Development of modular ontologies in Casl
Bibliographic record
Abstract
Abstract. This paper discusses the advantages of the Common Algebraic Specification Language (Casl) for the development of modular ontologies. Casl not only offers logics with a limited expressivity like description logic, but also e.g. first-order logic and modal logic. The central part of Casl is its powerful structuring mechanism, which is orthogonal to the logical formalisms. Hence the modularization applies uniformly to various logics and its extension Heterogeneous Casl (HetCasl) has even constructs for the combination of different logics. Additionally, the Heterogeneous Tool Set (Hets) is presented which enables reasoning and manipulation of Casl specifications. By presenting a detailed example ontology used for spatial knowledge representation the benefits of specification in Casl are discussed. Furthermore, a comparison with the OWL DL import mechanism is provided. 1

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.
