Abstract

Consumers are choosing to purchase food products from retailers through online channels rather than brick-and-mortar channels. While online reviews play a crucial role in influencing online purchases, scant work has examined how consumers write reviews for food products. We argue that the nutritional value of the food is a key aspect of product performance and apply expectation-disconfirmation theory to examine whether pre-purchase expectations about a food product's nutritional value and disconfirmation of these expectations have a significant effect on online review content and linguistic characteristics. Using text-mining approaches to analyze Amazon data, we find that pre-purchase expectations, postpurchase performance, and disconfirmation regarding nutritional value affect both review content and linguistic characteristics, including review length, diversity, readability, subjectivity, and sentiment. While research suggests that postpurchase product performance is the main influence on online review writing behavior, this research shows that the pre-purchase phase also plays a key role.

但它应该是健康的！预期和实际营养价值如何影响食品在线评论的内容和语言特征

消费者选择通过在线渠道而不是实体渠道从零售商那里购买食品。虽然在线评论在影响在线购买方面发挥着至关重要的作用，但很少有人研究消费者是如何为食品撰写评论的。我们认为食品的营养价值是产品性能的一个关键方面，并应用期望-失证理论来检验购买前对食品营养价值的期望和这些期望的失证是否对在线评论内容和语言特征有显著影响。使用文本挖掘方法分析亚马逊数据，我们发现购买前的期望、购买后的表现和对营养价值的不确认都会影响评论内容和语言特征，包括评论长度、多样性、可读性、主观性和情感。虽然研究表明，购后产品性能是影响在线评论写作行为的主要因素，但本研究表明，购前阶段也起着关键作用。
