Definition
Named entity recognition, or NER, is the natural language processing task of finding the proper nouns in a text and sorting them into types, people, organizations, places, products, and marking each place they appear. It is the operation this glossary also files under entity recognition. NER is the name the field uses most.Why It Matters for AI Search
Before a system can reason about a brand as an entity, it has to find the brand’s name in running text and know the name refers to a thing rather than a stray word. NER is that first step, the point where unstructured prose becomes a set of identified entities a knowledge graph can absorb. Errors here carry forward: a name missed or miscategorized is an entity the system cannot connect, cite, or recommend. Writing that states entity names plainly and consistently gives an NER model less to guess at, which is the quiet groundwork of being recognized at all.Related Terms
