What does h-Index mean?
Answer
H-index is an author-level metric that indicates research output. It reflects both the number of publications (productivity) and the distribution of citations to those publications (impact). The indicator is calculated in author profiles by citations databases such as Google Scholar, Scopus or Web of Science.
A h-index of x for an author signifies that the author has published at least x articles, each of which has been cited at least x times.
A h-index of 5 for an author signifies that the author has published at least 5 articles, each of which has been cited at least 5 times.
