Abstract

fetched live from OpenAlex

Cet article présente les résultats d’une recherche ayant pour objectif de recenser les caractéristiques de deux approches utilisées pour l’indexation d’un ensemble d’images ordinaires représentant des objets de la vie quotidienne. La première approche suppose l’attribution de termes d’indexation extraits d’un dictionnaire visuel, alors que la deuxième approche préconise l’utilisation du vocabulaire libre pour la description des images. L’analyse des termes d’indexation révèle les tendances observées sur le plan terminologique, perceptuel et structurel. Les facteurs ayant influencé l’attribution des termes d’indexation sont également décrits.

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.
