An analysis of review content and reviewer variables that contribute to review helpfulness

Review helpfulness is attracting increasing attention of practitioners and academics. It helps in reducing risks and uncertainty faced by users in online shopping. This study examines uninvestigated variables by looking at not only the review characteristics but also important indicators of reviewers. Several significant review content and two reviewer variables are proposed and an effective review helpfulness prediction model is built using stochastic gradient boosting learning method. This study derived a mechanism to extract novel review content variables from review text. Six popular machine learning models and three real-life Amazon review data sets are used for analysis. Our results are robust to several product categories and along three Amazon review data sets. The results show that review content variables deliver the best performance as compared to the reviewer and state-of-the-art baseline as a standalone model. This study finds that reviewer helpfulness per day and syllables in review text strongly relates to review helpfulness. Moreover, the number of space, aux verb, drives words in review text and productivity score of a reviewer are also effective predictors of review helpfulness. The findings will help customers to write better reviews, help retailers to manage their websites intelligently and aid customers in their product purchasing decisions.

Reactivity without legitimacy? Online consumer reviews in the restaurant industry

In recent years, web sites where individual consumers can rate and review goods and services have mushroomed all over the Internet. Restaurants are particularly affected by online reviewing. If the impact of online consumer reviews (OCRs) on the demand side of markets is now well understood and measured, few studies examine the reception of this new evaluation method by those who are assessed. Based on interviews with French restaurant managers, our research shows that OCRs systems reconfigure relations of accountability in the restaurant industry. We use the notion of reactivity to describe the mechanisms through which the new evaluation system transforms the activity of restaurants. We also examine the affects surrounding the reception of ratings and reviews by restaurant managers and the moral criteria that accompany their discourses on online reviews. Many restaurants consider online reviews as a brutal and hypocritical mode of judgment. The judgment produced by online ratings and reviews is not easily borne by restaurant managers, because it challenges the conventions of quality they had previously internalized as legitimate, that is, those produced by professional experts. We interpret this ambivalent reception as the unfinished movement of transforming a performative reputation device into a legitimate evaluation institution.

文化冲突与文化尴尬－《刮痧》与当下中国影视走向三人谈

以许大同为代表的几乎所有的在美华人，试图在所面临着的西主化的冲击下改变自己，将自己融入到它们中间，彻底改变自己的第三世界的身份。第三世界的许大同们心甘情愿地接受着第一世界化的挤压。像《刮痧》这样的电影正处于中国影视走向世界的第二步，它们不像第一阶段的影片那样，向西方所展现的那种“中国特色”或“东方化”还往往停留在物质层面，精神上的揭示也是停留在展示给西方人看的立场上。到《先刮痧》，这种简单的线形判断没有了，化批判虽然淡了，但是编导对于东西方化冲突的理解加深了，那种冲突的复杂和转化体现了各种化自身的力量。
