Named Entity Recognition (NER)

Concept and definition

Named Entity Recognition (NER)

What is Named Entity Recognition (NER)?

Named Entity Recognition (NER) is a Natural Language Processing (NLP) technique that consists of identifying and classifying named entities in a text.

Named entities can be any real-world object that has a name of its own, such as people, organisations, locations, dates, times, currencies, among others.

The goal of NER is to identify these entities in a text and classify them into different categories, which can be useful in applications such as sentiment analysis, information extraction, text summarisation, among others.

NER is based on machine learning algorithms that analyse the linguistic features of a text to identify patterns and make decisions about the presence and classification of named entities in it.
