TL;DR
This paper introduces a statistical hypergeometric test to identify significantly enriched themes in storysets, demonstrated on Star Trek episodes, with implementation in an R package and web app.
Contribution
It presents a novel application of the hypergeometric test for theme enrichment analysis in stories, including a new dataset and software tools.
Findings
Hypergeometric test effectively identifies enriched themes in storysets.
Application to Star Trek episodes reveals meaningful thematic patterns.
Software tools facilitate theme analysis for storytelling datasets.
Abstract
In this paper, we describe how the hypergeometric test can be used to determine whether a given theme of interest occurs in a storyset at a frequency more than would be expected by chance. By a storyset we mean simply a list of stories defined according to a common attribute (e.g., author, movement, period). The test works roughly as follows: Given a background storyset and a sub-storyset of interest, the test determines whether a given theme is over-represented in the sub-storyset, based on comparing the proportions of stories in the sub-storyset and background storyset featuring the theme. A storyset is said to be "enriched" for a theme with respect to a particular background storyset, when the theme is identified as being significantly over-represented by the test. Furthermore, we introduce here a toy dataset consisting of 280 manually themed Star Trek television franchise episodes.…
