entity linking
noun

Definition:
The process of identifying and disambiguating mentions of entities (such as people, organizations, places, or concepts) in text and associating them with their corresponding entries in a structured knowledge base (e.g., Wikipedia, Wikidata). Entity linking enhances machine understanding by resolving ambiguous references and grounding text to canonical data, improving tasks like information retrieval, question answering, and content classification.

Usage:
“To improve the accuracy of its AI responses, the system used entity linking to connect the mention of ‘Apple’ to the technology company rather than the fruit.”
