## Definition

Entity linking is the process of connecting a mention of an entity in text to its canonical record in a knowledge base — mapping "Apple" in a sentence to the Apple Inc. entry in a knowledge graph, for example, rather than to the fruit.

## Why It Matters for AI Search

Entity linking is how AI systems resolve ambiguity at the document level. Content that includes disambiguating context — full company names, location references, industry terms, and sameAs markup — makes entity linking more accurate and reduces the risk of a brand mention being attributed to the wrong entity. For brands with common or ambiguous names, explicit disambiguation is one of the highest-leverage entity optimization moves available.
