OPENBIB Data: Curation of metadata from German research institutions in OpenAlex

About

The OPENBIB project, maintained by the Kompetenznetzwerk Bibliometrie,
provides access to curated OpenAlex data with a focus on the German research landscape.

Curated data is provided for following entities:

• Authors 👩‍🎓
• Publishers 📚
• Funding information 📄
• Document types 🗂️
• Address information 🏛️
• Transformative Agreements 📑️

Annual snapshots from the OPENBIB project are openly available to users of the Kompetenznetzwerk Bibliometrie, via the Open Scholarly Data Warehouse of the SUB Göttingen and Zenodo.

The current release is based on the August 2024 snapshot of OpenAlex, limited to works with publication years 2014 to 2024.

Usage

Address information

The following figure compares the assignment of publications to German institutions in OpenAlex and in OPENBIB. While OpenAlex combines rule-based and machine learning algorithms to match address affiliations in documents with institutions, OPENBIB applies a pattern matching approach. The figure only displays institutions that are present in both OpenAlex and OPENBIB and can be assigned a unique Research Organisation Registry (ROR) ID.

Fig.1: Publications assigned to German institutions in OpenAlex and OPENBIB based on ROR-Matching. Only publications published between 2014 and 2024 are considered.

Document types

The following figure compares the classification of article and reviews in OpenAlex and in OPENBIB. OpenAlex counts more article and reviews than OPENBIB, because OpenAlex also labels case reports, abstracts, book reviews and editorials as articles and reviews.

Funding information

The following figure compares the number of publications with funding information of the German Research Foundation in OpenAlex and in OPENBIB. Only publications funded by the German Open-Access-Publikationskosten program are considered.
