Methods
To investigate any potential outliers in the world’s top 2% database of
highly cited researchers, this study uses the “Updated science-wide
author databases of standardized citation indicators” by Ioannidis,
which can be found at
https://elsevier.digitalcommonsdata.com/datasets/btchxktzyw. This
database includes standardized information on citations, career-long and
recent year impact for 22 scientific fields, and includes scientists who
are ranked at the 2% or above percentile in the sub-field. The version
5 of this database is based on a Sept 1, 2022 snapshot from Scopus
[3].
The database contains standardized information on citations, career-long
and recent year impact for 22 scientific fields. The list includes
scientists who are ranked at the 2% or above percentile in the
sub-field. The version 5 of this database is based on a Sept 1, 2022
snapshot from Scopus.
The study analyzes the database in terms of the number of papers
published, year of first publication, year of most recent publication,
number of years of publishing, number of papers per year, number of
single authored papers, h-index as of end-2021, total cites 1996-2021,
self-citation percentage, and no. cites/yr. The software MS Excel was
used to compute the statistics (min, max, median) and identify
statistical outliers.
