The h- index is calculated based on the set of the scientists’ most cited papers and the number of citations that they have received in other publications.
The h-index can be calculated manually as follows:
- Search the desired author’s name
- Order the list of author’s publications from the largest to the lowest value by the number of citations these publications received.
- Compare the number of publications and the number of citations to the extent that the number of citations is equal to or more than the publications
- The acquired result indicates the h-index. It should be mentioned that the accurate calculation of the h-index depends on the comprehensiveness of the target database.
The most important databases for calculating h-index are:
- Google Scholar: Click on the citation and log in to your profile search engine. Enter the author’s name in the search box and see the result.
- Scopus: Enter the author’s name in the search box of the homepage. Click on the author’s name and the citations. The required information and the h-index will be displayed in the upper right corner.
- ISI: Enter the author’s name in the ISI database, select the author’s name and click on the citation in the results section, then the h-index and all citations will be displayed.
