YAMATO (Yet Another More Advanced Top-level Ontology)

What it is YAMATO is a foundational ontology built and maintained by Riichiro Mizoguchi, first created in 1999 and subsequently revised several times. The site provides browsable English content and downloadable Hozo and OWL files, both marked updated on 2021-08-09.

Key concepts Its highlighted features are theories of quality and quantity, representations or content-bearing things, and objects, processes, and events. The site also connects YAMATO to formal work on artifacts, biological functions, events, roles, and occurrents.

How you’d use it Use the downloadable ontology as a top-level foundation for domain modeling. The source reports applications in medical ontology development, learning and instructional theories, genomics, mobile-user behavior, and functional ontology.

LLM angle none stated

Pitfalls & lessons The site says its cited ontology of function and theory of roles are not reflected in YAMATO, despite being related work. Users should therefore distinguish the ontology’s included content from the broader theories listed around it.

Verdict A long-running upper-level ontology centered on three explicit theory areas and backed by reported use across several domain projects.
