Authorship Attribution Using Small Sets of Frequent Part-of-Speech Skip-grams

Computer-supported authorship attribution provides tools for extracting stylistic features that can help verify or identify the author of text documents. In many situations finding the author of a document is very important, such as the detection of plagiarism for protecting copyrights and forensic support during criminal investigations. This paper, thus explores a novel stylistic feature with the aim of accurately characterizing an author’s work. In particular, the use of part-of-speech skip-grams and an in-house top-k sequential pattern mining algorithm are considered for the task of authorship attribution. A study using a collection of of 30 texts, written by 10 authors, consisting of 2, 615, 856 words and 99, 903 sentences, confirms that mining part-of-speech skip-grams in texts facilitates authorship inference.
