Gold Datasets of Verified Affiliation Strings with ROR Matches from zbMATH Open Publications

These datasets contain affiliation strings from zbMATH Open publications together with their corresponding Research Organization Registry (ROR) matches, intended to support research on affiliation disambiguation and institutional analysis in the mathematical research domain. The data were selected from zbMATH Open publications. The affiliation strings match institutions from different countries. Dataset g1 consists of the following columns: an: zbMATH publication identifier aff_str: the original affiliation string as it appears in the publication ror_ids: matched ROR identifier(s) for the affiliated organization ror_names: organization name(s) corresponding to the matched ROR identifier(s) Dataset g2 extends g1 with an additional column: an: zbMATH publication identifier aff_str: the original affiliation string as it appears in the publication ror_ids: matched ROR identifier(s) for the affiliated organization ror_names: organization name(s) corresponding to the matched ROR identifier(s) match_status: classification of the match result (see below) Each affiliation string in g2 was independently verified and classified using the following categories: TP (True Positive): the affiliation string is correctly matched with the corresponding ROR identifier and organization name FP_partial (False Positive – partial): the system identified a related but not exact organization FP_wrong (False Positive – wrong): the match is completely incorrect FN (False Negative): a valid affiliation that was missed by the matcher TN (True Negative): affiliations for which no ROR ID exists in the registry (as of the version used in this study) The match is considered correct if the aff_str matches the name of the exact organization or its parent organization. Note that aff_str may contain department names; however, the matcher currently identifies institute-level names only. It is important to note that repetition across subsequent rows may occur; this happens when multiple authors of a publication share the same affiliation. The zbMATH identifier (an) can be resolved via https://zbmath.org/ to obtain additional metadata, including DOIs. For example, an = 7199248 is associated with https://zbmath.org/7199248. The matching was carried out using a particular version of the Research Organization Registry (ROR). Consequently, some identifiers in the dataset may differ from those in the latest ROR release; however, earlier identifiers are automatically redirected to the corresponding current records in ROR. Possible applications include: Analyzing institutional contributions to mathematics research Studying author-affiliation patterns in mathematical publications Evaluating and benchmarking affiliation parsing and disambiguation methods Users are invited to contact the first author with suggestions or corrections. Future releases will extend the dataset with additional publication metadata, author-institution signatures, negative samples, and descriptive statistics.
