Abstract

fetched live from OpenAlex

Dans le cadre d’un projet de recherche récemment complété, nous nous sommes intéressés au lexique et à la structure des langages documentaires utilisés pour représenter le contenu d’images en mouvement décrivant des objets et des situations de la vie courante. Onze organismes, gérant quatorze collections d’images ont répondu à un questionnaire et ont été visités. Les données recueillies ont permis de constater que les collections sont imposantes et qu’au moins la moitié d’entre elles sont indexées au niveau du plan à l’aide d’outils langagiers plus ou moins contrôlés, souvent un thésaurus. Mais malgré la similarité des collections, les divers lexiques montrent peu de recoupements. Les collections d’images en mouvement sont encore décrites et indexées selon des principes et des techniques établis localement, peu normalisés et rarement compatibles.

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.
