Ironically, I was playing with parts-of-speech (POS) analysis the other day. 
Using a pseudo-random sample of texts, I found there to be surprisingly similar POS usage between texts. With such similarity, I thought it would be difficult to use general POS as a means for ranking or sorting. On the other hand, specific POS may be useful. For example, Thoreau was dominated by first-person male pronouns but Austen was dominated by second person female pronouns.
I think there is something to be explored here.
