Effectiveness of Products' Review Page Projection Using Expressions and Pictures

Abstract

In this paper, we propose a method to project products' review pages onto two-dimensional space by counting the number of evaluating expressions and the number of pictures contained in the page. We apply our method to review pages for mobile phones, and show the effectiveness of the proposed method by experimentation with human subjects. The experiments using a crossover design show the effectiveness of using the number of pictures in our products' review page projection method.
