This paper introduces a Five-Aspect Model (5-S Model) of epistemic determination, extending the ontological framework of Existential Trialism (Gamboa 2026). It argues that structural descriptions alone are insufficient to account for meaning, contextual relevance, and qualitative appearance. By distinguishing the aspects of structure, system, semantics, sense, and sensibility, the model provides a layered account of how entities are constituted and accessed. It shows that meaning, relevance, and experience arise through irreducible modes of determination rather than from structure alone. The framework integrates ontology and epistemology and establishes a basis for analyzing natural and artificial systems. It further identifies sensibility as a distinct mode of determination, preparing the ground for a structural account of experience and its implications for artificial intelligence.
