Bio2RDF Dataset Summary Statistics

Bio2RDF Release 3 Summary Statistics

For each Bio2RDF Release 3 Dataset, we compute summary statistics using SPARQL queries over the SPARQL endpoint with our script. You can browse the dataset descriptions and their statistics (e.g. Clinicaltrials) from the Release 3 Datasets.

We use a combination of the VOID vocabulary with our own custom vocabulary (described here). Each dataset is associated with its statistics using void:subset. Each statistics is typed using our custom vocabulary and has additional structure to describe its contents. We use YASGUI to execute the SPARQL queries [e.g. # triples for clinicaltrials]
