基于社交媒体数据的社区危机活动关注度行为研究：以2023年加拿大野火影响纽约市为例
Community-based Behavioral Understanding of Crisis Activity Concerns using Social Media Data: A Study on the 2023 Canadian Wildfires in New York City
AI总结：
本研究利用纽约市2023年6月加拿大野火烟雾事件期间的带地理标签Twitter数据，通过文本分类和社区推断模型，揭示不同性别、种族及收入群体在疏散、通勤等危机活动关注度上的差异，为应急沟通和响应提供参考。
摘要：
2023年6月，由于加拿大野火烟雾飘入，纽约市（NYC）在全球空气质量最差城市排名中位居榜首。这一前所未有的情况导致了严重的出行中断，并改变了纽约市居民的传统活动模式。本研究利用大规模社交媒体数据，考察在2023年加拿大野火烟雾影响纽约市期间，不同危机活动关注度（如疏散、居家、购物及娱乐活动等）的表现。为此，研究检索并分析了2023年6月2日至6月9日期间纽约市带有地理标签的Twitter数据。推文采用先进的文本分类技术进行处理，随后与美国社会保障管理局数据、人口普查及美国社区调查等国家数据库进行整合。最后，开发了一个模型，用于在重大野火事件中对不同活动关注度进行社区推断。研究结果表明，在野火期间，女性较少参与关于疏散、医疗出行、社交或娱乐出行以及通勤上班的讨论，这可能受到工作场所在空气质量不佳情况下仍维持运营的影响。讨论中也存在种族差异：亚裔比西班牙裔更倾向于讨论疏散和工作通勤，而非裔美国人则较少讨论社交和娱乐活动。此外，来自低收入社区和非高等教育背景的学生对疏散的关注度较低。本研究为政策制定者、应急规划人员和公共卫生官员提供了宝贵见解，有助于制定有针对性的沟通策略和公平的应急响应计划。
英文摘要：
New York City (NYC) topped the global chart for the worst air pollution in June 2023, owing to the wildfire smoke drifting in from Canada. This unprecedented situation caused significant travel disruptions and shifts in traditional activity patterns of NYC residents. This study utilized large-scale social media data to study different crisis activity concerns (i.e., evacuation, staying indoors, shopping, and recreational activities among others) in the emergence of the 2023 Canadian wildfire smoke in NYC. In this regard, one week (June 02 through June 09, 2023) geotagged Twitter data from NYC were retrieved and used in the analysis. The tweets were processed using advanced text classification techniques and later integrated with national databases such as Social Security Administration data, Census, and American Community Survey. Finally, a model has been developed to make community inferences of different activity concerns in a major wildfire. The findings suggest, during wildfires, females are less likely to engage in discussions about evacuation, trips for medical, social, or recreational purposes, and commuting for work, likely influenced by workplaces maintaining operations despite poor air quality. There were also racial disparities in these discussions, with Asians being more likely than Hispanics to discuss evacuation and work commute, and African Americans being less likely to discuss social and recreational activities. Additionally, individuals from low-income neighborhoods and non-higher education students expressed fewer concerns about evacuation. This study provides valuable insights for policymakers, emergency planners, and public health officials, aiding them in formulating targeted communication strategies and equitable emergency response plans.
