DataCite 2026-07 Exact Affiliation Usage

This dataset contains exact, case-sensitive affiliation strings from both DataCite creators and contributors. Every placement contributes one occurrence count; repeated placements on a DOI are retained. DOI count is distinct per exact affiliation.

Contents

  • Distinct DataCite DOIs, including DOI records without affiliations: 132,801,254
  • Valid DOI source records (DOI stream rows): 132,801,303
  • Valid affiliation occurrences: 334,593,737
  • Exact affiliation rows: 1,681,662
  • Distinct DOI-affiliation pairs: 112,023,092
  • Split: train
  • Train schema v3: exact affiliation totals plus explicit valid and invalid ROR attribution support. ror_ids contains canonical ROR IDs with occurrence and distinct-DOI support; most_common_ror_ids_* retain all lexical tie winners.
  • Sidecars: artifacts/doi-affiliation-attributions-.parquet records each exact DOI-affiliation-status attribution group, and artifacts/doi-prefix-population-.parquet records DOI-prefix source populations.

Normalized affiliations

The normalized split uses comet-datacite-ascii-v1: Unicode text is transliterated to ASCII, lowercased, stripped of punctuation while preserving internal whitespace, and trimmed. Empty results are excluded. Its columns are normalized_affiliation (string), total_occurrence_count (uint64), raw_affiliation_count (uint64), and doi_count (uint64), plus explicit ROR coverage and deterministic ROR support lists. DOI counts are calculated from the DOI-affiliation attribution sidecar after normalization, so one DOI shared by multiple exact variants is counted once for the normalized key. Compact per-prefix attribution rows are published under artifacts/normalized-prefix-attribution-*.parquet.
