Named Entity Recognition (NER) — AI Glossary

Identifying and categorizing named entities (persons, organizations, locations, dates) in text. Traditional: fine-tuned BERT/RoBERTa on CoNLL-2003.

Overview

NER is a foundational NLP task: token-level classification into entity types (PER, ORG, LOC, DATE, PRODUCT). Traditional: fine-tuned BERT/RoBERTa on CoNLL-2003. LLM-based: zero-shot NER via prompting achieves near-SoTA without labeled data. Used in legal document analysis, news extraction, and medical record processing.
