Product reviews posted at online shopping sites vary greatly in quality. This paper ad- dresses the problem of detecting low- quality product reviews. Three types of bi- ases in the existing evaluation standard of product reviews are discovered. To assess the quality of product reviews, a set of spe- cifications for judging the quality of re- views is first defined. A classification- based approach is proposed to detect the low-quality reviews. We apply the pro- posed approach to enhance opinion sum- marization in a two-stage framework. Ex- perimental results show that the proposed approach effectively (1) discriminates low- quality reviews from high-quality ones and (2) enhances the task of opinion summari- zation by detecting and filtering low- quality reviews.
