We'll look at tagging our tokens with useful information including part-of-speech tags and named entity tags. We'll also explore different types of sentence parsing to help extract the meaning of a sentence. In the demo, we'll explore how to get these things done with spaCy and how to use the library's "matchers" and other features to build simple rules-based tools.
