The H-index, a method of measuring the productivity and impact of an academic’s work, is often used as a component or metric in the ranking of higher education institutions and their staff. The h-index was developed by J.E. Hirsch, University of California in 2005.
- The h-index defined: a researcher has an h-index of 25 if 25 of their papers have been cited at least 25 times.
- The principle citation databases used are: Web of Science , Scopus and Google Scholar.
- These factors should be kept in mind when assessing the h-indices of researchers, mainly when applying for grants.
