The h-index is a measure of the number of publications published (productivity) as well as how often they are cited (impact).
PRODUCTIVITY + IMPACT = INFLUENCE
The index was first proposed by J. E. Hirsch in 2005 and is defined as:
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.
If your h-index is 15, you have 15 papers cited 15 times or more.
If your h-index is 25, you have 25 papers cited 25 times or more.
|Paper rank||Citations||Paper rank||Citations|
Both researchers have an h-index of 4. It cannot be because they do not have 5 papers with at least 5 citations.
The h-index is easily available if you have a Researcher Profile (Researcher ID, or a Scopus Author Identifier, or a Google Scholar Profile).
