Data for "Comprehensive mapping of local and diaspora scientists for evaluation, planning and policy purposes: a database and analysis of 63951 Greek scientists"

Research policy and planning for a given country may benefit from reliable data on both its scientific workforce as well as the diaspora of scientists for countries with substantial brain drain. Here we use a systematic approach using Scopus to generate a comprehensive country-level database of all scientists in Greece. Moreover, we expand that database to include also Greek diaspora scientists. The database that we have compiled includes 63951 scientists who have published at least 5 papers indexed in Scopus. Of those, 35116 have an affiliation in Greece. We validate the sensitivity and specificity of the database against different control sets of scientists. We also analyze the scientific disciplines of these scientists according to the Science Metrix classification (174 subfield disciplines) and provide detailed data on each of the 63951 scientists using multiple citation indicators and a composite thereof. These analyses demonstrate differential concentrations in specific subfields for the local versus the diaspora cohorts, as well as an advantage of the diaspora cohort in terms of citation indicators especially among top-impact researchers. The approach that we have taken can be applied to map also the scientific workforce of other countries and nations for evaluation, planning and policy purposes.对于任意国家而言，其科研政策制定与规划工作均可从可靠的科研人力数据中获益；对于存在大规模人才外流现象的国家，还需纳入海外侨居科学家的相关数据。本研究采用基于斯高帕斯数据库（Scopus）的系统化方法，构建了涵盖希腊全体科研人员的国家级综合数据库。此外，我们进一步扩展该数据库，将希腊侨居海外的科研人员也纳入其中。本研究编译的数据库共包含63951名科研人员，他们均至少发表过5篇被斯高帕斯数据库收录的论文，其中35116名科研人员的任职机构位于希腊境内。我们针对多组科研人员对照样本，验证了该数据库的灵敏度与特异度。此外，我们依据科学计量（Science Metrix）分类体系（包含174个细分学科领域），对上述科研人员的科研学科进行了分析，并基于多项引用指标及其综合指标，为63951名科研人员分别提供了详细数据。这些分析结果显示，本土科研人员与侨居海外科研人员群体在特定细分学科领域的分布存在显著差异；同时，侨居海外科研人员群体在引用指标上表现更优，在高影响力研究者群体中这一优势尤为明显。本研究采用的方法可推广至其他国家的科研人力图谱绘制工作，用于科研评估、规划与政策制定。
