Abstract

fetched live from OpenAlex

A framework has been proposed for evaluating queries in a deductive database system. The framework is based on modeling the intentional database rules and the extensional database relations by using a special class of petri nets called predicate/transition nets. A system of communicating processes is then derived from the predicate/transition net model. Thus, parallel query evaluation becomes the issue of how concurrent processes compute intermediate relations based on the given extensional database relations, communicate and synchronize with each other through message passing to produce the evaluation result. In the framework, the AND/OR parallelisms are exploited with the augmentation of the heuristics of maximizing the bound arguments and utilizing the sideways information passing to restrict the computation to generating those portions of intermediate relations that are relevant to the query. The research results have indicated that the framework is sound and complete and lends itself to a parallel implementation.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
