The Online Text Comparator is similar to Amazon's Statistically Improbable Phrases. It identifies statistically improbable
words--words that appear significantly more frequently in the first text compared to the second and also those that appear significantly less frequently.
For example, let's say the first text was Moby Dick and the second, a large corpus of English. The word whale would be a statistically
improbable word.
