摘要:

本文旨在利用科学文献的社会交流,特别是推文,分析社会媒体用户对研究领域内出版物的情绪。首先,我们采用SentiStrength工具,扩展了新创建的词汇,对Altmetric.com提供的与1,083,535篇出版物相关的6,482,260条推文的情感进行分类。然后,我们提出了谐波均值为基础的统计措施,以产生一个专门的词汇,使用积极和消极的情绪得分和频率度量。接下来,我们采用一种新颖的文章级摘要方法来进行领域级情感分析,以衡量Twitter上社交媒体用户对科学文献的看法。最后,我们提出并采用基于方面的分析方法来挖掘用户的表达与文章的各个方面,如推文的标题,摘要,方法,结论,或结果部分。我们发现,研究社区表现出不同的情绪对各自的领域。对文章方面的领域分布的分析表明,在医学,经济学,商业和决策科学中,推文方面集中在结果部分。相比之下,物理学与天文学、材料科学和计算机科学这些方面则侧重于方法论部分。总体而言,本研究有助于我们了解科学共同体对科技文献的在线社会交流情感。具体而言,这种细粒度的分析可以帮助研究界改善他们关于科学文章的社交媒体交流,以有效地传播他们的科学发现,并进一步增加他们的社会影响。

英文摘要:

This article aims to exploit social exchanges on scientific literature, specifically tweets, to analyse social media users' sentiments towards publications within a research field. First, we employ the SentiStrength tool, extended with newly created lexicon terms, to classify the sentiments of 6,482,260 tweets associated with 1,083,535 publications provided by Altmetric.com. Then, we propose harmonic means-based statistical measures to generate a specialized lexicon, using positive and negative sentiment scores and frequency metrics. Next, we adopt a novel article-level summarization approach to domain-level sentiment analysis to gauge the opinion of social media users on Twitter about the scientific literature. Last, we propose and employ an aspect-based analytical approach to mine users' expressions relating to various aspects of the article, such as tweets on its title, abstract, methodology, conclusion, or results section. We show that research communities exhibit dissimilar sentiments towards their respective fields. The analysis of the field-wise distribution of article aspects shows that in Medicine, Economics, Business & Decision Sciences, tweet aspects are focused on the results section. In contrast, Physics & Astronomy, Materials Sciences, and Computer Science these aspects are focused on the methodology section. Overall, the study helps us to understand the sentiments of online social exchanges of the scientific community on scientific literature. Specifically, such a fine-grained analysis may help research communities in improving their social media exchanges about the scientific articles to disseminate their scientific findings effectively and to further increase their societal impact.
