Finding Characteristic Features in Stylometric Analysis

The usual focus in authorship studies is on authorship attribution, i.e. determining which author (of a given set) wrote a piece of unknown provenance. The usual setting involves a small number of candidate authors, which means that the focus quickly revolves around a search for features that discriminate among the candidates. Whether the features that serve to discriminate among the authors are characteristic is then not of primary importance. We respectfully suggest an alternative in this paper, namely a focus on seeking features that are characteristic for an author with respect to others. To determine an author’s characteristic features, we first seek elements that he or she uses consistently, which we therefore regard as representative, but we likewise seek elements which the author uses distinctively in comparison to an opposing author. We test the idea on a task recently proposed that compares Charles Dickens to both Wilkie Collins and a larger reference set comprising several authors’ works from the 18 and 19 century. We then compare the use of representative and distinctive features to Burrows’ Delta and Hoovers’ CoV Tuning; we find that our method bears little similarity with either method in terms of characteristic feature
