Kim Kwang-hee. 2003. On the Semantic Constraints on the Binding of Absent Arguments in Korean. Korean Semantics, 12. This paper revisits a topic introduced very widely and thoroughly in Transformational Grammar, namely, Empty Category in the Korean language. In discussing this phenomena, we will expand the Empty Category to other syntactic concepts which are ellipsis and gapping. And we propose the way how to account for the unified these three categories - ellipsis, gapping, and PRO/pro - and how to analysis without the transformational mechanism. The solution to the untransformational theory, proposed here, is to use the constraints, as introduced into the field of HPSG by Sag and Wassow(1999). We will introduce lexical information - a bundle of Syntactic, Semantic, Situational Grammatical Information - which are mapping from lexical information and structure representations to phrase structure presentation that can explain the control and government as well as agreement and other syntactic phenomena.
