Statistical stylometry is the new literary critic.

Computer scientists at Stony Brook University in New York may have just put literary critics out of a job. The team developed a software program that predicts the likelihood of a book becoming a commercial success with 84% accuracy.

The predictive algorithm uses statistical stylometry, which mathematically assesses patterns and usage of grammar and vocabulary in books. The process analyzed thousands of downloadable books available in the Project Gutenberg archives, along with data from Amazon sales and national awards like the Pulitzer Prize. The study included books of every genre, from adventure and romance to science fiction and poetry, and determined that certain elements of writing style significantly contribute to the commercial success of a book.
