What Is Entity Extraction?
Entity Extraction, also known as Named Entity Recognition (NER), is a natural language processing technique used to detect and classify important pieces of information within unstructured text. It breaks down sentences to find entities like people’s names, organizations, locations, dates, and other specific terms that hold meaning. By converting raw text into structured data, entity extraction helps machines understand context and relevance more effectively.
