Scientometrics – a section of the science which studies the evolution of science through numerous scientific information measurement such as the number of scientific papers published in this period, citation and so on.

The main task of the Scientometrics is to study the activity of Publications and citation authors of scientific papers.

The effectiveness of scientific activity can be evaluated using both qualitative and quantitative indicators. The basis of qualitative assessments are expert. The subjectivity of such assessments reduces the reliability of the results obtained.

Quantitative estimates are based on published data and patent information, number of publications, analysis of frequency of citation (citation index), Hirsch index, the impact factor of scientific journal in which the work is published, the number of received national and international grants, scholarships, national and foreign awards participation in international scientific collaboration, part of the editorial boards of scientific journals.

The most authoritative and complete international database is designed to study the activity of research (scientists, organizations) bibliometric indicators:
Web of Science (WoS) Philadelphia Institute for Scientific Information Thomson Reuters Corporation Publishing Corporation Scopus Elsevier.
Their data are captured in various international and national rating systems.

Thomson Reuter’s Web of Science Corporation– the world’s most authoritative analytical and Quotation database of journal articles that unites three bases: Science / Social, Sciences / Arts & Humanities, Citation Index. (Access to them is limited only by subscription). These resources do not contain the full text of articles; however, they include a link to the full text in the original sources and lists of citations found in every publication that allows you to quickly get the most complete bibliography on the subject (depth archive – 20 years).

The database Scopus in many countries is one of the main sources of data for scientometric evaluation studies on the national or corporate level. It is a commercial database (DB) and its full version is only available on a subscription basis via the web interface.

Citation index – accepted in the scientific world measure of the significance of scientific work of a scientist or scientific community. The value citation index is determined by the number of references to the publication or author’s name elsewhere. However, to accurately determine the significance of scientific works is important not only the number of links to them, but also the quality of those links.

Currently citation index is recognized as one of the most effective indicators of the global scientific information.

H-index or Hirsha index – a scientometric indicator, which is a quantitative characteristic performance of the group of scientists, university or country as a whole, based on consideration of the number of publications and number of citations of these publications.

Impact factor-a numerical measure of the importance of a scientific journal. Calculated annually by the Institute of Scientific Information, which in 1992 was acquired by Thomson and published in the «Journal Citation Report».

According to the impact, factor journals estimate the level of quality of articles published there, give financial support to researchers. Impact factor though is great, but ambiguously estimated impact on the assessment of research results.

Russian scientific citation index (RSCI)

Russian scientific citation index (RSCI) – an international bibliographic database of scientific publications of scientists.

Russian scientific citation index (RSCI) – a mechanism to evaluate the level of scientific publication based on formal and objective criteria. The main criterion is thus relative citation index of articles published in this magazine, that is, its impact factor.

The main problem being solved by RSCI  project, can be briefly summarized as follows:
– The creation of multi-search engine with the publications of Russian scientists and scholars from any country, including the first stage of the project articles from scientific journals (journals amount presented in the project is at least 1,000 names);
– Development of mechanisms and tools for statistical analysis of domestic science;
– The creation and formation of the Single Registry of publications of Russian scientists, an authoritative database that represents the most complete and accurate information about Publication flow of Russian scientists, regardless of source, time, place and type of publication;
– An effective system of navigation in an array of scientific information and access to Russian users full-text publications through the mechanisms of the system of unified access.

Index Copernicus

Index Copernicus (IC) (Poland) – international scientometric database (Index Copernicus Journals Master List). This website includes indexing, ranking and abstracting journals, and is a platform for scientific collaboration and joint research projects. The database has several tools to evaluate performance, to monitor the impact of scientific papers and publications of individual scientists or scientific institutions. In addition to assessing, the performance of Index Copernicus also offers traditional abstracting and indexing publications.

Its scientometric indicators can also track the resource as Google Scholar.

Google Scholar (Google Scholar) – is freely available search engine that provides full text search of scientific publications of all sizes and disciplines.

Using a single inquiry form, you can search for different disciplines and different sources.

However, be aware that scientometric indicators on all these resources will be different. In RSCI, there are mainly magazines of former Soviet Union; Google Scholar publication indexes are around the world.

Note that Hirsch index in Scopus is the most prestigious and the only indicator that is important for the global scientific community.
