La notion de division tolérante et son intérêt pour remédier aux réponses vides
Bibliographic record
Abstract
In this paper, queries involving preferences are considered. Preferences are conveyed thanks to fuzzy predicates whose truth values are a matter of degree. In this framework, the result of a query is no longer a flat set of elements and each component of the answer is assigned a level of satisfaction. However, if such answers are expected to be more satisfactory from a user point of view, empty answers may still occur. The focus of the paper is put on empty answers to queries involving a division, operator which plays a central role far beyond relational database systems, especially in information retrieval systems or Web searches. In the case of an empty answer, the approach suggested here is to weaken the division and different rationales for that are proposed and discussed. It is worth mentioning that most of these weakening mechanisms are also valid for the division of regular relations.

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.
