Dimensional Ratings, Textual Reviews, and Review Helpfulness in a Multi-Dimensional Rating System: An Empirical Investigation
五、报告摘要
Recently, many online review platforms have introduced a multi-dimensional (MD) rating system that provides richer quantitative data to reduce users’ information processing effort and information uncertainty. In an MD rating system, reviewers are required to provide ratings on specific product dimensions, selected by the platform, in addition to providing a textual review. In this paper, we examine how the presence of multidimensional rating affects the provisioning of textual reviews and the consequent effect on textual review helpfulness. Specifically, we leverage four quasi-experiments in a large hotel review website and find that in the review generation stage, the presence of rating on a given dimension can increase the depth of information contained in the textual review about that specific dimension. In the review consumption stage, similar to the results of past studies, we find that the depth in the textual review of a dimension is positively related to helpfulness. More importantly, we find that such a relationship is moderated by the nature of product dimension. Specifically, we find that when a dimension is listed in dimensional ratings, the positive relationship between the dimension depth and review helpfulness is amplified for a horizontally differentiated dimension but attenuated for a vertically differentiated dimension.
