Part-of-Speech Tagging

Introduction

Labeling words in a sentence with their appropriate grammatical categories, such as nouns, verbs, adjectives, or adverbs, is known as part-of-speech (POS) tagging. This technique enables us to understand a sentence’s syntactic structure and determine a word’s meaning about other words. For instance, in the sentence “The cat sat on the mat,” the words “cat” and “mat” would be tagged as nouns, “sat” as a verb, “the” as a determiner, and “on” as a preposition. By assigning each word to a grammatical category, we ensure that we prepare our data for later analysis, such as text classification, sentiment analysis, and information retrieval. Here are some common POS tags.
