Scientometric indicators

Scientometric indicators – indexes of the publication activity of authors or organizations, the significance of publications depending on the scientific weight of the journal, etc. They are used to assess the state and prospects of research activities of authors and organizations, compare them and rank them in various ratings.

Today, there are a large number of international citation systems (bibliographic databases): Web of Science, Scopus, Astrophysics, PubMed, Mathematics, Chemical Abstracts, Springer, etc. The most authoritative of the existing international citation systems, whose indexes are recognized worldwide, are: Web of Science and the Scopus system. Journals included in these systems are officially recognized by the KKSON of the Ministry of education and science of the Republic of Kazakhstan.

Web of Science is an information and analytical platform with information about leading international publications. Its history begins with the Science Citation Index, which has been published by the Institute of Scientific Information (ISI) since 1964 under the leadership of the founder of scientometry, Eugene Garfield.

In 2017, the independent company Clarivate Analytics continued the ISI tradition and developed tools for the full cycle of scientific and technical information. Web of Science remains one of the main information platforms of Clarivate Analytics and continues to develop.

Citation indexes ar.

The calculation of citation indicators in each specific resource is based on the information (sources) contained in this particular resource, so the citation indicators of the same author in different resources may differ.

What is the impact factor?
There
are two standard ways to assess the level of scientists. The first is the citation index, and the second is the impact factor.

The impact factor was proposed in the 1960s by Eugene Garfield, a structural linguist and founder of the Institute of Scientific Information (ISI) in Pennsylvania (USA). This is a relative indicator of citation of articles in the journal.

The impact factor is calculated as follows: the number of citations in the reporting year of articles published in the journal for the previous two years is divided by the total number of these articles. The fewer issues a publication has, the greater the contribution of each individual citation.

The impact factor is an important characteristic of scientific journals. It is calculated each year By the Institute for scientific information (ISI). The impact factor of a journal is the ratio of the number of references for a certain period (usually 3 years) to articles in this journal to the number of articles published in it.

The impact factor reflects the quality of papers published in journals through the evaluation of productivity and citation, i.e., the scientific popularity of the journal.
