背景：近年来，电子烟(电子烟)用户数量快速增长，特别是在青少年和青壮年中。更多的电子烟产品已经上市，包括各种品牌和口味的电子烟液体。不同的电子烟味是电子烟用户在社交媒体上频繁讨论的话题。目的：调查电子烟液在社交媒体上被提及的纵向流行程度和用户感知。方法：采用数据驱动的方法分析不同电子烟口味在社交媒体上的趋势和宏观用户情绪。根据从网上商店收集的数据，电子液体香料根据其成分被划分为不同的类别。与电子烟相关的帖子是从包括Reddit和Twitter在内的社交媒体平台上收集的，使用了与电子烟相关的关键字。使用Reddit的数据编制了2013年1月至2019年4月电子液体风味类别被提及的时间趋势。对2019年5月至8月的推特数据进行情感分析，探讨电子烟用户对每种口味类别的看法。结果：将1000多种电子烟口味分为7大类。水果和糖果是Reddit上讨论最频繁的两种电子液体口味，分别占所有与味道相关的帖子的58%和15%。我们发现，与其他口味类别相比，水果口味类别的提及总体上有稳步上升的趋势，其他口味类别随着时间的推移没有太大变化。情感分析结果显示，除饮料类和烟草类外，大多数电子液体口味类别都有显著的正面情绪。结论：调查了社交媒体上提到的热门电子液体口味的最新信息，结果表明，社交媒体上提到电子液体口味的频率和用户感知的情况不同。水果是社交媒体上讨论最多的口味类别。我们的研究为未来香料电子烟的监管提供了有价值的信息。
Background: The number of electronic cigarette (e-cigarette) users has been increasing rapidly in recent years, especially among youth and young adults. More e-cigarette products have become available, including e-liquids with various brands and flavors. Various e-liquid flavors have been frequently discussed by e-cigarette users on social media.Objective: This study aimed to examine the longitudinal prevalence of mentions of electronic cigarette liquid (e-liquid) flavors and user perceptions on social media.Methods: We applied a data-driven approach to analyze the trends and macro-level user sentiments of different e-cigarette flavors on social media. With data collected from web-based stores, e-liquid flavors were classified into categories in a flavor hierarchy based on their ingredients. The e-cigarette-related posts were collected from social media platforms, including Reddit and Twitter, using e-cigarette-related keywords. The temporal trend of mentions of e-liquid flavor categories was compiled using Reddit data from January 2013 to April 2019. Twitter data were analyzed using a sentiment analysis from May to August 2019 to explore the opinions of e-cigarette users toward each flavor category.Results: More than 1000 e-liquid flavors were classified into 7 major flavor categories. The fruit and sweets categories were the 2 most frequently discussed e-liquid flavors on Reddit, contributing to approximately 58% and 15%, respectively, of all flavor-related posts. We showed that mentions of the fruit flavor category had a steady overall upward trend compared with other flavor categories that did not show much change over time. Results from the sentiment analysis demonstrated that most e-liquid flavor categories had significant positive sentiments, except for the beverage and tobacco categories.Conclusions: The most updated information about the popular e-liquid flavors mentioned on social media was investigated, which showed that the prevalence of mentions of e-liquid flavors and user perceptions on social media were different. Fruit was the most frequently discussed flavor category on social media. Our study provides valuable information for future regulation of flavored e-cigarettes.
