摘要

浆果、鳄梨、藜麦和生姜有什么共同之处?这些食物通常被视为超级食物,这是一个夸大单一食物对人的健康和幸福的重要性的营销术语。在本文中,我们着手调查所谓的超级食品是如何在网络新闻的话语中表现出来的。我们使用计算语言模型来提取用于讨论超级食品的独特主题和术语。我们的研究结果表明,新闻报道主要是关于超级食品的治疗特性的许多具体声明。结构主题模型进一步表明,提到超级食品的文章更有可能包括以下主题:a)在同一背景下的营养、外观和健康;b)零售策略;c)关于超级食品健康益处的科学研究。这些结果说明了新闻媒体对超级食品的复杂表述。

Computational Analysis of Superfood Representations in News Media
What do berries, avocado, quinoa, and ginger have in common? These food items are often regarded as superfoods, a marketing term that overstates the importance of single food items for one’s health and wellbeing. In the present paper, we set out to investigate how purported superfoods are represented in the discourse of online news. We use computational language models to extract the unique topics and terms used to discuss superfoods. Our results show that news coverage is dominated by many specific claims about the healing properties of superfoods. The structural topic model further demonstrates that articles mentioning superfoods are more likely to include topics about a) nutrients, physical appearance, and health in the same context, b) retail strategies, and c) scientific research about the health benefits of superfoods. These results illustrate complex representations of superfoods in news media.
