Understanding effects of personalized vs. Gediminas Adomavicius, Jesse Bockstedt, Shawn P.Furthermore, persuasion cascades notably exist, but the average scoring rule has a small product quality estimation error under practical scenarios. Experiment results show that our inference algorithm has a high accuracy. We conduct experiments on both synthetic data and real-world data from Amazon and TripAdvisor. We also design a maximum likelihood algorithm to infer parameters of the persuasion cascade. We further bound the product quality estimation error for a class of rating aggregation rules including the averaging scoring rule, via the matrix perturbation theory and the Chernoff bound. We formulate a high-order Markov chain to characterize the opinion dynamics of a persuasion cascade and prove the convergence of opinions. We first develop a mathematical model to capture key factors of a persuasion cascade.

(1) How does the persuasion cascade influence the product quality estimation accuracy? (2) Given a real-world product rating dataset, how to infer the persuasion cascade and analyze it to draw practical insights? However, a well-known psychological phenomenon called “ message-based persuasion” lead to “ biased” product ratings in a cascading manner (we call this the persuasion cascade). One functionality of such systems is to uncover the product quality via product ratings (or reviews) contributed by consumers. Online product rating systems have become an indispensable component for numerous web services such as Amazon, eBay, Google Play Store, and TripAdvisor.
