公众对气候变化的看法传统上通过调查来衡量。然而，社交网络的爆炸式普及为研究与自然和/或社会经济事件相关的公共话语的时空模式提供了新的机会。在社交网络中，Twitter是最大的微博客服务之一。Twitter的架构提出了一个问题：“发生了什么？”“信息交流的基石。这启发了将Twitter用户用作分布式传感器的概念，该概念已成功应用于自然科学和社会科学。在2012年和2013年，我们收集了180万条关于“气候变化”和“全球变暖”的推文，这些推文使用五种主要语言（英语、德语、俄语、葡萄牙语和西班牙语）。我们讨论了推特的地理分布，每周和每日的模式，影响气候变化推特的主要新闻事件，随着时间的推移，最权威的传统媒体，博客，以及不同国家的推特用户引用的最权威的气候变化信息组织来源。我们预计，社交网络挖掘将成为公众讨论气候变化的主要数据来源。(C)2014爱思唯尔有限公司版权所有。
Public perceptions of climate change are traditionally measured through surveys. The exploding popularity of social networks, however, presents a new opportunity to research the spatiotemporal pattern of public discourse in relation to natural and/or socio-economic events. Among the social networks, Twitter is one of the largest microblogging services. The architecture of Twitter makes the question "what's happening?" the cornerstone of information exchange. This inspired the notion of using Twitter users as distributed sensors, which has been successfully employed in both the natural and social sciences. In 2012 and 2013, we collected 1.8 million tweets on "climate change" and "global warming" in five major languages (English, German, Russian, Portuguese, and Spanish). We discuss the geography of tweeting, weekly and daily patterns, major news events that affected tweeting on climate change, changes in the central topics of discussion over time, the most authoritative traditional media, blogging, and the most authoritative organizational sources of information on climate change referenced by Twitter users in different countries. We anticipate that social network mining will become a major source of data in the public discourse on climate change. (C) 2014 Elsevier Ltd. All rights reserved.
