Defineirt

Defineirt is a theoretical framework for managing how terms and their definitions are created, tested, and revised in dynamic knowledge systems. It addresses definitional drift, the tendency for meanings to shift as new data and contexts arise, by providing a formal method for updating definitions while preserving coherence.

At its core, defineirt identifies three components: a kernel definition that specifies the essential characteristics of a term, extension rules that govern permissible applications, and a contextual boundary that marks the domain where the definition applies.

The framework operates through an iterative cycle. A candidate definition is proposed, its implications are evaluated against observed data and use cases, and revisions are proposed according to predefined stability and adaptability criteria.

Applications include knowledge graphs, semantic search, taxonomy maintenance, and AI systems that rely on stable ontologies. Defineirt offers a structured approach to governance, versioning, and decision criteria for accepting, updating, or retracting terms.

Challenges include subjective judgments in choosing kernels, computational overhead, and potential disputes between communities. Proponents argue that transparent revision processes improve interpretability and resilience of semantic systems.

Relation to related concepts includes definitional drift, dynamic semantics, and ontology engineering. Defineirt remains a topic of ongoing discussion in theoretical and applied semantics, with no universal standard.
