Break up language strings into parts using Natural

A part of Natural Language Processing (NLP) is processing text by “tokenizing” language strings. This means we can break up a string of text into parts by word, sentence, etc. In this lesson, we will use the natural library to tokenize a string. First, we will break the string into words using WordTokenizer, WordPunctTokenizer, and TreebankWordTokenizer. Then we will break the string into sentences using RegexpTokenizer.
