科学论文首条推特的积累速度与用户类型分析

Study on the Accumulation Speed and User Type of Scientific Publications’ First Tweets

[目的/意义]科学论文的首条推特是论文在推特平台传播的起点,对论文首条推特进行分析有利于展现推特数据的积累模式与用户行为特征。[研究设计/方法]以200余万篇Web of Science论文为样本,对不同学科领域科学论文首条推特的积累速度和用户类型进行了大规模比较研究。[结论/发现]生物医学与健康科学、人文与社会科学领域的论文具有最高的推特数据覆盖率。物理学与工程学领域的论文则表现出最快的首条推特积累速度。大部分情况下,科学传播者和科研人员是最快发布首条推特的用户类型。此外,对于大部分发表了较多推特数据的论文的国家/地区而言,来自当地的推特用户很大程度上贡献了本国/地区作者发表论文的首条推特。[创新/价值]对首条推特的分析有助于从数据积累的源头理解科学论文在推特平台的传播过程。

[Purpose/Significance]The first tweets of scientific publications are the beginning of papers’ dissemination on Twitter. Analysis on the first tweets is indicative of the accumulation pattern and users’ behavior characteristics of Twitter data.[Design/Methodology]2,038,646 papers from the Web of Science have been collected as research objects, which were used to make a large-scale comparison of accumulation speed and user type of papers’ first tweets in different fields.[Findings/Conclusion]Papers in the fields of Biomedical & Health Sciences and Social Sciences & Humanities have the highest coverage percentages of Twitter data. Papers’ first tweets of Physical Sciences and Engineering have the fastest accumulation. In most cases, science communicators and researchers are mostly the fastest posters of the first tweets. For the majority of countries and regions with large number of papers’ Twitter data, Twitter users from the authors’ affiliated countries or regions have made significant contribution of posting the first tweets.[Originality/Value]The analysis on first tweets is expected to shed light on the dissemination process of scientific papers on Twitter from the perspective of data accumulation.
