Note: This repository is under active development for v3.00 (planned Fall 2026). The current public release is v2.50. Download the v2.50 OWL files from kbpedia.org/resources/downloads/.
This repository contains the source files and build artifacts for the KBpedia knowledge graph: CSV build inputs, typology files, external source mappings, properties, and versioned archives of prior releases.
It is intended for developers and researchers who want to understand, build upon, or contribute to the KBpedia knowledge graph construction process.
If you want to use KBpedia rather than build it, download the compiled OWL files directly from the KBpedia website:
- KBpedia Reference Concepts:
kbpedia_reference_concepts.owl - KBpedia Knowledge Ontology:
kko.owl
Download page: https://kbpedia.org/resources/downloads/
The OWL files are not stored in this repository due to their size (~150 MB). They are built from the source files here using the cowpoke roundtripping package.
