As the COVID-19 pandemic unfolds, researchers from all disciplines are coming together and contributing their expertise. CORD-19, a dataset of COVID-19 and coronavirus publications, has been made available alongside calls to help mine the information it contains and to create tools to search it more effectively. We analyse the delineation of the publications included in CORD-19 from a scientometric perspective. Based on a comparison to the Web of Science database, we find that CORD-19 provides an almost complete coverage of research on COVID-19 and coronaviruses. CORD-19 contains not only research that deals directly with COVID-19 and coronaviruses, but also research on viruses in general. Publications from CORD-19 focus mostly on a few well-defined research areas, in particular: coronaviruses (primarily SARS-CoV, MERS-CoV and SARS-CoV-2); public health and viral epidemics; molecular biology of viruses; influenza and other families of viruses; immunology and antivirals; clinical medicine. CORD-19 publications that appeared in 2020, especially editorials and letters, are disproportionately popular on social media. While we fully endorse the CORD-19 initiative, it is important to be aware that CORD-19 extends beyond research on COVID-19 and coronaviruses.

CORD-19的科学计量概述

随着COVID-19大流行的发展，各学科的研究人员聚集在一起并贡献自己的专业知识。CORD-19是COVID-19和冠状病毒出版物的数据集，已经与电话一起提供，以帮助挖掘其中包含的信息并创建工具以更有效地进行搜索。我们从科学的角度分析了CORD-19中包含的出版物的描述。根据与Web of Science数据库的比较，我们发现CORD-19提供了关于COVID-19和冠状病毒的几乎完整的研究范围。CORD-19不仅包含直接研究COVID-19和冠状病毒的研究，而且还涉及一般的病毒研究。CORD-19的出版物主要集中在几个定义明确的研究领域，特别是：冠状病毒（主要是SARS-CoV，MERS-CoV和SARS-CoV-2）；公共卫生和病毒流行病；病毒的分子生物学；流感和其他病毒家族；免疫学和抗病毒药；临床医学。2020年出现的CORD-19出版物，特别是社论和信函，在社交媒体上的受欢迎程度尤其高。尽管我们完全赞同CORD-19倡议，但重要的是要意识到，CORD-19的范围不限于对COVID-19和冠状病毒的研究。
