论文摘要
信息和通信技术已使名称共享经济的现象的兴起，该现象代表了通过在线平台协调的人们之间的活动，以获取，提供或共享对商品和服务的访问。在主持共享经济的服务时，通常在主机和来宾之间进行个人联系是很常见的，这可能会影响用户做出负面评论的决定，因为负面评论会损害所提供的服务。为了评估这个问题，我们收集了来自两个共享经济平台Airbnb和Couchsurfing的评论，以及一个主要与酒店（传统经济），Booking.com合作的平台，用于巴西和美国的某些城市。低谷分析，我们发现共享经济的评论往往比传统经济中的评论更为积极。这可以代表这些系统中的问题，因为本研究中对志愿者进行的实验表明。此外，我们讨论了如何利用获得的结果来帮助改善用户的决策。
Information and communications technologies have enabled the rise of the phenomenon named sharing economy, which represents activities between people, coordinated by online platforms, to obtain, provide, or share access to goods and services. In hosting services of the sharing economy, it is common to have a personal contact between the host and guest, and this may affect users' decision to do negative reviews, as negative reviews can damage the offered services. To evaluate this issue, we collected reviews from two sharing economy platforms, Airbnb and Couchsurfing, and from one platform that works mostly with hotels (traditional economy), Booking.com, for some cities in Brazil and the USA. Trough a sentiment analysis, we found that reviews in the sharing economy tend to be considerably more positive than those in the traditional economy. This can represent a problem in those systems, as an experiment with volunteers performed in this study suggests. In addition, we discuss how to exploit the results obtained to help improve users' decision making.
