自然灾害Twitter数据集

Natural Hazards Twitter Dataset

Lingyu Meng, Zhijie Sasha Dong

摘要:

随着互联网的发展,社交媒体已成为发布灾害相关信息的重要渠道。分析隐藏在这些文本中的态度,被称为情感分析,对政府或救援机构提高灾害应对效率至关重要,但它尚未得到足够的重视。本文旨在填补这一空白,重点调查的态度,灾害响应和分析有针对性的救灾物资在灾害响应。本文的贡献有四个方面。首先,我们提出了几种机器学习模型,用于对与灾害相关的社交媒体数据的公众情绪进行分类。其次,我们创建了一个带有情感标签的自然灾害数据集,其中包含近50,00条关于美国不同自然灾害的Twitter数据(例如,2011年的龙卷风,2012年的飓风桑迪,2013年的一系列洪水,2016年的飓风马修,2016年的暴风雪,2017年的飓风哈维,2018年的飓风迈克尔,2018年的一系列野火,以及2019年的飓风多里安。我们正在向研究社区提供我们的数据集:https://github.com/Dong-UTIL/Natural-Hazards-Twitter-Dataset。我们希望我们的贡献将使情感分析在灾难应对的研究。第三,我们专注于提取公众态度和分析基本需求(例如,在灾害应对过程中,为公众提供食品,住房,交通和医疗用品),而不仅仅是针对研究公众对自然灾害的积极或消极态度。第四,由于不同类型的自然灾害所造成的危害程度不同,因此本研究从两个不同的维度进行研究,以全面了解公众对灾害应对的看法。

英文摘要:

With the development of the Internet, social media has become an important channel for posting disaster-related information. Analyzing attitudes hidden in these texts, known as sentiment analysis, is crucial for the government or relief agencies to improve disaster response efficiency, but it has not received sufficient attention. This paper aims to fill this gap by focusing on investigating attitudes towards disaster response and analyzing targeted relief supplies during disaster response. The contributions of this paper are fourfold. First, we propose several machine learning models for classifying public sentiment concerning disaster-related social media data. Second, we create a natural disaster dataset with sentiment labels, which contains nearly 50,00 Twitter data about different natural disasters in the United States (e.g., a tornado in 2011, a hurricane named Sandy in 2012, a series of floods in 2013, a hurricane named Matthew in 2016, a blizzard in 2016, a hurricane named Harvey in 2017, a hurricane named Michael in 2018, a series of wildfires in 2018, and a hurricane named Dorian in 2019). We are making our dataset available to the research community: https://github.com/Dong-UTIL/Natural-Hazards-Twitter-Dataset. It is our hope that our contribution will enable the study of sentiment analysis in disaster response. Third, we focus on extracting public attitudes and analyzing the essential needs (e.g., food, housing, transportation, and medical supplies) for the public during disaster response, instead of merely targeting on studying positive or negative attitudes of the public to natural disasters. Fourth, we conduct this research from two different dimensions for a comprehensive understanding of public opinion on disaster response, since disparate hazards caused by different types of natural disasters.
