What is Named Entity Recognition (NER)?
A basic practice in natural language processing (NLP), particularly under the umbrella of Natural Language Understanding (NLU), is extracting and identifying specific entities from text.
Named Entity Recognition (NER) is the action of locating particular entities in a text such as names of people, companies, places, and some dates, termed as ‘named entities.’ For instance, “Microsoft” being a company is identified by NER and so is “Seattle” as a location. Such attributes greatly enhance information processing across various industries.
Transforming text into actionable insights is one of the perks associated with named entity recognition meaning. Using machine learning models, NER identifies entity boundaries and assigns context-based labels. Sophisticated training helps mitigate issues such as distinguishing “Apple” as a company or fruit.
