This paper introduces a novel approach to managing identity and ontology tagging within a production knowledge graph, focusing on the critical stage of data ingestion. It details a system designed to prevent destructive merge errors by employing a record-identity ladder that prioritizes identifier columns and name matching over simple similarity. The research also addresses multi-class ontology tagging, proposing a method that requires anchored evidence to avoid misclassifications and improve role assignments. The authors quantify the graph's conformance debt and describe a significant backlog of curation proposals. AI
