Mapping bibliographic metadata collections: the case of OpenCitations Meta and OpenAlex
For researchers and practitioners working with open bibliographic metadata, this work provides a method to interlink large collections and identify inconsistencies.
This study maps entities between OpenCitations Meta and OpenAlex to integrate OpenAlex identifiers into OpenCitations Meta, revealing metadata consistency and accuracy issues.
This study describes the methodology and analyses the results of the process of mapping entities between two large open bibliographic metadata collections, OpenCitations Meta and OpenAlex. The primary objective of this mapping is to integrate OpenAlex internal identifiers into the existing metadata of bibliographic resources in OpenCitations Meta, thereby interlinking and aligning these collections. Furthermore, analysing the output of the mapping provides a unique perspective on the consistency and accuracy of bibliographic metadata, offering a valuable tool for identifying potential inconsistencies in the processed data.
