How the unified institutional pathway works

Institutional research performance in the OpenAlex article/review index, linked to verified ResearchHub university identities. Not a measure of teaching or reputation. This version applies to newly created 2026.3 editions and fetches the complete institutional research window rather than relying on the locally admitted paper corpus. Existing published snapshots retain their recorded methodology and weights. The earlier 2026.2 pathway remains reproducible as a separate admitted-publication-corpus method.

One source-native OpenAlex work per verified institution, using direct paper affiliations; articles and reviews only; retracted works excluded. Full institutional counting; provider totals are never added together. Five complete UTC calendar years before the release start year. The evidence cutoff is captured after refresh; the window is frozen even if processing crosses New Year.

Quality uses only OpenAlex work-level normalized top-10% flags; raw citation counts from different providers are never combined or substituted. A Scopus API key does not imply SciVal access. All five metrics and fixed weights are required. Explicit quality, country and OA classifications must cover at least 90% of the window. Growth requires at least 20 articles/reviews in the first two years. Unknown evidence remains unavailable.

Each metric is converted to a within-snapshot percentile among the same fully eligible institutions. At least two comparable institutions are required. Overall points equal the sum of each pillar percentile × its fixed points / 100. Availability measures coverage; source and affiliation quality determine confidence separately.

International collaboration measures indexed works with at least two represented countries, among works with a known country. Open access and quality use explicit OpenAlex classifications. Every rate requires at least 90% known status. Other permitted providers enrich publication context and identity; their citation totals are never summed or substituted into the quality indicator.

Configured credentials do not guarantee evidence is available. A source contributes only through records actually collected and admitted. Growth reflects the indexed corpus and may be affected by changes in coverage; it is not an estimate of total institutional growth.
