Scientometrics and management of scientific activities: once again about the global and Ukrainian

The main purpose of the paper is to perform a short review on the problem of implementation of scientometric indicators for research evaluation in the context of Ukraine. Peculiarities of usage of key scientometric terms in normative documents are examined. A number of case studies are given to illustrate the ambiguity of application of particular indicators in order to rate authors, research groups, institutions or scientific journals. The importance of balance between expert evaluation and quantitative analysis in the national system of research evaluation is highlighted, and the inadmissibility of any manipulations of scientometrical terms and notions is underscored.
