“Cites per paper” is a two-year cited-by rate computed from OpenAlex. It is not a Clarivate Journal Impact Factor — we neither compute nor license that metric (how the two differ). Citation rates differ enormously between fields, so compare within a discipline. What the other figures mean: journal quartile, SJR, h-index and article processing charge.

The quartile is the one Scimago prints for each category. Rank is the journal's position by SJR among the journals Scimago lists in that category (#1 is the highest); “—” means we hold no rank consistent with that quartile. The document count is what Scopus indexed that year, which can be lower than a journal's full output. Source: SCImago Journal Rank 2025 edition, from Scopus data (scimagojr.com, CC BY-NC).
International Journal of Uncertainty Fuzziness and Knowledge-Based Systems is Q3 in all 6 of its Scimago subject categories (2025 edition; best category Theoretical Computer Science: Q3, #96 of 128), with SJR 0.312 (Scimago) and an h-index of 72 (OpenAlex). Listed in Scopus, Web of Science.

Frequently asked
Is International Journal of Uncertainty Fuzziness and Knowledge-Based Systems a predatory journal?
Our screening does not flag International Journal of Uncertainty Fuzziness and Knowledge-Based Systems. That is not a guarantee of quality — it means the venue is not on Beall's archive (frozen since 2017) and does not match our name-pattern heuristic. It is listed in Scopus, Web of Science, which is a positive signal.
Is International Journal of Uncertainty Fuzziness and Knowledge-Based Systems indexed in Scopus or Web of Science?
Per our venue index, International Journal of Uncertainty Fuzziness and Knowledge-Based Systems appears in: Scopus, Web of Science. Index membership changes over time — confirm on the index's own site before relying on it.
What is the impact factor of International Journal of Uncertainty Fuzziness and Knowledge-Based Systems?
Papers in International Journal of Uncertainty Fuzziness and Knowledge-Based Systems are cited about 1.1 times each within two years of publication, and Scimago places it in Q3, with an h-index of 72. Those are the open equivalents: the Clarivate Journal Impact Factor is a proprietary metric we neither compute nor license, so we show the two-year citation rate and Scimago quartile instead — they answer the same question of how heavily the journal is cited. A citation rate is a property of a field as much as of a journal.
What Scimago quartile is International Journal of Uncertainty Fuzziness and Knowledge-Based Systems (Q1, Q2, Q3, or Q4)?
In the Scimago Journal Rank 2025 edition, International Journal of Uncertainty Fuzziness and Knowledge-Based Systems is Q3 in all 6 of its subject categories. By category: Theoretical Computer Science: Q3, #96 of 128; Control and Systems Engineering: Q3, #195 of 315; Information Systems: Q3, #257 of 434; Software: Q3, #257 of 392; Artificial Intelligence: Q3, #269 of 434; Applied Mathematics: Q3, #423 of 658. Quartiles split the journals in a subject category into four equal groups by SJR, so Q1 is the most-cited quarter and Q4 the least; International Journal of Uncertainty Fuzziness and Knowledge-Based Systems is cited about 1.1 times per paper over two years, with an h-index of 72.
What is the Web of Science (JCR) quartile of International Journal of Uncertainty Fuzziness and Knowledge-Based Systems?
The Web of Science quartile comes from Clarivate's Journal Citation Reports (JCR), a proprietary product we neither license nor compute — so we cannot state a JCR quartile for International Journal of Uncertainty Fuzziness and Knowledge-Based Systems. The open equivalent is its Scimago quartile, Q3, derived from Scopus citation data. Because JCR ranks against Web of Science and Scimago against Scopus, the two can differ, so check Clarivate's site directly if you need the JCR quartile specifically.
Is International Journal of Uncertainty Fuzziness and Knowledge-Based Systems open access?
Our index records its access status as "subscription". Where this is derived from publisher-level signals rather than works-level data it is a heuristic, so confirm on the journal's own site — particularly if an article processing charge matters to you.
