Unsupervised Decomposition of a Document into Authorial Components
Moshe Koppel, Navot Akiva, Idan Dershowitz, Nachum Dershowitz · Meeting of the Association for Computational Linguistics · 2011
We propose a novel unsupervised method for separating out distinct authorial components of a document. In particular, we show that, given a book artificially munged from two thematically similar biblical books, we can separate out the two constituent books almost perfectly. This allows us to automatically recapitulate many conclusions reached by Bible scholars over centuries of research. One of the key elements of our method is exploitation of differences in synonym choice by different authors.
