This post is a followup to A Novel Method for Detecting Plot posted June 15, 2014.
For the past few years, I have been exploring the relationship between sentiment and plot shape in fiction. Earlier today I posted an R package titled “syuzhet” to github. The package is designed to extract sentiment and plot information from prose. Methods for text import, sentiment extraction, and plot arc modeling are described in the documentation and in the package vignette. What follows below is a blog-friendly version of a longer academic paper describing how I employed this package to study plot in a corpus of ~50,000 novels.
