The h-index (or h-factor), created by physicist Jorge Hirsch in 2005, is an indicator of the impact of a researcher's publications. It takes into account the number of publications of a researcher and the number of their citations.
The h-index of an author is equal to the highest number h of his publications which received at least h citations each.
Example: an h-index of 6 means that 6 publications by the author have each been cited at least 6 times.
The h-index is calculated by ranking and numbering the author's publications from most cited (#1) to least cited. The h-index corresponds to the last number of the publication which verifies: number of citations ≥ publication number.
A researcher's h-index is increasingly requested in submission files for calls for projects or in the context of research evaluations.
The h-index can also be calculated for a research entity (institution, laboratory, etc.), or for a journal. The considered author is the name of the entity (laboratory, institution, etc.) or the title of the journal.
The h-index is like a score that shows how important a researcher's work is. It considers both the number of articles they have published and how often those articles have been cited by other researchers.
Here's how it works: If a researcher has an h-index of 10, it means they have published at least 10 articles, and each of those articles has been cited by other researchers at least 10 times.
So, the h-index tells us that the researcher's work is respected and has made an impact on other scholars.
This helps in comparing the influence of different researchers. A higher h-index generally indicates that a researcher's work has had more impact and recognition in the academic world. One more point being that the h-index can vary depending on the field of study, as some disciplines tend to have higher citation rates than others.
Hope that helps Anis Hamza , Best Regards
h- index can be better if
we have self cited h-index and other cited h-index
h- index dose not how much and an author contributed in an article it would be good if we have h-index that consider the order of authors
The h-index is counted for journals too. There are different metrics and rating in the academia
