The Hirsch Index is an international quality standard that determines the value of a scientist's scientific contribution. A high h-index indicates that scientific figures are regularly published and their work is actively cited, which indicates the high quality of their research. Today we will consider the advantages, disadvantages and method of calculating the h-index.
What is the Hirsch Index?
The Hirsch Index - an author-level scientometric indicator that measures the value and citability of scientific publications. H-index is a kind of generally accepted scientific statistics of the productivity of scientific activity of scientists. This metric takes into account not only the number of publications of a scientist, but also the number of citations of scientific papers.
The Hirsch index is primarily useful for comparing the influence and effectiveness of scientists' research activities within specific fields of knowledge.
The Hirsch index plays an important role in selection for academic positions and is taken into account when applying for research grants.
Calculation of H-index
Advantages of the Hirsch Index:
- With the help of this metric it is possible to get a comprehensive assessment of the scientist's activity. Not only the number of publications is taken into account, but also their quality (citation by other researchers).
- easy calculation: global databases - Scopus, Web of Science, Google Scholar - automatically calculate a scientist's h-index.
- coverage of all disciplines: the indicator is universal for all disciplines, so it is possible to compare the productivity of researchers from different fields of knowledge.
- objective assessment of scientific activity: compared to other indicators of influence, the h-index honestly assesses the effectiveness of a scientist's work. For example, getting a high citation by one article will not significantly affect the overall Hirsch Index score if the rest of the papers were not cited in the works of other scientists.
Disadvantages of the Hirsch Index:
- The indicator does not take into account the specificity of citation of articles in different fields of knowledge. As is known, scientific papers in the field of natural ortechnical sciences are cited much more often than publications in the humanities or social sciences
- Hirsch index, as a rule, is higher for researchers with more experience in the scientific field compared to young scientists. This indicator directly depends on the number of publications, while novice scientists tend to have fewer publications
- h-index may not reflect the actual scientific achievements of a scientist due to excessive self-citation or references by other researchers without objective grounds.
Despite some limitations, the Hirsch index most accurately reflects the productivity of a scientist's scientific activity compared to other metrics, as it takes into account not only the quantity but also the quality of scientific publications. The Hirsch Index is the primary metric that committee members look at when allocating academic positions at universities and research grants. If you need to increase your Hirsch Index in a short period of time, do not waste time, contact the experts of Scientific Publications. We cooperate with scientists all over the world and have thousands of successful cases. Leave your request if you need to increase Hirsch index in the international database Scopus or Web of Science and we will form a proposal specifically for you.
