AI process distinguishing your entity from similarly-named ones. Prevent failure through: consistent NAP (Name-Address-Phone) across all sources, complete schema.org markup, comprehensive sameAs linking, Wikidata item, unique visual identity. Common failure: multiple entities share name, AI can’t determine which is meant, omits all. Test: query ambiguous reference to your entity, check if AI correctly identifies you. Disambiguation failure = invisibility. Strengthen through KGMID assignment, distinctive termCode usage, and temporal consistency.
