Rightly associated with the analysis of scientific publications (scientometrics), bibliometrics is a set of quantitative (statistical and mathematical) methods used to analyze scientific writing. It is used to compare, rank and assess the impact of:

• the achievements of individual authors,
• of individual publications,
• journals,
• scientific institutions,
• also makes it possible to track the development of science nationally, as well as globally.

To determine scientific potential, bibliometric analysis relies on various factors of a numerical nature: scores (according to the guidelines of the Ministry of Science and Education) and indicators (such as the Hirsch index, Impact Factor, or number of citations), and specific tools (such as InCites, or SciVal) and databases (such as Web of Science, Scopus, or Google Scholar). Evaluation of scientific potential is not only a quantitative assessment, but also a qualitative one, so based on publication scores and citation analysis, bibliometric analysis sometimes requires additional calculations, the use of many different indicators together, taking into account domain specificity, or expert interpretation.
