Abstract
Les schémas de classification encyclopédiques qui servent encore à l’organisation intellectuelle et physique des ressources documentaires dans nos bibliothèques, et de plus en plus fréquemment sur Internet, sont maintenant plus que centenaires. Sans être les dinosaures que d’aucuns se plaisent à décrire, ces systèmes sont néanmoins marqués de rides profondes qu’un épais maquillage technologique n’arrive pas toujours à masquer. Dans cet article, nous décrirons les efforts d’amélioration de la performance de ces schémas d’organisation des disciplines et des sujets, efforts qui s’actualisent dans des projets de recherche et développement portant sur les contenus et les structures, ainsi que sur les interfaces qui permettent au chercheur d’information de mieux profiter des avantages offerts par la structuration hiérarchique. Nous aborderons principalement les travaux qui s’effectuent présentement sur la Classification décimale Dewey (CDD) et sur la Classification de la Library of Congress, mais nous toucherons aussi la Classification décimale universelle (CDU) ainsi que la classification à facette de Ranganathan.

How this classification was reachedexpand
Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
