A “Citation Surplus” Should Be Added to the h-IndexDOI: 10.4236/oalib.1103959, PP. 1-5 Subject Areas: Statistics Keywords: h-Index, Scientific Productivity, Scientometrics, Pareto-Efficiency Abstract
The h-index is the largest number h such that h publications have at
least h citations. The index reflects
both the number of publications and the number of citations per publication. One
unperceived deficiency of this metric is that it is Pareto-inefficient. A
“citation surplus” would be absent and, thus, the h-index would be efficient for a researcher if all his h papers that are equal or above his h-index received exactly h citations. This inefficiency would not
be of great concern if those h papers
were normally distributed. However, the rank from top to bottom does not decay
exponentially. The decay follows the power law known in the literature as
Lotka’s law. To remedy this deficiency, I suggest the h-index be supplemented by a researcher’s citation surplus.
