Definition

Entity disambiguation is the process of distinguishing between multiple entities that share the same or similar names — ensuring AI systems associate content with the correct entity rather than a homonym or similarly named competitor. It is achieved through structured data, sameAs links, and explicit context signals. Entity disambiguation is especially important for brands with common or generic names. Without disambiguation signals, AI systems may conflate a small Hawaii agency with a similarly named company elsewhere — producing incorrect, mixed-up brand characterizations. Disambiguation through Wikidata entries, Wikipedia articles, and schema markup with sameAs links to authoritative identifiers gives AI systems the unambiguous identity anchors needed to resolve references correctly.
