Abstract:

Comments based on the microblogging platform have become not only a factor influencing people’s shopping behaviors, but also useful references to designers for their product improvement However, the great volume of online comments has made the designers difficult to obtain useful information to improve products directly from the users The purpose of this study is to establish a model to analyze the contribution of users on the microblogging platform, and to efficiently pick out important suggestions to product improvement Besides, this study has fundamentally theoretical and practical implications in the fields of product design and online comments

Key words: usefulness analysis, microblogging, online comment, advertisement removing
