The POS tagging process is the process of finding the sequence of tags which is most likely to have generated a given word sequence. We can model this POS process by using a Hidden Markov Model (HMM), where tags are the hidden states that produced the observable output, i.e., the words.
Why POS Tagging is important?
Part of Speech (hereby referred to as POS) Tags are useful for building parse trees, which are used in building NERs (most named entities are Nouns) and extracting relations between words. POS Tagging is also essential for building lemmatizers which are used to reduce a word to its root form.

How to use naivebayesclassifier for sentiment in Python?
First, you begin with a test sentence: >>> test_sentence = “This is the best band I’ve ever heard!” Then, you tokenize the sentence and figure out which words the sentence shares with all_words. These constitute the sentence’s features.
How are the POS represented in text processing?
In text processing, those POS (or word classes) are usually represented as their abbreviation and we call it tag. For example if we use nltk, it uses The Penn Treebank tagset as a default. https://www.ling.upenn.edu/courses/Fall_2003/ling001/penn_treebank_pos.html
