• CURIE: gmeow:DefeaterKind
• IRI: https://blackcatinformatics.ca/gmeow/DefeaterKind
• Category: class
• Defined by: gmeow:slices/inference
• Box roles: TBox role (What is this?)

The Pollock kind of a defeater — a value vocabulary (individuals, never subclasses): gmeow:defeaterRebutting (attacks the conclusion directly, giving reason to believe its negation) and gmeow:defeaterUndercutting (attacks the inferential link, removing the warrant without asserting the negation). Carried as a gmeow:defeaterKind value on a defeating gmeow:StandpointClaim.

Structure

Subclass of: gufo:QualityValue

Practical Pattern

Use gmeow:DefeaterKind as a specialized kind of gufo:QualityValue. Add statement metadata or a standpoint when the assertion needs provenance, confidence, or vantage.
