摘　　要：本文基于文本挖掘技术,将情感分析和主题建模与语料库辅助下的生态话语分析相结合,考察美国清洁能源推文的主题与立场,以揭示其蕴含的生态观。研究发现,大多数推文以积极情感为主,聚焦美国能源新政的目标、途径、影响、定位和措施五类主题,体现出用户肯定和支持的正面评价;部分推文呈消极情感,聚焦能源新政的代价、挑战、问题和阻碍四类主题,体现出用户批判和质疑的负面评价。这些推文在能源与自然关系方面反映了有益性生态观,在能源与社会关系方面反映了模糊性和破坏性生态观,在能源与国家关系方面反映了破坏性生态观。该研究可为监测美国能源政治的相关舆情提供参考。Based on text mining technology,this study combines the methods of sentiment analysis and topic modeling with ecological discourse analysis to investigate the opinions and attitudes of tweets about the clean energy policies of the United States,and hence to explore their underlying ecological values.The results indicate that there is a predominant positive sentiment in the topics regarding goals,approaches,influences,positioning,and measures of developing clean energy,suggesting supportive evaluations of Twitter users.Conversely,there is a negative sentiment in the topics regarding the costs,challenges,problems,and obstacles,suggesting critical evaluations of Twitter users.Overall,the tweets reflect three kinds of ecological values:an eco-beneficial view on the energy-nature relationship,an eco-ambivalent and an eco-destructive view on the energy-society relationship,and an eco-destructive view on the energy-country relationship.This study can provide reference for monitoring public opinions on US energy policies.
