Indicators for journals evaluation

Selected indicators for scientific journals evaluation:

Essential indicators:

Impact Factor

“The annual JCR impact factor is a ratio between citations and recent citable items published. Thus, the impact factor of a journal is calculated by dividing the number of current year citations to the source items published in that journal during the previous two years” See: on Thomson Reuters website.

The Polish Ministry of Science and Higher Education scores

Hirsch index

The index h is defined as the number of papers with citation number >= h, as a useful index to characterize the scientific output of a researcher. An index to quantify an individual’s scientific research output.” It can be also used for journals’ evaluation. The h-index was developed by J.E. Hirsch and published in Proceedings of the National Academy of Sciences of the United States of America 102 (46): 16569-16572 November 15 2005.

Index Copernicus

This evaluation system includes selected journals from STM (Science, Technology, Medicine). It shows the rank of journals based on about 30 parameters in five categories:  scientific quality, editorial quality, international availability, market frequency, regularity and stability, technical quality. The IC Journal Master List – contains currently over 8,000 journals from all over the world, including 700 journals from Poland. The journals registered in this database underwent rigorous, multidimensional parameterization, proving high quality. The Ministry of Science and Higher Education acknowledged the IC Journal Master List by placing it on the list of scored databases. The journals indexed in IC JML get additional points during the Ministry’s evaluation process.

Additional indicators:


Source Normalized Impact per Paper - “SNIP measures a source’s contextual citation impact by weighting citations based on the total number of citations in a given  subject field. It helps you make a direct comparison of sources in different subject fields.”


SCImago Journal Rank- ”SJR is weighted by the prestige of the subject field, quality, and reputation of the journal – they all have a direct impact on the value of a citation.”

Sources of the indicators described above:

  • Journal Citation Reports - Online Access to JCR (since 1997) on Web of Science
    • Journal Citation Reports (JCR) Science Edition
    • Journal Citation Reports (JCR) Social Sciences Edition

    The current list of journals with the IFs is published mid-year of the following year.
    When looking for JCR database, choose "Additional Resources" after entering the platform ISI Web of Knowledge.

  • Master Journal List - Master Journal List is in Poland commonly called „lista filadelfijska”. The Master Journal List includes all journal titles covered in scientific products of Thomson Reuters, available on the ISI Web of Knowledge platform, among others in Web of Science (WoS) database. The Master Journal List is than broader than the list of journals available both in WoS and in JCR database.

    There is no information on Impact Factor values in the Master Journal List

  • List of the Ministry’s scored journals - The Ministry of Science and Higher Education publish a list of scored journals once a year. It consists of three parts:

    A – Journals with Impact Factor – IF, available in JCR database (20 to 50 points)
    B – Journals that do not have IF (0,25 to 10 poins)
    C – Journals available in European Reference Index for the Humanities (ERIH) database (12/16/20 points)

    Application form for a scientific journal -The application form for submitting the scientific journal for evaluation in accordance with the criteria and procedures published by the Ministry of Science and Higher Education. This application form is available through the Polish Scholarly Bibliography (Polska Bibliografia Naukowa, PBN), which is part of POL-on - System of Information on Higher Education.

  • INDEX COPERNICUS JOURNALS MASTER LIST (JML) - Current values of Index Copernicus (IC) factors for individual titles, estimated rates for the next year, journal’s publishing address, URL journal’s address, language of publication, availability in international databases). Data are available only for authorized users.
  • Scopus - It is an abstract and citation database where the number of citations, the value of h-index (Hirsch index) can be found (publications since 1996). It is also possible to compare scientific journals using the Journal Analyzer feature.
