Open Ontologies: Tool-Augmented Ontology Engineering with Stable Matching Alignment
Open Ontologies is an open-source Rust-based system that combines LLM-driven ontology engineering with formal OWL reasoning and stable matching alignment. The research demonstrates that stable 1-to-1 matching is the critical factor for ontology alignment quality, achieving F1 scores competitive with state-of-the-art systems, while structured tool access via Model Context Protocol significantly outperforms raw file reading for LLM interaction.
