Evaluation for kg-enp
Evaluator: Automated Evaluation
Evaluated on: 2026-01-06
⚠️ Automated Evaluation: This evaluation was generated automatically using an AI-based system. It is distinct from manual evaluations curated by human experts. Please review findings carefully and report any inaccuracies.
Evaluation Criteria: This evaluation uses the KG-Registry evaluation rubric as described in Cortes et al. (2025) . The rubric assesses knowledge graphs across multiple dimensions including access, provenance, documentation, maintenance, and fitness for purpose.
Access Level and Types
| Question | Answer | Comment |
|---|---|---|
| Access to data outside of the knowledge graph | Y | ENP portal at enpkg.commons-lab.org provides web-based access to experimental natural products |
| API or online access to the knowledge graph | N | Web portal available but no documented programmatic API for automated queries |
| Multiple access options available | N | Single web interface; no downloads, SPARQL, or alternative access methods documented |
| Source code availability | Y | Complete source at github.com/enpkg/enpkg_full for community development and research |
| Downloadable knowledge graph | N | No bulk dataset download; portal is primary access point |
Section Score: 2/5
