It is very important to know What is an H-index? Just as research papers and journals are graded and validated based on specific indicators, researchers are no exception. To determine the scientific nature of a researcher’s research papers, and H-index is considered for him.

What is an H-index and how is it evaluated?

The H or H-Index is a numerical scale that shows how effective a researcher has been. The index was invented in 2005 by a physicist named George Hirsch at the University of California. The purpose of inventing this numerical scale was to determine how successful each researcher was in their scientific field.

At that time, this assessment was done through the number of citations to a person’s article. If you wanted to know how influential a researcher was, all you had to do was calculate how many times others had referred to his article. It was very simple, but researchers soon found fault with this type of assessment.

In this type of evaluation, if a researcher had published only one scientific article that has been referred to a lot, he would have been called a successful researcher. In such a situation, other researchers who have published more than one article did not seem to play an effective role.

To correct this problem, Hirsch proposed another method, known as the H-index (H is derived from the name Hirsch). Hirsch describes this index as follows:

“A researcher has an H index when H has at least one H reference from his or her NP research papers, and other NP-H research papers have not referenced more than H each.”

We will explain this to you in simpler language.

The H index of each researcher is based on the number of his or her research papers(H), each of which is referred to at least H times. For example, if the H index of a researcher is 28, that is, it has 28 scientific articles, each of which has been referenced at least 28 times in other articles. This means that a researcher’s credibility is determined by the number of high-level articles he or she publishes, not just one or two articles that score well.

Therefore, if a researcher wants to increase his H index, he should encourage others to read his articles and refer to them in his scientific research papers. In this case, focusing on just one or two well-crafted articles is not a privilege for a researcher.

What effect does the H-Index have?

While the H index may seem to be used solely to score points for researchers in various fields, it is more efficient. First, researchers themselves can measure their own and others’ activities based on this score. Especially for jobs in the scientific field, the H index is very effective.

It also helps people who don’t know or specialize in a particular field to be able to more easily assess a researcher’s credibility. For example, in a job interview for specific research or scientific job where the interviewer does not have very specific information about the academic background of the interviewee, given his or her H score, he or she can better decide how effective and efficient that person can be.

What is the problem with the H index?

Although the H index has been very effective and has many benefits, it still has its drawbacks. One of these is when we compare the H score in different fields. In some fields (such as economics), the H-index of researchers usually has a higher score than some other fields (literature review). Therefore, it may be misunderstood that two people with the same amount of knowledge do not have the same amount of influence in their field of expertise.

Also, the H score can be manipulated, for example, one of the problems is that people can ask their friends and acquaintances to constantly refer to their research papers in their articles to increase the number of citations to their research papers. But this does not necessarily mean that his articles have a high scientific burden.

H index in scientific websites

You can find the author’s H-Index on Internet sites such as Scopus or Google Scholar.

H index at Scopus database

In the Scopus database, just enter the Author Search page and enter the desired name. After you find the author you want in the list, click on his name, and enter his profile page. On this page on the right you can see the h-index of the person and the number of research papers he has placed on the site and the number of citations to the person’s article. At the bottom of the page in the Documents section, you can also see the articles he has published and the number of citations to each article.

H index in Google Scholar database

In Google Scholar, you can get a researcher’s h-index score in three ways. First, if you know the researcher’s name, you can enter it in the Advanced Setting section to find him and see his profile. Or search for his name in this field in the search field. Author: author-name

If you don’t know the researcher’s name and just want to know what the author of the article you want to cite is, just click on the author’s name to open his profile page after searching for the topic you want and selecting the article. On the right side of an author’s profile page on Google Scholar, you can see the number of citations to the author’s research papers, the number of research papers, and his or her h points, and on the left, you can find the number of articles he or she has published. An author’s articles are shown in the most referenced order, which can help you choose an article that is more scientifically relevant.

H-index in ISI database

The ISI site should have access to this section so that you can search for the author’s name and find his H-index.

Calculate the h-index manually

To get the H number manually, after you’ve searched for the author’s name and seen the results in different years, sort his research papers by descent and compare the number of articles with the number of citations to the extent that The citation is equal to or greater than the number of the article. The number of that article represents the author’s H index. For example, if the author has published ten articles, 6 of which have been cited at least 6 times, the H index of that author is 6.

A researcher’s H index can help you choose better and more useful research papers. The higher a writer’s H score, the more likely he or she is to be better known and his or her academic papers to be more credible, so using his or her scientific theories in your dissertation or dissertation can add credibility to your research work.

About KSRA

The Kavian Scientific Research Association (KSRA) is a non-profit research organization to provide research / educational services in December 2013. The members of the community had formed a virtual group on the Viber social network. The core of the Kavian Scientific Association was formed with these members as founders. These individuals, led by Professor Siavash Kaviani, decided to launch a scientific / research association with an emphasis on education.

KSRA research association, as a non-profit research firm, is committed to providing research services in the field of knowledge. The main beneficiaries of this association are public or private knowledge-based companies, students, researchers, researchers, professors, universities, and industrial and semi-industrial centers around the world.

Our main services Based on Education for all spectrums people in the world. We want to make an integration between researches and educations. We believe education is the main right of Human beings. So our services should be concentrated on inclusive education.

The KSRA team partners with local under-served communities around the world to improve the access to and quality of knowledge based on education, amplify and augment learning programs where they exist, and create new opportunities for e-learning where traditional education systems are lacking or non-existent.
