Visibility score for countries using SCOPUS Affiliation Identifier and the h-threshold approach

摘要

The h-index was first proposed by Hirsch1 to quantify the impact of the academic research output (i.e. as seen from papers published rather than from say, patents registered or products or processes transferred to industry). 'A scientist has index h if h of his/her N papers have at least h citations each, and the other (N - h) papers have fewer than h citations each', where N is the number of papers published over n years. All such reductionist measures have their limitations, but it has been this writer's impression that of all such measures the h-index is the simplest but the most robust method of evaluating performance of an academic scientist. Indeed, this is now a feature of both the Web of Science and SCOPUS.
