To begin with, there is an [n-gram](https://en.wikipedia.org/wiki/N-gram) bar chart built from all of the given president's addresses. An n-gram is a contiguous sequence of n items from a given sample of text or speech. Because written and spoken speech is littered with so-called "stop words" such as "and", "the", and "but", they've been removed to provide a more rich (albeit sometimes more difficult to read) view of the text. The slider only goes up to 4-grams because the data is sparse beyond that. I personally found the n-grams from our last three presidents to be less than inspiring and full of platitudes. Earlier presidents have more interesting n-grams. Next up is a word cloud of the lemmatized text from the president's addresses. [Lemmatization](https://en.wikipedia.org/wiki/Lemmatization) is the process of grouping together the inflected forms of a word so they can be analyzed as a single item. Think of this as a more advanced version of [stemming](https://en.wikipedia.org/wiki/Stemming) where we can establish novel links between words like "better" and "good" that might otherwise be overlooked in stemming.
