Abstract

Korean auxiliary constructions are the most widely used constructions in the language. A theoretically and computationally feasible grammar of these constructions is thus a prerequisite to the successful development of any syntactic and semantic analyzers. This paper reviews some basic properties of these constructions and briefly discusses the merits of treating these constructions as a type of complex predicate. The paper then sketches this analysis within the framework of constraint-based grammar of Head-driven Phrase Structure Grammar (HPSG), the grammar which models human languages as systems of typed feature structures. Based on these empirical and theoretical observations, to test the efficiency of the grammar in a computational perspective, we implement this complex-predicate analysis into the Linguistic Knowledge Building (LKB) system, a grammar and lexicon development environment for use with constraint-based linguistic formalisms such as HPSG (cf. Coopstake, 2002). The result of this research proves that a constraint-based grammar wíth mathematically and precisely well-defined type-hierarchy systems can provide us plausible and efficient ways of building a theoretically sound, empirically proper, and computationally tractable Korean grammar
