In learning more about text mining over the past several months, one aspect of text that I’ve been interested in is readability. A text’s readability measures how hard or easy it is for a reader to read and understand what a text is saying; it depends on how sentences are written, what words are chosen, and so forth. I first became really aware of readability scores of books through my kids’ reading tracking websites for school, but it turns out there are lots of frameworks for measuring readability.
