A Named Entity is a real-world object or concept denoted by a proper noun—typically a person, organisation, location, geopolitical entity, date, time expression, monetary value, or product—that can be identified and classified within text by a named-entity recognition system. Named entities form the primary subjects, objects, and contextual anchors of factual statements, making their accurate identification a prerequisite for downstream information-extraction, relation-extraction, question-answering, and knowledge-graph construction tasks. The boundary and category of a named entity are determined by an annotation schema and domain ontology, so the same text span may be categorised differently across biomedical, legal, and news domains.
