Abstract

Text cohesion is an important element of discourse
processing. This paper presents a new approach to modeling,
quantifying, and visualizing text cohesion using automated
cohesion flow indices that capture semantic links among
paragraphs. Cohesion flow is calculated by applying
Cohesion Network Analysis, a combination of semantic
distances, Latent Semantic Analysis, and Latent Dirichlet
Allocation, as well as Social Network Analysis. Experiments
performed on 315 timed essays indicated that cohesion flow
indices are significantly correlated with human ratings of text
coherence and essay quality. Visualizations of the global
cohesion indices are also included to support a more facile
understanding of how cohesion flow impacts coherence in
terms of semantic dependencies between paragraphs.
