Normalized affiliation overlap

This CC0 dataset partitions normalized affiliation strings by exact equality after the shared normalization contract.

Sources

Splits

  • datacite_only: normalized affiliations present only in DataCite (1194519 rows).
  • crossref_only: normalized affiliations present only in Crossref (32776285 rows).
  • overlap: normalized affiliations present in both sources (327249 rows).

Counts and integrity identities

  • DataCite source rows: 1521768.
  • DataCite occurrence count: 334586335.
  • DataCite raw affiliation count: 1681526.
  • DataCite DOI-affiliation pair count: 111934040.
  • Crossref source rows: 33103534.
  • Union rows: 34298053.
  • DataCite identity: 1521768 = 1194519 + 327249.
  • Crossref identity: 33103534 = 32776285 + 327249.
  • Union identity: 34298053 = 1194519 + 32776285 + 327249.

Per-row DataCite usage

Every output row has normalized_affiliation, datacite_occurrence_count, datacite_doi_count, datacite_raw_affiliation_count, has_valid_ror_id, valid_ror_id_count, valid_ror_assignment_occurrence_count, valid_ror_assignment_occurrence_share, valid_ror_assignment_doi_count, valid_ror_assignment_doi_share, invalid_ror_assignment_occurrence_count, invalid_ror_assignment_occurrence_share, invalid_ror_assignment_doi_count, invalid_ror_assignment_doi_share, ror_ids, most_common_ror_ids_by_occurrence, and most_common_ror_ids_by_doi. The DataCite measures carry normalized occurrence, distinct DOI-affiliation pair, raw-affiliation-row, and explicit ROR coverage values. DataCite measures are zero for crossref_only rows; their ROR values are false, zero, and empty lists.

Normalization

Membership uses the shared normalization contract, also recorded in overlap_metadata.json. Its ordered steps are:

  1. Unicode text is transliterated to ASCII with Unidecode.
  2. letters are converted to lowercase.
  3. punctuation is removed while internal whitespace is preserved.
  4. surrounding whitespace is trimmed; empty results are excluded.
