Query matrix
Dimensions
Up to three lemma-POS-span queries that should match are selected from one source sentence. Each is paired with a same-POS query that should not match.
Nominal and predicate classes, particles, endings, irregulars, compounds, explicit POS, and boundary policies are crossed.
Each case declares an expected match, expected no match, and optional contract disposition.
Coverage
The evaluator aligns backend candidates to cases and distinguishes partial spans, crossings, and extra matches. Candidate coverage below 100% blocks approval.
Aggregate F1 is accompanied by per-dimension TP, FP, and FN so a missing rule remains identifiable.
The query matrix is a diagnostic workload and neither replaces nor merges with the Canonical regression baseline.
Disposition ledger
Raw and adjusted matrices use the same predictions. The registry stores confirmed, reclassified, and excluded reasons by case ID in version control.
FNᶜ = 0 means there is no classified in-contract false negative. Raw FN and unclassified counts remain visible.
