Online reviews provide users with the opportunity to rate various types of items such as movies, music, and video games using a combination of numeric scores and textual comments. The study proposes a novel method that combines network modeling with statistical matching to estimate the unbiased association between words and hyper-polarized items in online reviews. The application of this method to a sample of 40,665 items from the website Metacritic detects 218 hyper-polarized items; these are matched with an equal number of items using 8 covariates of item quality and network centrality. Application of the method reveals an unbiased association between hyper-polarization and semantics indicating reactive social action in online reviews, especially related to controversial political issues in the USA.

Abstract
Online reviews provide users with the opportunity to rate various types of items such as movies, music, and video games using a combination of numeric scores and textual comments. The study proposes a novel method that combines network modeling with statistical matching to estimate the unbiased association between words and hyper-polarized items in online reviews. The application of this method to a sample of 40,665 items from the website Metacritic detects 218 hyper-polarized items; these are matched with an equal number of items using 8 covariates of item quality and network centrality. Application of the method reveals an unbiased association between hyper-polarization and semantics indicating reactive social action in online reviews, especially related to controversial political issues in the USA.File | Dimensione | Formato | |
