Helpful information Citation Index

The citation index is an indicator of the “significance” of a scientist’s works, accepted in the scientific world, and is the number of references to a scientist’s publications in peer-reviewed scientific periodicals. The presence of scientists with a high index in scientific and educational organizations indicates the high efficiency and effectiveness of the organization as a whole. The Hirsch index is a scientometric indicator proposed in 2005 by the American physicist Jorge Hirsch from the University of San Diego, California as an alternative to the classic “citation index” – the total number of references to a scientist’s work. The criterion is based on taking into account the number of publications of the researcher and the number of citations of these publications. Those a scientist has an index h if h of his N articles are cited at least h times each. Impact factor (IF) is a formal numerical indicator of the importance of a scientific journal; it shows how many times, on average, each article published in a journal is cited within two subsequent years after publication. The impact factors of journals are fundamentally different for different disciplines. Russian Science Citation Index (RSCI) – The Russian Science Citation Index (RSCI) is a national information and analytical system that accumulates more than 2 million publications of Russian authors, as well as information on citing these publications from more than 2,000 Russian journals. It is intended not only for the operational provision of scientific research with relevant reference and bibliographic information, but is also a powerful tool for assessing the effectiveness and efficiency of research organizations, scientists, and the level of scientific journals. International citation system. The most authoritative of the existing international citation systems, whose indices are recognized all over the world, are: “Web of Science” and its competitor – the relatively young system “Scopus”. The journals included in these systems are officially recognized by the Higher Attestation Commission (HAC). The “Web of Science” system (formerly the Institute for Scientific Information, ISI) covers more than 9000 publications in English and partly in German (since 1980) and includes three bases – Science Citation Index Expanded (in natural sciences), Social Sciences Citation Index (social sciences), Arts and Humanities Citation Index (arts and humanities). The percentage ratio between the disciplines presented in the Web of Science resource is as follows: 25-27% – technical and applied sciences, 30% – social sciences, 43-45% – natural sciences (including 15-18% – science earth, biology and medicine). The Scopus system is the world’s largest unified multidisciplinary abstract database (since 1995), which is updated daily. Scopus is the largest scientific publication database without full texts. One of the main features is the citation information built into the search engine. Scopus covers over 15 thousand scientific journals from 4 thousand scientific publishing houses of the world, including about 200 Russian journals, 13 million patents of the USA, Europe and Japan, materials of scientific conferences. Scopus, unlike Web of Science, does not include publications in the humanities and arts, contains a small share of social science journals – no more than 17%, and in percentage terms reflects natural sciences and technology much more broadly – 83%.
