In today's scientific environment, there are a significant number of scientometrics indicators that characterise the activity of scientists, institutions, organisations, etc. One of the main indicators of a scientist's activity is the Hirsch index. For young researchers, increasing this indicator is one of the key requirements for obtaining grants or funding for their projects. Today, we will look at the basic definitions of this metric and how it is calculated.
What is the Hirsch index?
The Hirsch index was proposed in 2005 by physicist Jorge Eduardo Hirsch from the University of California, San Diego. He developed this indicator as a convenient way to assess the scientific productivity and influence of researchers. The higher the index, the more significant the scientific work is considered to be for the academic community.
This indicator is actively used by universities, scientific foundations and various organisations to analyse the performance of scientists. National and international rankings take the Hirsch index into account when compiling lists of leading scientists, scientific institutions and higher education establishments.
How is the Hirsch index calculated?
The method for calculating this indicator is quite simple: the h-index is equal to the number h if a researcher has h publications, each of which has been cited at least h times. For example, a Hirsch index of 10 means that the author has 10 scientific articles, each of which has been cited at least 10 times.
To determine the Hirsch index, the following condition must be applied: h-index = the largest integer h for which at least h publications have at least h citations each. To better understand the calculation principle, let's look at a few examples.
The h-index is calculated by ranking the author's scientific publications by the number of citations, from the most cited to the least cited. After that, it is determined from which article the above condition for calculating the Hirsch index ceases to be met: the largest number h for which the author has h articles, each of which has at least h citations.
As can be seen, in both examples of index calculation, starting with articles 5 and 6, the previously described mandatory condition for calculating the index is not met. In the first example, article 5 has only 4 citations, and in the second example, article 6 has only 2 citations. Consequently, other publications with fewer than 4 citations in the first case and 5 in the second case do not affect the increase in this indicator and are not taken into account.
What does the Hirsch index affect?
Recognition in the scientific community
A high h-index automatically increases interest in publications and ensures that the author is included in the circle of leading scientists. The Hirsch index reflects the authority of the researcher and their work, showing that they are actively cited and have an impact in the scientific community.
It is an indicator of research quality, confirming that the results have not only been published but have also become useful to other scientists. Universities and scientific institutions often use this indicator as a criterion for evaluating a scientist's productivity.
Financial support
The higher the index, the higher the chances of receiving grants and scholarships necessary for the implementation of large-scale scientific projects. Grantors usually focus on researchers whose work has a proven impact and is widely used in scientific discourse.
A high h-index can be a compelling argument in applications for international support programmes, as it reflects stable and influential scientific activity.
Career opportunities
The Hirsch index is mainly used as one of the criteria for selecting scientists for editorial boards, appointing reviewers, or obtaining prestigious positions. For universities and research centres, this indicator is proof of high qualifications and recognition of a scientist in the global scientific community.
Publication prospects
The higher the h-index, the more opportunities it opens up for publication in authoritative scientific journals and conducting large-scale research.
The editorial boards of well-known publications often pay attention to the citation rate of authors, which increases the likelihood of an article being accepted for review and subsequently published.
In addition, a high Hirsch index promotes international cooperation, as colleagues from other countries are more willing to collaborate with researchers whose work has a significant impact on science.
The Hirsch index is one of the key indicators for assessing a scientist's productivity. It combines a quantitative characteristic of publication activity with a qualitative assessment of the impact of research through citations. A high h-index strengthens a researcher's scientific authority and opens up opportunities for grants, scholarships, etc. The index also increases the likelihood of collaboration with leading scientists around the world.
