About Web Ontology Language · from Wikipedia

The Web Ontology Language (OWL) is a family of knowledge representation languages for authoring ontologies. Ontologies are a formal way to describe taxonomies and classification networks, essentially defining the structure of knowledge for various domains: the nouns representing classes of objects and the verbs representing relations between the objects.

  • ADS safety-testing ontology Key work
    ADS safety-testing ontology is an OWL ontology he built during his joint research at JAIST (the Japan Advanced Institute of Science and Technology) in 2025.
  • ask.chaipat.cc, the ask-me-anything site Key work Nov 2026
    The graph is written in RDF Turtle and described by a small OWL ontology of its own (the cj: vocabulary): the same kind of knowledge graphs he builds in his research, pointed at his own work.
  • Ontology-augmented health recommendation Key work Mar 2026
    It models healthcare in Thailand (diseases, symptoms, treatments, specialties, facilities and insurance) as an OWL 2 DL ontology, so a reasoner can recommend where a patient should go and what their insurance covers.
  • Ontology & SPARQL cheat sheets Mar 2026
    They come from the same term as his ontology-augmented health recommendation project, a course project in ontology engineering built on OWL and SPARQL.
  • Reasoner (ask.chaipat.cc)
    The reasoner in src/reason.js gives ask.chaipat.cc RDFS and OWL reasoning, property chains included: when the graph loads, it applies the site's OWL ontology to the facts and adds what they imply.
