contexteither

Contexteither is a theoretical construct used in linguistics and natural language processing to describe a modeling approach that explicitly allows two alternative contextual frames to jointly influence the interpretation of a linguistic unit. It is designed to capture how ambiguity can persist when two plausible contexts could determine meaning, and how downstream information might resolve that ambiguity.

The term is a portmanteau of context and either, signaling a binary contextual disambiguation mechanism. In discussions of context-sensitive semantics, contexteither offers a way to formalize competing interpretations by maintaining parallel context branches rather than committing to a single frame too early in processing.

In a formal framework, the contexteither model represents contexts as sets of constraints or features. An interpretation function then yields a pair of meanings, each tied to one branch of the context, along with traces of the contextual provenance. Disambiguation signals from later discourse, world knowledge, or probabilistic cues can then tip the balance toward one branch or, in some formulations, retain both meanings for downstream tasks such as translation or question answering.

Applications of contexteither appear mainly in theoretical discussions of polysemy and context-driven disambiguation, as well as in NLP pipelines that aim to delay premature resolution of ambiguity. It is also used in experimental psycholinguistics to model reading or listening where competing contexts influence processing time or extent of integration.

Example scenarios often involve lexical ambiguity such as bank or bat, where one branch aligns with a financial institution and the other with a physical object or animal habitat. The contexteither approach provides a structured way to represent and compare these competing readings until further information resolves the interpretation.
