摘要

推特等媒体已成为当代美国人表达意见和对公众舆论做出反应的平台。气候变化是一个社会持续关注的话题。机器自动化处理有助于大数据分析，适用于分析大型推文语料库。本文使用R工具对2015年至2018年的推特语料库进行情绪计算和情绪分析，以呈现公民对气候变化话题态度的总体趋势。关键词分析发现，人们关注信息的来源；气候变化和全球变暖形成了关联。支持者对极端天气和反对者的行为表示恐惧和惊讶，而反对者则对政客制造他们没有真实感受的气候变化故事表示愤怒、厌恶和悲伤。本研究还表明，自动注释工具仍然不足，情感词汇有限，否定和讽刺的识别能力有限。

Text mining attitudes towards climate change: Emotion and sentiment analysis of the Twitter corpus

Media such as Twitter has become a platform for contemporary Americans to express their opinions and allow for reaction to public opinion. Climate change is a topic of ongoing social concern. Machine-automated processing facilitates big data analysis and is suitable for analyzing a large corpus of tweets. This paper uses R tools to conduct sentiment calculation and emotion analysis on the tweet corpus from 2015 to 2018 to present the overall tendency of citizens’ attitudes toward climate change topics. The keyword analysis finds that people focus on the message’s source; CLIMATE CHANGE and GLOBAL WARMING make an association. Supporters express FEAR and SURPRISE about extreme weather and opponents’ behavior, while opponents show ANGER, DISGUST and SADNESS about politicians manufacturing climate change stories about which they have no real feelings. This study also reveals that the automatic annotation tools are still inadequate, with limited emotion lexicon and identification of negation and sarcasm.
