Lexomic Analysis of Medieval Latin Texts

In this paper we demonstrate how “lexomic” methods of computer-assisted statistical analysis can be adapted to the investigation of the structures, styles, sources, and authorship of Medieval Latin texts. The methods, which compare the vocabulary distributions of segments of texts, are first shown to produce results consistent with “control” texts whose characteristics have been determined by more traditional approaches.
