Normalization Pipeline

The normalization pipeline shows how data flows from the original knowledge graph through transformation and normalization stages.

Epistemic Robustness measures the provenance quality of edges from this knowledge graph, using Knowledge Level and Agent Type from the Biolink Model to assess evidence strength and reliability. Higher scores indicate stronger evidence and greater manual curation.

Edge Type Validation

This section shows the validation of edge types from this knowledge graph against the recognized biolink schema patterns.

No edge validation data available for this knowledge graph.

ABox / TBox Classification

The TBox-to-ABox balance reflects how much a knowledge graph emphasizes abstract schema versus concrete instances—too much of either can hinder effective learning and reasoning.

No ABox/TBox data available for this knowledge graph.
