12 Scientifc Journal of Astana IT University ISSN: 2707-904X USE OF THE LINK RANKING METHOD TO EVALUATE SCIENTIFIC ACTIVITIES OF SCIENTIFIC SPACE SUBJECTS Abstract: A modifcation of the PageRank method based on link ranking is proposed to evaluate the research results of subjects of the scientifc space, taking into account self- citation. The method of reducing the infuence of self-citation on the fnal evaluation of the results of research activity of subjects of the scientifc space is described. The evaluation of the results of research is calculated using the modifed PR-q method, taking into account self-citation as a solution of a system of linear algebraic equations, matrix of which consists of coeffcients determined by the number of citations of publications of one scientist in the publications of another scientist. The described method can be used for the task of evaluating the activity of the components of the scientifc space: scientists, higher education institutions and their structural units. For the task of evaluating the research activity of subjects of the scientifc space, a method based on link ranking (PageRank method for web pages) and taking into account the self- citation of scientists is proposed. The latter allows for an adequate assessment, taking into account the abuses associated with the authors’ excessive self-citation. The essence of the constructed method lies in the construction of a system of linear algebraic equations, whose coeffcients of the matrix refect the citations of some scientists by others in the citation network of scientifc publications. The value of the coeffcients of the matrix of such a system of linear algebraic equations is subject to certain restrictions, which allow to reduce the infuence of the factor of excessive self-citation of the author on his overall assessment of research activity. The described method can be used to calculate the complex evaluation of the components of the scientifc space: the scientist, the institution of higher education and its separate A.
