Part of Speech Tagging

Part of Speech (POS) is a way to describe the grammatical function of a word. In Natural Language Processing (NLP), POS is an essential building block of language models and interpreting text. While POS tags are used in higher-level functions of NLP, it's important to understand them on their own, and it's possible to leverage them for useful purposes in your text analysis. There are eight (sometimes nine) different parts of speech in English that are commonly defined. Noun: A noun is the name of a person, place, thing, or idea.
