This study explores the dynamics of opinion evaluation in online settings, using Amazon book reviews as a case study. It distinguishes between evaluating an opinion itself and analyzing how others perceive that opinion. The research finds that the helpfulness of a review is influenced not only by its content but also by its context within other evaluations of the same product. Innovative methods, including the examination of review plagiarism, were employed to mitigate text effects on opinion evaluation. A mathematical model was developed to align with the findings, allowing for the testing of theories from sociology and social psychology. The study also uncovers variations in opinion-evaluation behaviors across different national user groups.
