COVID19DS Dataset Version 4
5 years ago by
The Dice research group are happy to present version 4 of our Covid-19-related research publication dataset, dubbed COVID-19-DS. Our new version includes the following updates and new features:
- We added to our dataset all the newly added resources in the last releases of the CORD-19.
- Compared to the previous version, the dataset increased by 33%.
- The data is represented in one archive and it is no longer divided by three parts (commercial, non-commercial, custom license), as in the original data from the CORD-19.
- Bib entries were linked with papers using cvdo:hasPublication.
- Our publications were linked to MAKG Publications using owl:sameAs.
- The number of links increased respectively to other changes that had been applied (i.e., 400K+ more links).
- The ontology was expanded (see the UML class diagram of the Covid-19-DS Ontology below).
The following tables show the statistics between two versions (previous and current one):
