Citations count every citation the journal's papers received in these years, including citations to older papers. Two-year mean citedness is OpenAlex's measure of how often recent papers are cited; it is similar in idea to, but not the same as, an impact factor.

Transparent methodology

How the ITS Journal Score works

One formula applies to every ranked journal, using open data from OpenAlex: 45% citation impact, 35% h-index and 20% size (papers published 2021–2025). Citation impact is the smaller of the journal's two-year mean citedness and its five-year citations per paper, so a journal whose output collapsed cannot jump to the top on old citations. Each part is half a percentile and half a log-scaled value, so the very top is still separated. Growth and open-access share are shown separately and are not part of the score.

A journal is ranked only if it published at least 50 papers in 2021–2025 and was active in at least five of the last six years. Field rankings compare a journal only with journals in the same field; the field is the OpenAlex field with most of the journal's recent papers, or "Multidisciplinary" when no field has 30% of them.

What this is not: the ITS Journal Score is not a Journal Impact Factor, CiteScore or SJR, and this site does not say whether a journal is indexed in Scopus, Web of Science or PubMed. Always confirm aims and scope, indexing, peer review and fees on the journal's own website before you submit.
