Every category in the CategoryRank Ontology, ranked by vocabulary fragmentation between OEM, distributor, AI, and aggregator voices. The higher the score, the wider the misalignment — and the deeper the opportunity for a sourcing desk that can bridge it. The fragmentation index refreshes on a slower cadence than the weekly rank boards.
