한국어 대화에서는 상황에 따라 주어나 목적어가 대화 속의 발화문에서 완전히 생략되기도 하고, 존대현상이 일어나기도 하고, 존대대명사가 사용되기도 한다 본 논문은 이러한 특징적인 언어현상이 일어나는 한국어 대화를 처리하고 그것의 표상구조를 만들기 위해서는 대화참석자에 관한 정보, 발화문의 화형에 관한 정보, 대화에 관련된 사람들의 사회적 지위에 있어서의 상대적 순위에 관한 정보, 대화에 나타나는 발화문 사이의 정보흐름에 관한 정보 등을 명시적으로 표시하고 이용하여야 한다고 주장하며, 또한 이러한 상황정보를 한국어대화표상구조에 구현하는 방법을 제안한다. 본 논문에서 한국어대화표상구조의 구축은 담화표상이론(Discourse Representation Theory)과 분할담화표상이론(Segmented Discourse Representation Theory)을 수정, 확대하여 이루어진다.

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.

This paper explores Discourse Rep-resentation Structures which can successfully describe the mental representations that discourse participants form when they hear so-called double access sentences. The syntactic, semantic and pragmatic characteristics of double access sentences are discussed. The analysis proposed in this paper, employing a modified version of the 'conditional beliefs' of Chung(1997), successfully explains the semantic and pragmatic characteristics of present or future tense in double access sentences as well as when and why the speaker should take or can be exempted from the responsibility for using present or future tense in double access sentences.

This paper examines two different approaches to resolving a theoretical problem which the bottom-up approach version of Discourse Representation Theory of Kamp et al. (2003) faces in dealing with anaphoric relations between pronouns and their potential antecedents in conditional sentences where consequent clauses precede their corresponding conditional clauses. In one of the approaches, every element is processed in the order of occurrence and conditional operators in a non-sentence-initial position cause the ongoing DR to split in two with the same index. The definition of accessibility is accordingly modified so that the right DR can be accessible from the left DR. In the other approach, a different type of discourse representation structure, K ${\Leftarrow}$ K, is introduced, which allows us to resolve the target problem without modifying accessibility proposed in Kamp et al. (2003). Compatibility of these two approaches with the bottom-up version of DRT is evaluated by examining their applicability to the analysis of quantified sentences where pronominal expressions precede generalized quantifiers.

Since the introduction of Deep Neural Networks to the Natural Language Processing field, two major approaches have been considered for modeling text. One method involved learning embeddings, i.e. the distributed representations containing abstract semantics of words or sentences, with the textual context. The other strategy consisted of composing the embeddings trained by the above to get embeddings of longer texts. However, most studies of the composition methods just adopt word embeddings without consideration of the optimal embedding unit and the optimal method of composition. In this paper, we conducted experiments to analyze the optimal embedding unit and the optimal composition method for modeling longer texts, such as documents. In addition, we suggest a new discourse-based composition to overcome the limitation of the sequential composition method on composing sentence embeddings.

This paper proposes a dynamic approach to anaphoric resolution in conjunction phrases, in terms of Discourse Representation Theory. Unlike Kamp, van Genabith, and Reyle (forthcomming)'s analysis, it proposes two different types of discourse representation structures for conjunction phrases; one for coordinate phrases such as and conjunction phrases and the other one for subordination conjunction phrases such as when subordination phrases. Following Chung (1992), Chung (2004), every element is processed in the order of occurrence and conjunction operators in a non-sentence-initial position cause the ongoing DR to split in two with the same index. DRS conditions and accessibility are accordingly modified so that DRs for conjunction clauses can be accessible from DRs for main clauses.

본 논문은 동사의 의미표상과 명사의 한정성의 강호관계를 중심으로 목적어의 생략현상을 검토하였다. 한국어는 영어 같은 언어와 달리 주어, 목적어 등이 자주 생략된다. 이 연구는 한국어의 목적어 생략이 단순히 인간성 (humanness), 주체성 (agency), 한정성(definiteness) 등 명사의 의미자질에 의해서만 결정되는 것이 아니라, 다음 두 가지 제약이 결정적으로 작용함을 제안하고자 한다. 첫째, 목적어 생략은 행동양상 (mold of agent act)과 원인 (cause)을 심층적으로 포함하는 소위 '핵심 타동사 (core transitive)'와 선행사의 한정성 정도에 의해 결정되는데, 구체적으로 목적어 생략은 한정성 자질을 가진 선행사가 없는 담화에서는 허용되지 않는다는 제약이다. 둘째, 타동사와 명사의 한정성과는 독립적으로, 한국어의 목적어 생략은 또한, 추론에 의거하여 보다 더 적절히 해석될 수 있는 경우를 실증적으로 보이고자 한다.

Bei den vorigen Untersuchungen von VP-Ellipsen handelte es sich urn Auxiliarverben, die im elliptischen Satz auftreten und auf die Wiederherstellung der elliptischen VP bezogen sind. Im Unterschied dazu, geht es bei der vorliegenden Arbeit urn die Partikel auch, die in den VP-Ellipsenkonstruktionen auftritt. Zuerst spielt die Partikel auch als ein Fokusoperator eine Rolle, d.h. sie identifiziert das Subjekt des elliptischen zweiten Satzes als eine Fokuskonstituente und addiert die Fokusbedeutung der Fokuskonstituente. Zweitens spielt die Partikel auch als ein $Pr\"{a}suppositionsausl\"{o}ser$ eine Rolle. Hierbei behauptete ich, dass sie eine einfachere Proposition 'Jemand anders als das Subjekt des elliptischen zweiten Satzes existiert.' als in den vorigen Untersuchungen $pr\"{a}supponiert$. Aufgrund von oben genannten Beobachtungen $repr\"{a}sentierte$ ich im Rahmen von $Diskursrepr\"{a}sentationstheorie$ die Bedeutung der VP-Ellipsenkonstruktionen. Insbesondere, indem ich nach Kamp et al. (2003) zweistufige Prozedure von DRS-Konstruktionen annehme, konnte ich einzelne Bedeutungen der Partikel auch erfassen und beschreiben.

The main purpose of this paper is to investigate the effects of discourse topic and morpho-syntactic verbal information on the resolution of null pronouns in the Korean narrative text within the framework of the construction-integration theory (Kintsch, 1988, Singer & Kintsch, 2001, Graesser, Gernsbacher, & Goldman. 2003). For the purpose of this paper, two conditions were designed: an explicit condition with both a consistently maintained discourse topic and the person-specific verb modals on one hand, and a neutral condition with no discourse topic or morpho-syntactic information provided, on the other. We measured the reading tines far the target sentence containing a null pronoun and the question response times for finding an antecedent, and the accuracy rates for finding an antecedent. During the experiments each passage was presented at a tine on a computer-controlled display. Each new sentence was presented on the screen at the moment the participant pressed the button on the computer keyboard. Main findings indicate that processing is facilitated by macro-structure (topicality) in conjunction with micro-structure (morpho-syntax) in pronoun interpretation. It is speculated that global processing alone may not be able to determine which potential antecedent is to be focused unless aided by lexical information. It is argued that the results largely support the resonance-based model, but not the minimalist hypothesis.

Daehoon Ham's novel 'Cheongchunbo' features a studier as the main character who majored in Russian literature and admired the culture of the Soviet Union. From his viewpoint, the novel reproduces North Korean society before and after its independence from Japan. In this regard, it shows multilayered presence related to Russian culture and Soviet Russia. Such an aspect is based on the sense of sympathy that the main character has. The sense of sympathy is originated from the main character's admiration for the exoticism of Soviet culture which was forbidden during the late Japanese occupation. After Korea's independence from Japan, Russian was replaced by English. Such change also occurred in the main character's viewpoint. He underwent a change in his integrative viewpoint on Russian and Soviet under the name of Red Army. After defecting to South Korea, he began to put Russia down as a den possessed by the devil called 'communism.' In the meantime, Russia and Soviet have been separated from each other in ideological terms. The novel 'Cheongchunbo' stresses that the decisive cause of such changes is argued over trusteeship. The main character, fascinated by the presence of exotic Soviet, predicates that Soviet is a political symbol around the national division caused by the trusteeship. His change alluded to the life path of Korean authors who translated Russian literature after independence. During the Japanese occupation, Russian literature translated into Korea was a longing for forbiddance and admiration for Russia. However, the Russia presented in Daehoon Ham's novel before and after independence implies that the romantic translation has ended.
