About Knowledge graph · from Wikipedia

In knowledge representation and reasoning, a knowledge graph is a knowledge base that uses a graph-structured data model or topology to represent and operate on data. Knowledge graphs are often used to store interlinked descriptions of entities – objects, events, situations or abstract concepts – while also encoding the free-form semantics or relationships underlying these entities.

  • ADS safety-testing ontology Key workOWL ontology that structures safety-testing knowledge for automated driving systems.
  • 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.
  • Knowledge-graph explorer Key work Apr 2026Graph Laboratory: a research workspace for exploring large system-of-systems datasets as force-directed graphs, built with Next.js, Postgres and Redis.
  • Knowledge graph construction from unstructured data Key work Feb 2025Pipeline that builds knowledge graphs from unstructured text: entity and relation extraction with spaCy, graph construction with NetworkX, export to edge lists, adjacency matrices and GraphML.
  • Ontology-augmented health recommendation Key work Mar 2026Ontology-augmented personal healthcare service recommendation for Thailand: an OWL 2 DL ontology of diseases, symptoms, services, facilities, locations and insurance, queried with SPARQL and reasoned over with SWRL rules. Built for an ontology-engineering course, with a full written report.
  • Claim Conflict Finder Oct 2026Agent skill that shows where research papers disagree and whether datasets, populations or methods explain it.
