Selecting a journal for publication in Scopus is an important step that requires careful analysis and consideration of the publication's scientometric indicators. What metrics should be paid attention to when selecting a scientific journal for publication - we will analyze in this article.
Main citation metrics of Scopus journals
Qualitative and quantitative characteristics that are used to assess the impact of scientific journals included in Scopus:
-
CiteScore (Citation Index)
CiteScore is one of the main scientific metrics of Scopus, showing the average number of citations per article published in an academic journal. Publications with a high CiteScore have a greater impact in their subject area.
This metric is designed to present a clear and simple indicator of a journal's influence and quality in academia.
How is the CiteScore of a journal calculated?
The CiteScore calculation for the current year is based on the number of citations received by the journal in the last 4 years (including the year of calculation) divided by the number of articles published in the journal in those four years. The formula for calculating the CiteScore for 2023 is:
Example of the CiteScore indicator of a journal in Scopus:
-
SJR (SCImago Journal Rank)
SJR is a metric used to assess the scientific impact of journals. It takes into account not only the number of citations, but also the authority of the publications referring to this journal. This indicator was developed by SCImago Lab and is based on data from the Scopus platform.
The SJR ranking of journals is updated annually on the online platform Ssimago Journal & Country Rank and on the Scopus website.
Unlike simple citation counting, SJR takes into account the "weight" of citations. This means that a citation from a more prestigious journal has more weight than one from a less reputable journal. Thus, SJR takes into account the quality, not only the number of citations.
High SJR values indicate a journal's great influence and authority in its field.
How is a journal's SJR calculated?
The formula for calculatingSJR for 2023:
The indicator displays the average number of weighted citations received by articles in a particular year published in the journal over the previous three years - weighted citations received in year N by articles published in the journal over a three-year period.
-
SNIP (Source Normalized Impact per Paper)
SNIP is a metric that is used to assess the impact of academic articles taking into account the citation context in different academic fields. SNIP measures the actual number of citations received relative to the expected number of citations for the subject area of an academic publication. It is a useful indicator for understanding the relative influence of a journal in a particular field of study. The indicator was introduced by Elsevier.
SNIP takes into account that different subject areas have different citation rates. For example, some fields, such as medicine or physics, may have higher citation rates than the humanities. SNIP adjusts for this difference so that journals from different fields can be compared more objectively.
Formula for calculating SNIP:
The SNIP formula takes into account the total citations of a journal and the number of articles in the journal, adjusted for citation patterns in a given scientific field:
SNIP is used to assess the impact of scientific journals based on their field and citation context. It is a useful indicator for journal selection, especially if your research is in a field where citation norms differ significantly from other disciplines.
-
Quartile
All journals included in Scopus are divided into four main categories - quartiles - based on their impact and citation rates.
A quartile is a ranking of scientific journals based on their citation rates. Journals are divided into four groups or quartiles (Q1, Q2, Q3, Q4) based on their position in the rankings according to key metrics such as SJR (SCImago Journal Rank) or CiteScore.
Journals from the first quartile (Q1) are considered the most prestigious.
Why is it important to consider citation metrics when selecting a journal for publication?
The main indicators of journal influence - CiteScore, SJR, SNIP, Quartile - are an important criterion when selecting a journal for publication for the following reasons:
- journal reputation assessment: publications with high scientometric indicators are considered more prestigious for publication, while placing an article in journals with low rankings can negatively affect a scientist's credibility
- Readership reach: publishing in journals with high CiteScore, SJR, SNIP, and Quartile metrics allows you to reach a broad scientific audience. It increases the likelihood that your work will be noticed and cited by other researchers
- Impact on academic career: Publications in highly citedand prestigious journals, especially those in the first or second quartile (Q1, Q2), can have a significant impact on a researcher's academic career. Such publications can be crucial when applying for grants, academic honors, or conference invitations.
