5.4 Highly cited publications

As already mentioned, an important criterion for evaluating the impact of scientific publications is ranking among publications published worldwide in the same year and in the same subject area. Relevant bibliographic indicators refer to publications (number or percentage of the total publications) that were ranked globally in 1%, 5%, 10%, 25% and 50% of the publications with the highest impact per year and subject area. When the percentage distribution of a country's high-profile publications approaches or exceeds the global distribution of 1%, 5%, 10%, 25% and 50%, the country is considered to be approaching or exceeding the global average, respectively.

Figure 5.4.1 shows the percentage distribution of publications in open access journals (DOAJ / Gold) with a high impact of Greece for all categories of global distribution (1%, 5%, 10%, 25% and 50%).

Figure 5.4.3 illustrates the number of highly cited open access publications in each institution category for percentile levels 1%, 5%, 10%, 25% and 50%, i.e. the open access publications attributed to the category that belong respectively to the top 1%, 5%, 10%, 25% and 50% of the most cited publications in the world. During 2014-2018, "Universities", "RC-GSRT", and "Public Hospitals" record more than 100 publications each in the 1% percentile.
