About the ORBIT Ranking
ORBIT—Objective Ranking through Bias-reduced Integrated Tiers—combines evidence from multiple expert-based journal ranking systems to produce a consensus score, letter grade, and uncertainty measure. The current version expands this evidence base by integrating KI.
Scopus’s All Science Journal Classification (ASJC) is used to identify each journal’s subject areas and determine which ranking systems are relevant to its field. A journal must have evidence from at least two eligible ranking systems before receiving an ORBIT score and grade. Business-oriented rankings are used only when the journal’s ASJC classification makes them relevant.
After the score-based grade is assigned, inclusion on an Elite List raises the grade by one level, while inclusion on the Warning List lowers it by one level. Adjustments are capped at A+ and floored at D. If a journal appears on both lists, no adjustment is applied.
The uncertainty score measures disagreement among the eligible ranking systems. It is calculated from the weighted cross-system variation and min–max normalized to a 0–1 scale. It is descriptive and does not change the journal’s grade.

Ranking systems used to calculate ORBIT scores
The systems used for an individual journal depend on its Scopus ASJC classification and available coverage.
Grade-adjustment lists
- Elite: ARWU, FT50, Nature Index and UTD24
- Warning: CAS Early Warning Journal List
These lists adjust the score-based grade by one level; they are not treated as additional scoring systems and do not satisfy the two-system coverage requirement.
Classification and metadata
ORBIT uses Scopus data for journal metadata and the All Science Journal Classification (ASJC), which guides field classification and the selection of relevant ranking systems. Scopus supplies publisher information and open-access status, and ASJC classifications guide the selection of field-relevant ranking systems.
Conference Ranking
ORBIT provides a structured and reliability-aware ranking of academic conferences by integrating evidence from three expert-driven systems: CORE, JUFO, and the Norwegian Register. Each system's discrete tiers are first mapped to a common 0-100 scale using percentile-based midpoints, after which an ORBIT score is computed as a reliability-weighted average over the systems available for a given conference, requiring at least two systems.
Final letter grades (D through A+) are assigned using fixed score thresholds, with journal Elite and Warning lists now applied as one-step grade adjustments instead of fixed final labels. Alongside the grade, ORBIT reports an uncertainty measure that reflects cross-system agreement: uncertainty is lower when systems concur and place a venue near the top tiers, and higher when signals diverge or coverage is sparse.
Source Rankings
ORBIT only includes conferences which are ranked by at least two of our used rankings/lists. We currently use the following expert-based rankings/lists:
Publisher Ranking
ORBIT provides a conservative, transparent ranking of academic publishers based on the overlap of two independent expert systems: JUFO and the Norwegian Register. While percentile-based 0-100 scores are computed for reporting, the final letter grade is determined only by the pair of JUFO level and Norwegian level, using a fixed rubric that is fully auditable.
The top grade A+ is assigned only when JUFO = 3 and Norwegian = 2, making grade inflation unlikely and keeping top tiers intentionally selective. Grades are issued only when both systems are present; missing values are treated as lack of evidence rather than low quality. A companion reliability indicator is reported as the cross-system disagreement, where larger disagreement implies lower confidence in the assigned grade.
