Abstract

fetched live from OpenAlex

Active databases are usually centered around the notion of Event-Condition-Action (ECA) rules. An ECA rule's action is executed upon detection of an event whenever the rule's condition is true. Events are traditionally described using an event algebra. Virtually every proposed active database management system (ADBMS) brings about a different event algebra. This makes it very difficult to analyze these proposals in a uniform way by spelling out what they may have in common, or how they may differ. Typically, logic might act as a framework for dealing with these issues. This paper treats events as (somewhat constrained) formulas of the situation calculus, a (second order) logic for reasoning about actions in general, and database updates and transactions in particular. We provide a framework for devising the semantics of complex events in this logic. Such semantics, formulated as theories of a special kind, are used for reasoning about the occurrence and consumption modes, which are an important dimension of events.

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.
