Abstract:
A named entity (NE) denotes a noun or noun phrase referring to a name belonging to a
predefined category like person, location and organization. The task of identifying and
categorizing named entities from text is known as named entity recognition (NER). NEs
are often the pivotal as well as the most information-bearing elements of a text, and NER
systems find application in a number of tasks like information extraction, text mining
and machine translation.
