Abstract: Bibliometric profiles of researchers are formed from scientific publications in various thematic fields. The most influential publications crate the thematic core of the researcher’s bibliometric profile. Apart from monitoring of the publication activity of a given researcher or computing his/her h-index, an important task of scientometrics has to involve a study of the thematic core of his/her publications. The article’s objective is to perform scientometric assessment of the thematic core of the researcher’s publications. This objective is achieved by modifying the methods for linguistic statistical analysis of the thematic concentration of words in the text and h-index, to substantiate determining the thematic core of publications. Data from the bibliometric database Google Scholar are used to form the researcher’s profile (the case of Ioan-Iovitz Popescu, a Romanian physicist-linguist). They use is explained by easy access to bibliometric profiles; by the possibility of including conference proceedings and non-English publications and making a retrospective analysis of the dynamics of references to publications and h-index.
The occurrence of publications in various research fields in the thematic core of the current bibliometric profile of the researcher is not an incidence, but a consequence of regular processes involved in the formation of thematic cores in individual thematic fields (disciplinary or interdisciplinary ones). Making a list of all the main thematic publications broadens the possibilities for sound assessment of the diversity of the creative activities of a researcher and his/her talents. It is shown that the thematic core of the researcher’s bibliometric profile represents all the thematic fields of his/her research. Use of the thematic core of publications as a methodical tool increases the capacities for bibliometric and scientometrtic analysis of the publication activity of a researcher. Results of the study demonstrate that compiling a list of publications making the thematic core of the researcher’s bibliographic profile can be more important in the research performance assessment, than computing his/her h-index.
