METABOLOMICS KNOWLEDGE GRAPH

Papers: 1,287

Claims: 8,761 (unique assertions, deduplicated)

Physical claims: 5,470 (MetaboLights deposit verified)

EXPERIMENT RESULTS

Hypothesis: pCite surfaces physically-validated claims better than traditional citation count.

Mann-Whitney U	p = 0.00e+00 ✓ significant
Precision@50	pCite 0.94 vs Traditional 0.50 (1.9× lift)
NDCG@50	pCite 0.94 vs Traditional 0.60

Hypothesis holds.

VALIDATION CLASS DISTRIBUTION

Physical5,470 62.4%

Replicated25 0.3%

DB Referenced2,661 30.4%

Text Derived605 6.9%

The distribution is the argument. 7% of extracted claims have no physical anchor. Under traditional citation metrics, these claims are indistinguishable from the 62.4% that do.
