Ontology Design — Formal Knowledge Structure for Your Domain

I will design a formal ontology for your domain — defining entity classes, subclass hierarchies, properties with domain and range constraints, and relationship types using OWL or a property graph model, producing a knowledge representation that supports reasoning, inference, and consistent classification across your domain. Ontology design for AI applications requires balancing formal completeness with practical usability — an ontology that is too abstract fails to capture domain-specific nuances, while one that is too specific becomes unmaintainable as the domain evolves; a well-designed ontology at the right level of abstraction serves both inference requirements and practical maintenance needs.

The design covers entity class hierarchy with subclass relationships, property definition with domain and range constraints, relationship type formalisation, ontology documentation, validation against your priority query patterns, and a maintenance guide for ontology extension.
