h-Index
h-index developed in 2005 by Jorge Hirsch, University of
California in San Diego
Attempts to quantify productivity and apparent scientific impact
of a scientist.
“A scientist has index h if h of his/her Np papers have at least h
citations each, and the other (Np − h) papers have no more than
h citations each”.
For example, an h-index of 20 means that the researcher has 20
papers each of which has been cited 20 or more times
Calculated by Scopus, WoS, Google Scholar, but only for those
papers within the database

g-Index
g-index - distribution of citations received by a given
researcher's publications
Devised by Leo Egghe in 2006
“Given a set of articles ranked in decreasing order of the
number of citations that they received, the g-index is the
(unique) largest number such that the top g articles received
(together) at least g2 citations.”
