Awareness indicator

This section presents a set of reputation indicators associated with scientific publications, providing researchers and academic institutions with essential tools to assess the impact and recognition of their work. Among these indicators, the Impact Factor (IF), the Scimago Journal Rank (SJR), the Eigenfactor, the Source Normalized Impact per Paper (SNIP), the Article Influence, the h-factor, and the g-factor occupy a central place. Each of these indicators is carefully defined, and details are provided regarding the publication and/or citation periods considered, the data source, the scope of study, and the online access modalities. These indicators play a crucial role in assessing the quality, influence, and reputation of scientific journals, individual researchers, and institutions, thus contributing to the advancement of academic research.

Impact Factor (IF):

    • Definition: Impact factor is an indicator that measures how often articles published in a journal have been cited in other publications over a given period.
    • Publication period: Usually, the FI is calculated over a two-year period, for example, from 2020 to 2021 for a journal published in 2020.
    • Source: It is usually calculated and published by Clarivate Analytics in the Journal Citation Reports (JCR).
    • Scope: It is based on citations of the journal’s articles within the Web of Science database.
    • Online access: The JCR is often accessible through university libraries or by subscription.

Scimago Journal Rank (SJR):

  • Definition: The SJR is an indicator that assesses the relative importance of scientific journals based on the number of citations received and the quality of the sources of these citations.
  • Publication period: It is generally based on a three-year period.
  • Source: The SJR is calculated and published by Scimago Lab from the Scopus database.
  • Scope: It covers a wide range of scientific fields.
  • Online access: The SJR is available online for free on the Scimago Lab website.

Eigenfactor:

        • Definition: The Eigenfactor measures the overall influence of a scientific journal based on the number of citations received and the quality of the journals that cite this journal.
        • Publication period: It is based on a five-year period.
        • Source: The Eigenfactor is calculated by the University of Washington from the Web of Science database.
        • Scope: It takes into account a wide range of academic journals.
        • Online access: Eigenfactor data is accessible online free of charge.

Source Normalized Impact per Paper (SNIP):

    • Definition: The SNIP assesses the impact of a journal based on the number of citations compared to the expected citation in its field.
    • Publication period: It is generally based on a three-year period.
    • Source: SNIP is calculated by Leiden University from the Scopus database.
    • Scope: It covers a wide range of academic fields.
    • Online access: SNIP data is available online.

Article Influence:

    • Definition: Article Influence measures the influence of a journal based on the number of citations received per article published in that journal.
    • Publication period: It is based on a five-year period.
    • Source: Article Influence is calculated by Eigenfactor.org from the Web of Science database.
    • Scope: It covers a wide range of academic journals.
    • Online Access: Article Influence data is available online.

h-factor (h-index):

    • Definition: The h factor measures a researcher’s productivity and impact based on the number of articles (h) that have received at least h citations.
    • Citation period: It is not based on a specific period of publication.
    • Source: It is usually calculated from citation databases like Google Scholar.
    • Scope: It applies to individual researchers rather than journals.

g-factor (g-index):

    • Definition: The g-factor is an extension of the h-factor that takes into account the total number of citations received by the articles included in the h-factor.
    • Citation period: It is not based on a specific period of publication.
    • Source: It is usually calculated from citation databases like Google Scholar.
    • Scope: It applies to individual researchers rather than journals.

These reputation indicators are used to assess the influence and recognition of scientific journals, individual researchers, and academic institutions. They are widely used in the research field to help assess the quality and impact of academic output.
