differenceus

Differenceus is a theoretical construct used in linguistics and philosophy to analyze how context shapes interpretation. It characterizes the difference between the semantic representation of an utterance as heard in different situational frames, capturing how meaning shifts with audience, purpose, and surrounding discourse.

Origin and terminology: The term is a neologism combining “difference” with the suffix “-us,” and it has appeared in pragmatics and contextual semantics discussions since the early 21st century. It is not a single formal theory but a family of context-sensitive approaches to meaning, designed to highlight how interpretations vary with context.

Conceptual framework: A differenceus model treats meaning as dependent on context. A difference function D(U, C1, C2) yields the change in interpretation of utterance U when moving from context C1 to context C2. Differences reflect factors such as presupposition, implicature, reference shift, and stance, and are intended to be measurable or at least comparable across settings.

Applications: The concept has been explored to compare translations and paraphrases, study discourse dynamics, and improve natural language processing by incorporating context-aware representations. It provides a framework for analyzing contextual drift in meaning across languages, genres, and communicative intents.

Criticism and limitations: Some scholars argue that “difference” is too diffuse for precise modeling and risks conflating related but distinct phenomena. Operationalization requires explicit context definitions and feature selection, which can complicate replication and cross-study comparison.
