Methodology, code and data source
The data sources, methodology and code used to produce this barometer are based on those of the Open Science Barometer proposed by the University of Lorraine, itself inspired by the French Open Science Barometer.
The data on publications from 2016 to 2020 for which at least one author is affiliated to the University of Strasbourg, are taken from extractions made in March 2021 from the following sites:
- HAL (API documented in French)
- Web of Science (API available under suscription, use the proxy to access to the database)
- PubMed (public APIs)
- Lens.org (API available under conditions)
APC data for the University of Strasbourg are not yet available.
The methodology used
After extraction, the data are cleaned following the method indicated by the University of Lorraine to obtain the list of Digital Object Identifiers (DOIs) of the University of Strasbourg publications 2016-2021.
This list is then enriched by the code of the French Open Science Barometer, which uses UnPaywall to add, in particular, the data indicating the status of each publication: open access (or closed), type of access (open archive, publisher, both).
The file obtained is finally completed by information from the Ministry of Higher Education dataset listing all publications with a French affiliation and Digital Object Identifier (DOI). This processing adds a scientific discipline to each publication.
The algorithm created by the Ministry was not always able to assign a discipline to each article; it will then indicate "unknown" in the "scientific field" column. To avoid displaying this category when viewing the open access rate by discipline, it has been added manually in the file for the University of Strasbourg publications of the year 2019 concerned.
Only publications with Digital Object Identifier (DOI) are taken into account by UnPaywall, which leaves out a certain number of publications, particularly in Social Science and Humanities (SSH).
The barometer code
The code used to produce this barometer is largely based on the code of the University of Lorraine, with some adaptations:
- addition of the graph representing the proportion of publications in open access since 2016
- adaptation of the data visualization according to the University of Strasbourg graphic charter
- addition of code
The code, the data and the queries are available on Gitlab.
