Named Entity Recognition (NER)
Named entity recognition (NER) is a natural language processing task that identifies and classifies named entities in text into predefined categories such as persons, organizations, locations, dates, and domain-specific entities.
理解する Named Entity Recognition (NER)
NER is one of the foundational tasks in NLP, enabling systems to convert unstructured text into structured data. A classic NER system identifies proper nouns and classifies them: a person's name, a company name, a date reference. Modern LLM-based NER extends this to domain-specific categories and understands context — distinguishing between Apple the company and apple the fruit based on surrounding sentences. For productivity applications, custom NER categories like TASK, PROJECT, DEADLINE, and MEETING are essential for extracting actionable structure from communication.
GAIAの活用方法 Named Entity Recognition (NER)
GAIA applies NER to every processed communication to extract structured information for downstream use. Person entities are linked to contact records, date entities trigger calendar actions, task entities populate your task manager, and project entities connect to existing project context. This NER pipeline is what converts the unstructured flow of email into actionable, organized information.
