Journal Impact Factor (Clarivate Analytics)

The annual Journal Citation Report 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 by the source items published in that journal during the previous two years.

The 5-year impact factor is calculated by applying the counted articles to the previous five years.

SCOPUS CiteScore

Calculating the CiteScore is based on the number of citations to documents (articles, reviews, conference papers, book chapters, and data papers) by a journal over four years, divided by the number of the same document types indexed in Scopus and published in those same four years.

SNIP (CWTS)

The Source Normalized Impact per Paper (SNIP) measures contextual citation impact by weighting citations based on the total number of citations in a subject field. The impact of a single citation is given higher value in subject areas where citations are less likely, and vice versa.

  • Measures contextual citation impact by "normalizing" citation values;
  • Takes a research field's citation frequency into account;
  • Considers immediacy – how quickly a paper is likely to have an impact in a given field;
  • Accounts for how well the field is covered by the underlying database;
  • Calculates without use of a journal's subject classification to avoid delimitation;
  • Counters any potential for editorial manipulation.

IPP (CWTS)

The impact per publication, calculated as the number of citations given in the present year to publications in the past three years divided by the total number of publications in the past three years.

SJR (Scimago Journal Rank)

The SCImago Journal Rank (SJR) is a prestige metric based on the idea that "all citations are not created equal". With SJR, the subject field, quality and reputation of the journal have a direct effect on the value of a citation.

  • Is weighted by the prestige of the journal, thereby "leveling the playing field" among journals;
  • Eliminates manipulation: raise the SJR ranking by being published in more reputable journals;
  • "Shares" a journal's prestige equally over the total number of citations in that journal;
  • Normalizes for differences in citation behavior between subject fields.

Scimago H Index

The h index expresses the journal's number of articles (h) that have received at least h citations. It quantifies both journal scientific productivity and scientific impact and it is also applicable to scientists, countries, etc. The value displayed comes from SCImago.

Source: Scimago Lab

Google Scholar metrics

The h-index of a publication is the largest number h such that at least h articles in that publication were cited at least h times each. For example, a publication with five articles cited by, respectively, 17, 9, 6, 3, and 2, has the h-index of 3.

The h5-index of a publication is, respectively, the h-index, of only those of its articles that were published in the last five complete calendar years.
