There has been completed an evaluation of the share of internationalized publications written by Russian scientists in 2014. It was demonstrated that no more than 8–10% of scientific publications written by Russian scientists, indexed in the National index of scientific citation, were reflected in international bibliometric data bases Web of Science and Scopus and only half of those were cited in the first three years after publication. The share of domestic publications, accessible to international scientific community is estimated in 5%.Based on the presented data, it was assumed that self-isolation of Russian science is progressing. It is was noted, that in circumstances when 95% of publications by Russian scientists remain inaccessible to an international scientific community and when there is no feedback received in the form of citations of presented outcomes, evaluating correspondence of the latter to international standards of research is significantly difficult. In order to identify the scientific capacity of Russian scientists, and to see how it is matching international frontlines of research, it is suggested to use methods of linguistic and semantic analysis on the basis of Exactus Expert system.
