COVID19DS Dataset Version 4

21 days 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):
