explanatory score

A solver-computed score of how well a candidate hypothesis explains its explanandum (simplicity, scope, coherence) — the basis on which inference-to-the-best-explanation ranks rivals. A solver-layer value (Principle 12), not an asserted truth: there is no isBest bit; the ranking promotes the winner's modality and suppresses the losers. NOT functional.

Structure

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

Practical Pattern

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

# Worked example — ABDUCTION (inference to the best explanation), the FULL CHAIN.
#
# This example exercises all three fidelity tiers and the endurant/occurrent
# split end to end:
#
#   gmeow:InferenceProcess  --hasInferenceCommitment-->  gmeow:InferenceCommitment
#       (the occurrent reasoning episode)                  (the endurant argument)
#            |                                                   |
#       producesMentalMoment                               conclusion
#            v                                                   v
#       the accepted belief        is the agent's attitude    gmeow:StandpointClaim
#       (gmeow:MentalMoment)        toward the winning ------> (the conclusion content)
#                                   hypothesis
#
# A clinician observes a fever and reasons to its best explanation. Two
# candidate hypotheses compete (gmeow:competesWith); each is scored by a
# solver-layer gmeow:explanatoryScore (Principle 12 — there is no isBest bit).
# The winner's modality is promoted gmeow:conceivable -> gmeow:probable; the
# loser is SUPPRESSED (gmeow:displayable false), never deleted (Principle 10).

# Winner: influenza — best explains the high fever; promoted to probable.
