阿拉斯加处于气候变化的最前沿，面临着包括能源消耗在内的重大挑战。了解阿拉斯加人对能源消耗的看法和意见对于解决阿拉斯加国内的能源问题和创造可持续的未来是很重要的。然而，使用传统的调查方法来收集公众对能源消耗的意见是具有挑战性的，这些方法通常是昂贵的，劳动密集型的，而且速度慢。这项研究利用信息丰富的Twitter数据来调查阿拉斯加人对各种能源，特别是清洁能源的看法和意见。利用2014年至2016年在阿拉斯加收集的地理标记Twitter数据，首先采用基于词典的情感分析方法来分析所表达意见的极性。此外，采用一种新颖的基于模糊的理论来推导每条推文的观点情绪。结果表明，一组与能源相关的关键词，如“太阳”、“电力”和“核能”，有一个有价值的增长率。在与可再生能源相关的20个关键词中，排名最高的是“潮汐”，其次是“太阳能电池板”。此外，阿拉斯加人对各种能源的关注正在急剧增加。重要的是，从2014年到2016年，阿拉斯加人对能源和可再生能源的态度发生了积极的变化，这表明阿拉斯加人在未来的能源选择中更容易接受甚至支持可再生能源。
Alaska is at the forefront of climate change and subject to salient challenges including energy consumption. It is important to understand Alaskans' perceptions and opinions about energy consumption to solve Alaska's domestic energy problems and creating a sustainable future. However, it is challenging to collect public opinions about energy consumption using conventional survey methods, which are often expensive, labor-intensive, and slow. This study utilizes information-rich Twitter data to investigate Alaskans' perceptions and opinions on various energy sources and in particular clean energy sources. Using the geotagged Twitter data collected in Alaska from 2014 to 2016, a lexicon-based sentiment analysis approach was first applied to analyze the polarity in the expressed opinions. Further, a novel fuzzy-based theory is employed to derive the sentiment of the opinion in each tweet. The results indicate that there is a valuable growth rate for a set of energy-related keywords, such as "sun", "power", and "nuclear". The rank of top 20 renewable energy-related keywords shows the word "Tidal" has the highest ranking followed by "solar panel". Moreover, the attention to various types of energy is increasing dramatically among Alaskans. Importantly, Alaskans' attitudes toward energy and renewable energy changed positively from 2014 to 2016, indicating that Alaskans' energy choices are more acceptive towards or even favor renewable energy in the future.
