Coordination and neutralization in HPSG

Abstract

In this paper, we use lattice theory to present an account of neutralization and coordination of unlikes that can easily be incorporated into current HPSG, where linguistic objects are modelled as totally well-typed, sort resolved feature structures. The account draws on the analysis of Levy 2001 and is consistent with the HPSG analysis of neutralization proposed by Levine et al. 2001. We show the essential properties required of a coordination/neutralization lattice, and argue that our analysis is the minimal lattice satisfying these requirements. The HPSG-based account of the same phenomena presented in Daniels 2001 of this collection is shown by lattice-theoretic methods to be essentially equivalent to ours.
