distance metric
- CURIE:
gmeow:distanceMetric - IRI: https://blackcatinformatics.ca/gmeow/distanceMetric
- Category: property
- Defined by:
gmeow:slices/graphrag - Box roles: RBox role (What is this?)
The similarity/distance function under which an embedding or index is meaningful — cosine and euclidean disagree about what is 'near', so the metric is provenance, not a detail. Domain-free: carried by Embedding and VectorIndex alike.
Structure
Property shape: object property; ? -> gmeow:DistanceMetric; functional
Practical Pattern
Use gmeow:distanceMetric from ? to gmeow:DistanceMetric when the relationship itself belongs in the native GMEOW graph.
