typicality

• CURIE: gmeow:typicality
• IRI: https://blackcatinformatics.ca/gmeow/typicality
• Category: property
• Defined by: gmeow:slices/concepts
• Box roles: RBox role (What is this?)

A graded degree of membership in [0,1] for a prototype-theoretic concept, attached to a reified gmeow:ConceptCategorization. Non-functional: multiple sources may report typicality, and those reports coexist (Principle 9). Solver-layer prototype-theoretic typicality; it is not a reasoner entailment.

Structure

Property shape: datatype property; gmeow:ConceptCategorization -> xsd:decimal

Practical Pattern

Use gmeow:typicality from gmeow:ConceptCategorization to xsd:decimal when the relationship itself belongs in the native GMEOW graph.

Usage Advice

Use when

• Use to record graded membership of an entity under a prototype-theoretic concept when the degree itself is first-class.

Avoid when

• Avoid on the flat gmeow:instanceOfConcept shortcut (promote to a ConceptCategorization first) and avoid conflating it with gmeow:confidence (our certainty about the claim) or gmeow:claimModality (the standpoint's qualitative stance).

How to use

• Attach one or more xsd:decimal values in [0,1] to a gmeow:ConceptCategorization; pair with gmeow:claimModality on the linked StandpointClaim for qualitative categorization stance.

Examples

• ex:whaleCategorization gmeow:typicality "0.95"^^xsd:decimal.
