Webometrics released their January data on university rankings around the world, with the National and Kapodistrian University of Athens ranked 74th in the world and 11th in Europe based on "Top Universities by Top Google Scholar Citations".
This ranking is compiled based on the number of citations of the research work of the professors and researchers of the institutions, a number that is identified through the most popular academic bibliography search engine, GoogleScholar. Citation data for this ranking were collected during the 10-day period of 10-20 January 2020.
The National and Kapodistrian University of Athens achieved that ranking due to its high citation record which was 2,039,623.
Therefore, the number of citations and the ranking of each university is calculated by the sum of citations of the first 110 profiles of university professors and researchers minus the citations of the first ten profiles.
As the National and Kapodistrian University of Athens noted, it is "particularly striking" that its number of cross-references covers 33 percent of all thirty-four Greek universities included in the ranking.
