John Beavers: Towards A Semantic Analysis of Argument/Oblique Alternations in HPSG

I examine the semantic contrasts exhibited by argument/oblique alternations (argument realization alternations where one or more participants may be realized either as a direct argument or an oblique). Previous HPSG accounts of these have proposed that alternating verbs are ambiguous, where each variant has a structured semantics that makes different participants more or less structurally prominent in the semantic representation. I argue that such accounts fail to capture the full richness of the contrasts exhibited by such alternations, and propose instead a model that derives alternations from the lexical entailments each verb associates with the alternating participant.
