Abstract

fetched live from OpenAlex

We design a representation based on the situation calculus to facilitate development, maintenance and elaboration of very large taxonomies of actions. This representation leads to more compact and modular basic action theories (BATs) for reasoning about actions than currently possible. We compare our representation with Reiter’s BATs and prove that our rep-resentation inherits all useful properties of his BATs. More-over, we show that our axioms can be more succinct, but ex-tended Reiter’s regression can still be used to solve the projec-tion problem (this is the problem of whether a given logical expression will hold after executing a sequence of actions). We also show that our representation has significant compu-tational advantages. For taxonomies of actions that can be represented as finitely branching trees, the regression oper-ator can work exponentially faster with our theories than it works with Reiter’s BATs. Finally, we propose general guide-lines on how a taxonomy of actions can be constructed from the given set of effect axioms in a domain.

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.
