Dataset Configurations

Configuration Details

doi_author_affiliations

Flattened author-affiliation pairs extracted from DataCite records. Each row represents one author-affiliation relationship.

Schema:

• —doi (string): The DOI of the work
• —author_idx (int): Index of the author within the work
• —author_name (string): Name of the author
• —affiliation_idx (int): Index of the affiliation for this author
• —affiliation (string): Raw affiliation string
• —affiliation_hash (string): MD5 hash of the normalized affiliation string

enriched_records

Original DataCite records enriched with ROR IDs where matches were found.

Schema:

• —doi (string): The DOI of the work
• —creators (list): List of creator objects with nested affiliation data including matched ROR IDs

ror_matches

Successful affiliation-to-ROR matches.

Schema:

• —affiliation (string): Raw affiliation string
• —affiliation_hash (string): MD5 hash of the normalized affiliation string
• —ror_id (string): Matched ROR ID

ror_matches_failed

Affiliations that could not be matched to a ROR ID.

Schema:

• —affiliation (string): Raw affiliation string
• —affiliation_hash (string): MD5 hash of the normalized affiliation string
• —error (string): Reason for match failure

unique_affiliations

List of all unique affiliation strings found in the dataset.

Schema:

• —affiliation (string): Raw affiliation string

existing_assignments

Pre-existing ROR assignments found in DataCite records. Each row represents one author-affiliation-ROR relationship that was already present in the source data.

Schema:

• —doi (string): The DOI of the work
• —author_idx (int): Index of the author within the work
• —author_name (string): Name of the author
• —affiliation (string): Raw affiliation string
• —ror_id (string): Pre-existing ROR ID in the DataCite record
• —ror_name (string): Name of the ROR organization

existing_assignments_aggregated

Aggregated view of pre-existing ROR assignments, grouped by affiliation string and ROR ID.

Schema:

• —affiliation (string): Raw affiliation string
• —affiliation_hash (string): MD5 hash of the normalized affiliation string
• —ror_id (string): Pre-existing ROR ID
• —ror_name (string): Name of the ROR organization
• —count (int): Number of occurrences of this affiliation-ROR pair

disagreements

Cases where the newly matched ROR ID differs from a pre-existing ROR assignment, or where multiple conflicting ROR IDs exist.

Schema (type="match"):

• —type (string): "match" - disagreement between new match and existing assignment
• —affiliation (string): Raw affiliation string
• —affiliation_hash (string): MD5 hash of the normalized affiliation string
• —existing_ror_id (string): Pre-existing ROR ID in DataCite
• —existing_ror_name (string): Name of existing ROR organization
• —existing_count (int): Occurrences of this existing assignment
• —matched_ror_id (string): Newly matched ROR ID
• —matched_ror_name (string): Name of newly matched organization

Schema (type="user"):

• —type (string): "user" - multiple conflicting user-submitted ROR IDs
• —affiliation (string): Raw affiliation string
• —affiliation_hash (string): MD5 hash of the normalized affiliation string
• —ror_ids (list): List of conflicting ROR assignments with counts

Usage

from datasets import load_dataset

# Load successful ROR matches
matches = load_dataset("cometadata/datacite-affiliations-matched-ror", "ror_matches")

# Load author-affiliation pairs (large dataset, use streaming)
affiliations = load_dataset(
    "cometadata/datacite-affiliations-matched-ror",
    "doi_author_affiliations",
    streaming=True
)

# Iterate over records
for record in affiliations["train"]:
    print(record["doi"], record["affiliation"])
    break
