It is a process of converting a sentence to forms – list of words, list of tuples (where each tuple is having a form (word, tag) ). It provides a simple API for diving into common natural language processing (NLP) tasks such as part-of-speech tagging, noun phrase extraction, sentiment analysis, classification, translation, and more. Back in elementary school, we have learned the differences between the various parts of speech tags such as nouns, verbs, adjectives, and adverbs. … The POS is tagged with abbreviations like NN for a noun, … VBP for verb singular present, and JJ for adjective.
