Abstract

fetched live from OpenAlex

Using a relational approach, we investigate the implication problem for dependencies for information relations, focusing on functional dependencies, association rules and multivalued dependencies. We develop a Rasiowa/Sikorski-style relational calculus and show that the associated tableaux style of reasoning gives a decidable procedure for each of the three kinds of inference problems under consideration. This work has applications to classical database theory and to Rough Set Theory. The techniques may be generalized to the many other data dependencies which have formulations via binary relations and they can be applied to other information relations which arise in the study of incomplete 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.
