Abstract

fetched live from OpenAlex

Cette étude explore les pratiques courantes d'indexation du contenu thématique d'images historiques. Elle examine la façon dont la tradition positiviste en bibliothéconomie et sciences de l'information exerce une influence sur les indexeurs au moment où ils déterminent les thèmes devant être indexés. Les termes utilisés par les indexeurs comme thèmes sont analysés par niveau de facette de sujet afin de déterminer l'étendue de contenu thématique indéxé aux fins de repérage d'information.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
