Graph Statistics
To evaluate the quality and completeness of the Knowledge Graph, both core and linking statistics were collected. Core statistics measure the scale and density of information, while linking statistics highlight the degree of integration with external sources.
Core Statistics
- Total triples: ~92.5 million
- Classes: 16
- Predicates: 98
- Average relations per molecule: 9.2
Linking Statistics
The following table shows the share of instances connected via owl:sameAs:
| Class | Total Instances | With sameAs | Without sameAs | Share with Links |
|---|---|---|---|---|
| Molecule | ~1,000,000 | ~260,000 | ~740,000 | ~26% |
| Organism | ~53,000 | ~28,000 | ~25,000 | ~54% |
| GeoLocation | ~2,640 | ~240 | ~2,400 | ~9% |
These numbers provide insights into both the richness of the dataset and the degree of its interlinking with external Knowledge Graphs.
