Tag parts of speech using Natural

An important component of many natural language processing projects is being able to identify the grammar of a piece of text. We’ll learn how to do that with Natural’s parts of speech (POS) tagger.

There are many tags, and it's worth looking them up online (search "POS tag symbols") to become familiar with them all.

The setup of the tagger may seem a little strange, but it allows you to replace the lexicon or the rules with a different lexicon or rule set of your choice.
