Part-Of-Speech Tagging

Part-of-speech tagging (POS tagging) is the task of tagging a word in a text with its part of speech. A part of speech is a category of words with similar grammatical properties. Common English parts of speech are noun, verb, adjective, adverb, pronoun, preposition, conjunction, etc.

Example:

| Vinken | , | 61 | years | old | | --- | ---| --- | --- | --- | | NNP | , | CD | NNS | JJ |
