Abstract

In Korean dialogue honorification phenomenon may occur, an honorific pronoun may be used, and a subject or an object may be completely omitted when it can be recovered based on context. This paper proposes that in order to process Korean dialogue in which such distinct linguistic phenomena occur and to construct its representation structure we mark and use the following information explicitly, not implicitly : information about dialogue participants, information about the speech act of an utterance, information about the relative order of social status for the people involved in dialogue, and information flow among utterances of dialogue. In addition, this paper presents a method of marking and using such situational information and an appropriate representation structure of Korean dialogue. In this paper we set up Korean dialogue representation structure by modifying and extending DRT (Discourse Representation Theory) and SDRT (Segmented Discourse Representation Theory). Futhermore, this paper shows how to process Korean dialogue computationally and construct its representation structure by using Prolog programming language, and then applies such representation structure to spontaneous Korean dialogue to know its validity.

한국어대화에서는 존대현상(honorification phenomenon)이 일어나기도 하고, 존대대명사(honorific pronoun)가 사용되기도 하며, 맥락상 되찾을 수 있으면 주어나 목적어가 완전히 생략되기도 한다. 이러한 특징적인 언어현상이 일어나는 한국어대화를 처리하고 그것의 표상구조를 만들기 위해서 대화참석자에 관한 정보, 발화문의 화행에 관한 정보. 대화에 관련된 사람들의 사회적 지위에 있어서의 상대적 순위에 관한 정보, 대화에 나타나는 발화문 사이의 정보흐름 등을 묵시적으로가 아니라 명시적으로 표시하고 이용할 것을 본 논문은 제안한다. 또한. 본 논문은 이러한 상황정보(situational information)를 표시하고 이용하는 방법과 한국어대화의 적절한 표상구조를 제시한다. 본 논문에서 한국어대화표상구조의 설정은 담화표상이론(Discourse Representation Theory)과 분할담화표상이론(Segmented Discourse Representation Theory)을 수정ㆍ확대하여 이루어진다. 나아가서, 본 논문은 한국어대화를 전산적으로 어떻게 처리하고 그것의 표상구조를 구축하는지를 프롤로그 프로그래밍 언어를 사용하여 보여주고 나서, 그러한 표상구조의 타당성을 알아보기 위해 자연발생적 한국어대화에도 적용시켜 본다.
