StyloMatrix

Mining stylometric representation for authorship analysis. This repository contains several multi-language NLP utilities for text proccessing and several models for authorship analysis. The ca.mcgill.sis.dmas.nlp.model.astyle package contains the implementation of the following models:

• Joint Topical-Lexical Modality
• Character Modality
• Syntactic Modality
• LDA, LSA
• N-grams, static features, typed N-grams
• Two baselines from PAN2016

Example runs are included in the ca.mcgill.sis.dmas.nlp.exp package. You can refer to the source code for API usage.

• PAN2014 Authorship Verification
• IMDB62 Authorship Identification
• ICWSM2012 Authorship Characterization
• PAN2013 Authorship Characterization
