USE OF THE LINK RANKING METHOD TO EVALUATE SCIENTIFIC ACTIVITIES OF SCIENTIFIC SPACE SUBJECTS

A modification of the PageRank method based on link ranking is proposed to evaluate the research results of subjects of the scientific space, taking into account selfcitation. The method of reducing the influence of self-citation on the final evaluation of the results of research activity of subject...

The method of reducing the influence of self-citation on the final evaluation of the results of research activity of subjects of the scientific space is described. The evaluation of the results of research is calculated using the modified PR-q method, taking into account self-citation as a solution of a system of linear algebraic equations, matrix of which consists of coefficients determined by the number of citations of publications of one scientist in the publications of another scientist.
