NAMED ENTITY RECOGNISATION
Abstract
With the increase in availability of data, extraction of useful information from this data has become
most important activity across all domains. When the data is available as documents written in natural language,
information extraction becomes more challenging. Named Entity recognition (NER) is a technique used
extensively for automatic extraction of useful information from unstructured natural language document
collections. Used both, for web applications as well as stand-alone systems, NER is considered as one of the
major step in Natural Language Processing (NLP) for analysis of text. This paper discusses basics of NER,
various algorithms used for NER and major applications and challenges in the field of NER.
