论文摘要
我们在美国大流行锁定期间在Twitter上研究食物的语言，重点关注3月15日至2020年5月15日的两个月。具体来说，我们分析了封锁期间发表的770,000条推文以及五年前五年中的同等时期，并突出了一些令人担忧的趋势。首先，我们观察到，在锁定期间，从提及健康食品到不健康食品发生了显着转变。其次，我们显示了抑郁症主题标签的点上增加的相互信息，其中与食物相关的推文在锁定过程中发布，并且在锁定期间抑郁症和不健康食品，烟草和酒精之间的关联增加。
We study the language of food on Twitter during the pandemic lockdown in the United States, focusing on the two month period of March 15 to May 15, 2020. Specifically, we analyze over770,000 tweets published during the lockdown and the equivalent period in the five previous years and highlight several worrying trends. First, we observe that during the lockdown there was a notable shift from mentions of healthy foods to unhealthy foods. Second, we show an increased pointwise mutual information of depression hashtags with food-related tweets posted during the lockdown and an increased association between depression hashtags and unhealthy foods, tobacco, and alcohol during the lockdown.
