<head xmlns="http://www.tei-c.org/ns/1.0">Stylometric features</head> <p xmlns="http://www.tei-c.org/ns/1.0">We use word frequencies as well as character tetragrams to represent stylometric features. We tested different amounts of most frequent words and decided to work with the top 3000 (mfw3000). Additionally we use the top 1000 character tetragrams (4gram). </p>
