본 논문에서는 한국어 문장의 구조를 파악하는 데에 결정적인 역할을 하는 조사에 대한 정보를 보다 적극적으로 이용하는 파싱 방법을 기술한다. 이러한 방법을 실현하기 위하여 용언을 세밀하게 분류하였으며, 이를 바탕으로 문장의 형태를 분류하고 이 문장 형태에 필수적으로 나타나는 명사구의 문법적 역할을 파악하는 방법을 이용한 파싱을 시도하였다. 또한, 내부적으로는 언어학적인 틀에서 크게 벗어나지 않는 범위 내에서 약간의 경험지식을 동원하였다. 이를 구현함에 있어서 문법의 수준에서 파싱을 직접 제어하기 위하여 조건단일화 파싱을 사용하였다. 본 논문에서 제시한 파싱 방법은 분석의 초기에 불필요한 가지를 전지함으로써 결과 트리가 간략해져 복잡한 문장의 모호성을 상당두분 제거할 수 있게 해준다.

본 논문은 단락의 자동 구분을 통해 중요한 문장을 추출하는 요약 시스템을 제안한다. 먼저 어휘의 재출현 여부를 파악하여 어휘의 일치도와 어휘의 역할 변화와 같은 재출현 어휘의 양상 정보를 수집하고, 이를 통하여 문장 간의 긴밀도를 정량적으로 계산한다. 다음으로 측정된 문장간 긴밀도를 이용하여 사용자의 추출 범위에 따라 단락을 구분하고, 각 단락의 대표 문장을 선정하여 최종 요약문을 추출한다. 제안한 방법은 문서 제목, 문장의 위치, 수사 구조 등의 정보를 이용하지 않기 때문에 수사 구조가 자주 발견되지 않는 문서에도 적용이 가능하다.

In this paper, phrase boundaries in sentence are predicted and a phrase break information is applied to an HMM-based Korean Text-to-Speech synthesis system. Synthesis with phrase break information increases a naturalness of the synthetic speech and an understanding of sentences. To predict these phrase boundaries, context-dependent information like forward/backward POS(Part-of-Speech) of eojeol, a position of eojeol in a sentence, length of eojeol, and presence or absence of punctuation marks are used. The experimental results show that the naturalness of synthetic speech with phrase break information increases.

This research examined the development in Korean children of the comprehension of complex sentences. The relative difficulty in comprehension of the temporal conjunctions "before" and "after" was investigated. The order of mention, contextual support, and syntactic appearance was controlled. The role of cognitive strategies and developmental changes in the comprehension of these conjunction was included in this study. Subjects were 90 preschool children between 3 and 5 years of age. The task was a sentence-picture matching problem having 3 types of sentences combining temporally with "before" or "after". The results were that developmental changes in comprehension of the temporal conjunctions "before' and "after" in Korean children depended on the order of mention, contextual support, and such syntactic factors as the position of the subject of the sentence. The importance of the consistency in the occurrence of events and the order of mention in the acquisition of complex sentences among Korean children is similar to the acquisition of complex sentences in other languages.

This study examines the phonetic realizations of English word stress to identify the influence of experiment method on experiment results. Stimuli uttered by native and Korean ESL beginners in authentic conversations are extracted to be shuffled according to their positions in utterances and information structure. Results indicate that the acoustic characteristics of English word stress are realized depending on its position in utterances. The native speakers correlate the stressed syllables in shorter duration with higher pitch and stronger intensity at sentence-final positions unlike the previous experiments and the traditional definition that stressed syllables are uttered in longer duration with higher pitch and stronger intensity; at sentence-medial positions, the native speakers correlate the stressed syllables in longer duration with higher pitch and no regularity in intensity or in shorter duration with lower pitch and intensity depending on their conversational intention. Korean ESL beginners correlate the stressed syllables in shorter duration regardless of positions in sentences with no regularity in pitch and intensity. This study, thus, shows that a different experiment method may result in different results on the phonetic realizations of English word stress.

Skilled typists can type characters or words without looking at keyboard, relying on the finger's relative position. If the relative positions of the fingers can be identified, a virtual keyboard may be accomplished by applying the concept of "DataGlove" or "FingerRing". The virtual keyboard may be efficient as a new mobile input device supporting QWERTY keyboard layout. For the purpose of investigating skilled typing pattern, in this paper the touch-positions of the fingers are measured with a touchscreen while five skilled typists type a long sentence. From these measurements it can be observed that the groups of touch-positions are classified into alphabet characters. Though there are some overlapped groups we can find constant distances capable of being discriminated among the groups from investigation of the change of touch-position for touch-time. Based on the analysis, the prediction algorithm of the constant distance is proposed and evaluated, which is useful for realization of a portable virtual keyboard.le virtual keyboard.

Frequency adverbs can be interpreted as an adverb of quantification, and also as a frequentative adverb. These interpretations are related to the frequency adverbs' distributions, and the relation between semantics and syntax of frequency adverbs can be observed more explicitly when they appear with some other expressions in a sentence. Two frequency adverbs in Korean, cacwu and cakkwu, which seem to mean 'often/frequently', will be dealt with. We will specify their syntactic position by their interpretations derived from the relative ordering with other elements.

The study on the intonational characteristics is concentrated on the lowering of the pitch level that is described as declination and downstep. The Taegu dialect, which has phonological accentual system, has these phonetic characteristics in affirmative sentences or Yes-No Question sentences. But there is the opposite phenomenon in WH question sentences in Taegu dialect. When the accent of interrogative word in the sentence intial position is LHL, intonation pattern shows a continuous upward movement, indicating that intonation pattern of Taegu dialect is influenced by not only grammatical system but also accentual system.

This paper investigated -eullanjira sentence as a kind of construction of the Southwestern dialect in Korea. Five informants were selected to form the main corpus of -eullanjira. Through analyzing the corpus, its semantic, syntactic and morphological characteristics were figured out. Firstly, a view of construction grammar was adopted to capture the semantic and syntactic characteristics of -eullanjira. The construction of -eullanjira was established as "Xdo Yeullanjira Z". Syntactically, -do was found to be a common auxiliary particle, which allowed nouns, adverbs, verbs and adjectives to appear at the position of X, while only verbs and adjectives could appear at the position of Y. Subject-honorific, causative and passive prefinal endings could coexist with Y, while tense and modal prefinal endings could not. Z was an embedded clause, which had the semantic feature of [-DOUBT], meaning 'it should be done undoubtedly'. The formation of -eullanjira was next examined both diachronically and synchronically. It was found there was a conjuntive ending of Middle Korean, corresponding -eullanjira, namely, -landai. Finally, -eullanjira was newly analyzed as [[-eulla-]+[-n-ji-ra]].

본 연구는 문장 표상형성 과정에서 통사적 제약과 화용적 제약이 시간경과에 따라 각 구성성분의 표상 및 기억접근에 어떠한 영향을 미치는지를 살펴보고자 실시되었다.통사적 제약과 화용적 제약을 분리시키기 위해 구성성분의 통사적 역할(주어,목적어)과 언급순서(첫째,둘째)를 조작하였고, 문장 구성성분의 표상강도를 기억접근의 용이서을 통해 살펴보기 위해 각 문장을 마디별로 제시한 후 목표단어의 재인 반응시간을 측정하였다. 탐사재인의 지연시간이 255ms인 실험 1에서는 주어가 목적어보다 그리고 먼저 언급된 정보가 나중에 언급된 정보보다 각각 28ms씩 기억접근 시간이 빠르 것으로 나타났으나,지연시간이 1540ms으로 기렁진 실험2에서는 주어와 목적어간의 기억접근 시간의 차이는 없었고 먼저 언급된 정보가 나중에 언급된 정보에 비해 기억접근 시간이 48ms가 빠른 것으로 나타났다.따라서 통사적 제약과 화용적 제약 모두 문장 표상형성 과정의 초기에는 독립적인 효과를 미치나 일정시간이 경과하면서 통사적 제약의 효과는 사라지며 화용적 제약의 효과만 남는다고 할수 있다.본 연구의 이러한 결과는 문장의 기억표상이 중다제약의 수렴적 만족에 으해서 점진적으로 심성모형을 형성하는 과정이라는 이론적 입장을 지지한다.
