More open abstracts? Comparing abstract coverage in Crossref and OpenAlex
https://bmkramer.github.io/SesameOpenScience_site/thought/202411_open_abstracts/

The dataset contains the following files:

• abstracts_crossref_openalex_202410.csv
• abstracts_crossref_openalex_data_dictionary.txt

The csv file contains data on abstract coverage for Crossref DOIs in Crossref and OpenAlex, aggregated by publisher, for the top 1000 publishers in terms of number of retrieved dois. Scope is limited to publications with Crossref type 'journal-articles' and publication years 2022-2024. Variables are described in the data dictionary included in this record.

This analysis was performed using Curtin Open Knowledge Initiative (COKI) infrastructure, which is documented on GitHub: https://github.com/The-Academic-Observatory. Here, a number of open data sources (including Crossref, OpenAlex and OpenAIRE) are ingested into a Google Big Query environment, which can then be queried via SQL.

The following data sources were used:

• Crossref (Metadata Plus snaphot 2024-10-31, Crossref member route API 2024-11-20)

• OpenAlex (data snapshot 2024-10-30)

The code used to generate the dataset is available on GitHub: https://github.com/bmkramer/more_open_abstracts
