Abstract

fetched live from OpenAlex

As redações jornalísticas têm modificado suas estruturas, físicas e organizacionais, a fim de\nse adequarem às inovações tecnológicas, às novas exigências do mercado de trabalho e aos perfis\nmutáveis dos públicos consumidores. Com a popularização da Internet, muitos jornalistas precisam\nproduzir materiais tanto para a mídia impressa, como também para veículos online. Nesta\nmonografia, foi apresentada uma análise de conteúdo das capas impressas e home pages de seis\njornais de grande porte: The New York Times, The Washington Post, Ottawa Citizen, Toronto Star,\nFolha de São Paulo e O Estado de São Paulo. Com base nos registros feitos pelo aplicativo Google\nInsight for Search, foi observada a utilização de palavras-chave mais procuradas e de palavraschave\ncom aumento repentino, nas capas impressas e nas home pages dos veículos de comunicação\ncitados. Outro ponto analisado foi a presença de valores-notícia nas palavras-chave utilizadas. Os\nresultados obtidos mostraram que, na maioria dos casos estudados, as home pages utilizaram mais\npalavras-chave nas capas impressas de seus respectivos veículo de comunicação. Além disso, em\nquase metade das home pages estudadas, houve maior presença de palavras-chave não relacionadas\na valores-notícia, do que palavras-chave com valores-notícia agregados.

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.
