In this paper we seek to examine the co-authoring pattern of a select group of researchers that are affiliated with a specific country. By way of making use of standard bibliometric analysis, we explore the publication evolution of all COVID-19-related peer reviewed papers that have been (co)-authored by researchers that are affiliated with Greek institutions. The aim is to identify its advancement over time, the institutions involved and the countries with which the co-authors are affiliated with. The timeframe of the study spans from the moment that WHO Director-General declared the novel coronavirus outbreak a public health emergency of international concern (WHO, 2020.

Accessed on 10 May 2020., Archived: WHO timeline-covid-19), January 2020, to October 2020. Findings indicate that there is a steady increase in the number of publications as well as the number of scientific collaborations over time. At a cross-country level, results suggest that the affiliated institutional sectors such as the Higher Education Sector (HES) and the Government Sector (GOV) contributed the most in terms of scientific output. On an international scale, the evolution of the scientific collaboration is imprinted and distributed as a chain of affiliations that linked nations together. Such chains are represented as clusters of countries, in which the scientific connections between different countries can be visualised. It can be reasoned that a significant amount of publications (20%) is affiliated with countries having “traditionally” major scientific impact on the field of Medicine.

在本文中，我们试图检查隶属于特定国家的一组选定研究人员的合着模式。通过使用标准的文献计量分析，我们探索了所有与希腊机构有关联的研究人员（共同）撰写的与 COVID-19 相关的同行评审论文的出版演变。目的是确定其随着时间的推移、所涉及的机构以及共同作者所属的国家的进步。该研究的时间跨度自世卫组织总干事宣布新型冠状病毒爆发为国际关注的突发公共卫生事件之时起（世卫组织，2020 年。存档：世卫组织时间线-covid-19。检索自存档：世卫组织时间线-COVID-19 . https://www.who.int/news/item/27-04-2020-who-timeline---covid-19。2020 年 5 月 10 日访问。存档：世卫组织时间线-covid-19），2020 年 1 月至 2020 年 10 月。调查结果表明，随着时间的推移，出版物数量和科学合作数量稳步增加。在跨国层面，结果表明高等教育部门（HES）和政府部门（GOV）等附属机构部门在科学产出方面的贡献最大。在国际范围内，科学合作的演变被印记并分布为将国家联系在一起的一系列从属关系。这样的链条被表示为国家集群，其中不同国家之间的科学联系可以被可视化。
