On Pseudogapping in HPSG

Abstract

This study investigates the constraints imposed on the pseudogapping in the framework of Head-Driven Phrase Structure Grammar (HPSG). Based on the existing schema to account for coordination and gapping, a new pseudogapping schema in coordination structures is proposed in this paper. In the process of capturing the constraints, new DOM lists are added and an existing DOM list is divided into two DOM lists depending on the feature of elements in each domain. Futhermore, new features SEP and INC are introduced. SEP is used for distinguishing prepositions which should be located in the same domain with the following NPs from those which can be separated from the following NPs. INC feature determines whether overlapping adverbs are in non-empty lists or not. Pseudogapping occurs not only in coordination structures, but in comparative or subordination structures. Thus, this paper introduces a pseudogapping schema that can be applied to all structures mentioned above. (Seoul National University)
