The Use of Horizontal Visibility Graphs to Identify the Words that Define the Informational Structure of a Text

Abstract

A compactified horizontal visibility graph for the language network and identification of the words that define the informational structure of a text is proposed. It was found that the networks constructed in such a way are scale free, and have a property that among the nodes with largest degrees there are words that determine not only communicative text structure, but also its informational structure.
