COVID-19++: A Citation-Aware Covid-19 Dataset for the Analysis of Research Dynamics

COVID-19++ is a citation-aware COVID-19 dataset for the analysis of research dynamics. In addition to primary COVID-19 related articles and preprints from 2020, it includes citations and the metadata of first-order cited work. All publications are annotated with MeSH terms, either from the ground truth, or via ConceptMapper, if no ground truth was available. 

The data is organized in CSV files

- Paper metadata (paper_id, publdate, title, data_source): paper.csv

- Annotation data, mapping paper_id to MeSH terms: annotation.csv 

- Authorship data, mapping paper_id to author, optionally with ORCID: authorship.csv
- Paired DOIs of citing and cited papers: references.csv

The column data source within the paper metadata has the value KE (for metadata from ZB MED KE), PP (for preprints) or CR (for cited resources from CrossRef)
