越来越多的服务和产品的在线评论通过移动的设备而不是网站发布。我们的研究表明，通过移动的设备发布的评论比网络评论更及时、更简短、更“切中要害”、更负面。此外，更多的正面评论平均比负面评论短。我们通过分析2012年在一个领先的在线评论平台上发布的与美国25个最大市场（n= 293，945）相关的旅游产品评论得出了这些结论。从这些数据中，我们提取了同一天通过移动的设备（30，540）和通过网络界面（38，248）发布的同一产品的所有评论的匹配样本。评审员对供应商和服务的总体评分从1（极差）到5（非常好）。
Online reviews of services and products are increasingly posted via mobile devices rather than a website. Our research shows that opinions posted via mobile devices are more timely, shorter, more “to the point” and more negative than web reviews. Moreover, more positive reviews are on average shorter than negative reviews. We arrived at these conclusions by analyzing all reviews posted in 2012 on a leading online review platform for travel products relating to the 25 largest U.S. markets (n=293,945). From this data we extracted matched samples of all reviews posted via mobile devices (30,540) and via the web interface (38,248) for the same product on the same day. Reviewers gave both an overall rating for the provider and for the service on a scale of 1 (extremely poor) to 5 (extremely good).
