近年来，电子烟(电子烟)市场增长迅速。然而，电子烟使用者相关症状的原因及其对健康的影响仍不确定。这项研究旨在利用从Reddit收集的用户生成数据，挖掘症状与电子液体成分之间的潜在关系，如丙二醇(PG)、蔬菜甘油(VG)、香料提取物和尼古丁。从Reddit上收集了2011年1月1日至2015年6月30日期间与e-Liquid相关的帖子共3605篇。分析了VG/PG在不同风味中的分布规律。接下来，研究了电子烟使用的典型症状--喉咙撞击与电子烟液体成分之间的关系。最后，根据e-iquid组件和用户情绪检查了其他症状。我们发现了三组主要的发现：1)我们根据VG/PG比率确定了三组风味。水果、奶油和坚果的味道相似。甜味、薄荷味和调味品被归为一类。烟草和饮料口味是第三类。2)喉咙刺痛的分析发现，薄荷醇和烟草的味道，以及PG和尼古丁水平的高比例，可以产生更多的喉咙刺痛。3)共识别和分析了9个系统的25个症状。VG/PG比值、风味和尼古丁等成分可能是导致这些症状的原因。与电子烟使用症状相关的电子液体成分是VG/PG比率、味道和尼古丁水平。可以根据本研究构建的电子液体组件类别的结构进行未来的分析。这项研究中揭示的信息可以被电子烟用户用来了解电子烟液体类型与症状之间的关系，被供应商用来选择适当的电子液体配方，并被政策制定者用来制定新的法规。
The electronic cigarette (e-cigarette) market has grown rapidly in recent years. However, causes of e-cigarette related symptoms among users and their impact on health remain uncertain. This research aims to mine the potential relationships between symptoms and e-liquid components, such as propylene glycol (PG), vegetable glycerine (VG), flavor extracts, and nicotine, using user-generated data collected from Reddit. A total of 3605 e-liquid related posts from January 1st, 2011 to June 30th, 2015 were collected from Reddit. Then the patterns of VG/PG distribution among different flavors were analyzed. Next, the relationship between throat hit, which was a typical symptom of e-cigarette use, and e-liquid components was studied. Finally, other symptoms were examined based on e-liquid components and user sentiment. We discovered 3 main sets of findings: 1) We identified three groups of flavors in terms of VG/PG ratios. Fruits, cream, and nuts flavors were similar. Sweet, menthol, and seasonings flavors were classified into one group. Tobacco and beverages flavors were the third group. 2) Throat hit was analyzed and we found that menthol and tobacco flavors, as well as high ratios of PG and nicotine level, could produce more throat hit. 3) A total of 9 systems of 25 symptoms were identified and analyzed. Components including VG/PG ratio, flavor, and nicotine could be possible reasons for these symptoms. E-liquid components shown to be associated with e-cigarette use symptomology were VG/PG ratios, flavors, and nicotine levels. Future analysis could be conducted based on the structure of e-liquid components categories built in this study. Information revealed in this study could be utilized by e-cigarette users to understand the relationship between e-liquid type and symptoms experienced, by vendors to choose appropriate recipes of e-liquid, and by policy makers to develop new regulations.
