美国商户YELP数据

互联网的迅猛发展深刻地改变着人们的生活方式，其中尤为显著的就是对消费者行为的影响。消费者不再仅仅依赖于个人经验和店家的介绍作出选择，而是通过互联网平台获取大量的第三方评价和信息。一家店的好评与否，往往不是取决于店家的自我宣传，而是来自于消费者的真实反馈。由此，互联网的评价体系成为了一种新的、具有广泛影响力的消费指南。  CnOpenData整理了YELP的美国商户线上点评数据，包含商户信息表、用户评论表、用户信息表、用户签到表、小费信息表，各表之间以商户id、用户id作为串联项，建立起丰富的互联网消费信息网络，为相关研究助力。

The rapid development of the Internet has profoundly transformed people's lifestyles, most notably its impact on consumer behavior. Consumers no longer solely rely on personal experience and merchant recommendations when making purchasing decisions; instead, they access a vast volume of third-party reviews and information via Internet platforms. Whether a business receives positive reviews often depends not on the merchant's self-promotion, but on genuine feedback from consumers. Consequently, Internet review systems have evolved into a new, widely influential consumption guide. CnOpenData has compiled online review data of US merchants from Yelp. This dataset comprises five tables: Merchant Information Table, User Review Table, User Information Table, User Check-in Table, and Tip Information Table. All tables are interconnected using merchant ID and user ID as relational keys, establishing a comprehensive Internet consumption information network that facilitates relevant research.
