Abstract

fetched live from OpenAlex

Uma importante dimensao a ser considerada na construcao de normalizacoes para os estudos do trabalho no passado brasileiro diz respeito a codificacao das ocupacoes declaradas na documentacao pre-censitaria ou nos primeiros censos nacionais (sobretudo aqueles anteriores a 1940). Pretende-se apresentar a versao brasileira, ainda em construcao, da base de dados de classificacao de ocupacoes denominada RISCO. Tal base de dados pretende adaptar, para periodos historicos, a International Standard Classification of Occupation (ISCO), que e a base da Classificacao Brasileira de Ocupacoes (CBO), utilizada contemporaneamente pelo Instituto Brasileiro de Geografia e Estatistica (IBGE) e outros orgaos produtores de estatisticas. Trata-se de um projeto internacional envolvendo historiadores e cientistas sociais de diversos paises (Belgica, Gra-bretanha, Canada, Franca, Alemanha, Holanda, Noruega, Suecia, Portugal, Espanha, Dinamarca, India, Russia, Filipinos e Grecia). A insercao brasileira toma-se relevante tendo em vista o desenvolvimento posterior de estudos comparados, tanto ao tempo quanto ao espaco, ja que se parte de uma mesma logica de codificacao para classificar as ocupacoes de diferentes periodos historicos e de diversos paises. A base de dados brasileira toma como ponto de partida listas de habitantes do seculo 19, sobretudo Sao Paulo, em 1836, mas tambem outras fontes de outros estados brasileiros.

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.
