pesquisa foi embasada na Linguística Textual sob os fundamentos teóricos de Costa Val (1991; 2008), Koch e Travaglia (1993; 2015), Marcuschi (2008), Koch (2014), Koch e Elias (2008), Rodrigues et al. (2009); Santaella (2018), Leite (2019) e Galhardi et al. (2020), Bauman (2001) sobre fake news e sua intensificação. Constatou-se que a formação crítica dos leitores ainda é limitada, pois os produtores de fake news se valem dos fatores pragmáticos da textualidade para atribuir sentidos ao que se enuncia sobre a Covid-19 e ganham à cooperação do leitor na aceitação dos seus conteúdos. Logo, essa interação autor/texto/leitor dificulta o combate à crise sanitária no Brasil.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
