The purpose of this paper is to analyze the lexical-semantic structure of morphologically derived passive verbs in Korean based on Pustejovsky (1995)'s Generative Lexicon Theory (GL) and to explain the change of the root verb's lexical-semantic structure by means of passivization. Passivization in this paper is defined as the unaccusaztivization. In Argument Structure of derived passive verbs, the agent argument is deleted and the theme argument is realized as a syntactic subject. As for Event Structure, derived passives express left-headed event (achievement), whereas their roots denote right-headed event (accomplishment). In Qualia Structure, passive verbs and root ones have the same Fomal Role, but in Agentive Role of passive verbs, an act weakens to a process. Both Formal and Agentive Roles have the same theme argument.

The prepositional object (PO) of an active sentence in English can sometimes be passivized, becoming the subject of the corresponding passive sentence. In particular, the verb (V) and preposition (P) in the English prepositional passive (P-Passive) are assumed to be reanalyzed to form a single structural unit, giving the status of a verbal object to the PO to be passivized. However, not every V+P sequence can undergo reanalysis, permitting the passivization of POs. Thus, we have to explain what licenses the reanalysis of V and p. resulting in an acceptable P-Passive sentence. In this paper, I will identify the factors which determine the passivization possibilities of POs and explain how they interact with one another. The results of this study will illustrate how formal and functional factors work together to form a major syntactic construction and to determine its grammaticality and acceptability.

Transitive relation and its directionality constitute the precondition for passivization, and the present study purports 10 unearth the true properties of transitivity in connection with the passive phenomena. The bottom line it drives at is this transitivity is a notion that can be best explained in 'cognitive' terms. The original direction of transitivity that is predicated by a verb can be reversed depending on the speaker's intention or the discourse situation. In the imperfective verb constructions transitivity can not be derived from only the content of the sentence itself and the predicate objectionally. That depends on the subjective interpretation of speaker considering the cognitive prototype of human to the various complicated situations.

The operation Move is defined in Chomsky (1999, 2000) as a composite operation consisting of three components: Agree, Identify and Merge, taking Agree as a necessary condition for Move. Therefore, I call this definition of Move as the Agree-based Move. In this paper, I argue that the Agree-based approach to Move cannot be maintained; I claim that the Selection-based approach to Move, in which the EPP-feature is analyzed as an s-selectional property of a head, offers a more natural account of the sentences under consideration. I believe that the three components of Move as defined in (6) happen to co-occur in the derivation of certain sentences, as the composite transformation called Passivization does in the derivation of a passive sentence like “the city was destroyed by the enemy.” On the basis of these observations, I conclude that Agree and Move should be regarded as separate computational operations; the task of Agree is to erase uninterpretable features of both probe and goal, and that of Move is to satisfy the EPP-feature, which should be taken as an s-selectional feature.

There are several English constructions in which a certain constituent appears to the left of its canonical position, typically sentence-initially, leaving its canonical position empty. Such constructions involve Left-dislocation and Y-movement. These operations are called ‘Preposing.’ The preposed constituent of such constructions is generally regarded as the topic of the sentence which involves that constituent. Topics must have at least two features; ‘aboutness’ and ‘givenness.’ The feature ‘aboutness’ defines the range of comment, and the feature ‘givenness’ means ‘informationally old or given.’ The purpose of this paper is to show that the function of Preposing is to reinforce the aboutness of the preposed constituent of a sentence and that most preposed constituents have givenness. We examined Preposing for this purpose. Tough-movement and Passivization were examined also, because they have characteristics informationally similar to those of Preposing.

ECM across a CP in Korean poses difficulties from the standpoint of the locality of A-movement/agreement. A phase-based analysis is developed which requires two steps: (i) in the embedded CP, VP/VP containing its VP-internal subject first moves to Spec-CP, which renders the subject accessible to the matrix v, in accordance with Chomsky's Phase Impenetrability Condition; (ii) ECM takes place in a local relation between the matrix v and the embedded subject. It is shown that the otherwise puzzling fact that ECM across a CP, but not Passivization across a CP, is affected by the type of the embedded verb in Korean is accounted for in a principled way, based on the assumption that CP and CP, but not TP and VP, are phases.

한국어와 일본어는 문법 체계의 유사성으로 인하여, 양언어의 형태소들 간에 1대1 매핑만으로도 높은 번역 성능을 얻을 수 있다. 따라서, 대부분의 한-일 기계번역에서는 한국어와 일본어 형태소 사이에 1대1 매핑을 기본으로 하고 있다. 명사와 '하다'로 구성되는 한국어 '하다' 용언도 대부분 명사와 'する'로 구성되는 일본어 'する 용언에 대응되므로, 일반적으로 1대1 매핑을 관계를 적용한다. 그러나, 한국어 '하다' 용언이 일본어 'する'용언에 대응되지 않는 경우, 1대1 매핑만으로는 정확한 번역 결과를 얻지 못하는 경우도 자주 발생하게 된다. 이 경우 명사와 '하다'를 하나의 번역 단위로 다루어 주는 것이 필요하다. 따라서, 본 논문에서는 한국어 '하다' 용언의 특성을 조사하고. 명사와 '하다' 사이에 삽입된 어휘들에 의한 비연속성 문제, 피동화, 관형어 수식 등 입력 문장에서의 다양한 상황에 따른 '하다'용언의 변환 기법을 제안하였다. 실험 결과, 높은 번역 성능을 보임으로써 제안한 방법이 한일 기계번역에서 '하다'용언을 다루는데 효율적임을 볼 수 있었다.
