Abstract

BFO case representation defeasible reasoning knowledge graph ontology OWL-DL professional ethics
Professional ethics boards in fields such as engineering must identify applicable obligations when multiple provisions of the same ethical code generate competing requirements. In prior work we defined a nine-component case representation for professional ethics analysis. This paper presents the ontological implementation of that representation, grounded in the Basic Formal Ontology (BFO) and classified through the Information Artifact Ontology (IAO). Type-level disjointness is verified by the Pellet OWL-DL reasoner. Three object properties (competesWith, prevailsOver, defeasibleUnder) expose the competition structure between obligations as asserted, SPARQL-queryable relationships between typed individuals. OntServe, an ontology server, instantiates the representation as a knowledge graph of case ontologies extracted from a professional board of ethics archive.
