SKC Metrics

SKC evaluates compression together with reconstruction and semantic preservation.

The current validation vocabulary includes the following metrics.

BlueprintSize

Size of the reference representation before semantic-core reduction.

BlueprintSize

This establishes the baseline against which reduction can be measured.

SemanticCoreSize

Size of the reduced semantic representation.

SemanticCoreSize

ReductionRatio

Measures the fraction removed from the original representation.

Conceptually:

ReductionRatio =
1 - (SemanticCoreSize / BlueprintSize)

CompressionRatio

Expresses the relationship between original and reduced representation.

Conceptually:

CompressionRatio =
BlueprintSize / SemanticCoreSize

ReconstructionFidelity

Measures how successfully required semantic structure survives reconstruction.

A high compression ratio without sufficient reconstruction fidelity is not a successful SKC result.

GraphEquivalence

Reports whether the reconstructed semantic graph satisfies the declared equivalence contract.

SemanticEntropy

A research metric for characterizing information density or semantic complexity within the representation.

Its precise interpretation must remain tied to the SKC version and metric definition used by the experiment.

Deterministic

Indicates whether repeated processing under the same defined inputs and environmental contract produces equivalent results.

Metric set

A useful SKC validation result therefore looks conceptually like:

{
  "BlueprintSize": 0,
  "SemanticCoreSize": 0,
  "ReductionRatio": 0.0,
  "CompressionRatio": 0.0,
  "ReconstructionFidelity": 0.0,
  "GraphEquivalence": false,
  "SemanticEntropy": 0.0,
  "Deterministic": false
}

The values above are intentionally placeholders, not benchmark claims.

Principle

Compression is only meaningful when preservation is measured.
