최근 들어 온톨로지(ontology), 시소러스(thesaurus) 등과 함께 주목받고 있는 Princeton 대학의 워드넷(WordNet, 이하 PWN) 은 자연어 처리(NLP)와 관련하여 대안을 제시할 수 있는 어휘의미망(lexico-semantic network)이다. 또한 PWN을 기반으로 상이한 개별어 어휘의미망 구축이 여러 차례 시도되었고, 현재도 진행 중이다. 본 연구는 간접 구축 방식에 의한 어휘의미망 구축 시 요구되는 정제(refinement) 방식들을 검토하고, 이를 한국어 명사 어휘의미망(KL)에 적용하여 정확도 검증 방법의 한 대안으로 제시하였다. 또한 보다 정교한 정제 방법의 모색과 고찰은 향후 과제로 삼고자 한다.

In the area of natural language processing, a lot of unification-based grammar formalisms have been issued and are highlighted. The core of the formalisms is an unification of feature stutures. But few formal unification methodologies have been developed. Therfore, implementers of the formalisms could not help adopting an ad hoc design strategy for the unification module. In this paper, we suggest an efficient unification methodology using FUL, a programming language whic supports the unification. For the exeample, we will trace the unification processes in LFG and HPSG, the representative unification-based grammar formalisms, with FUL.

최근 인터넷의 보급은 사용자들에게 많은 다국어 정보를 제공하게 되었다. 그러나 정작 각 국가의 언어를 입력하기 위해서는 자주 자판세트를 변경해야만 하며, 각 국가별 자판 세트가 다르기 때문에 많은 입력 오류를 감수해야 한다. 이를 위해 본 연구진에서는 과거 한국어 환경에서 다국어 지원을 위한 많은 보조 환경을 구축하였으나, 언어 코드의 특성으로 인해 상세한 환경 설정은 전산 전문가의 도움을 통해야 했고, 언어 환경 구축 및 자판 세트 교정에 많은 어려움을 겪었다. 이러한 문제점을 해결하기 위해 본 연구에서는 XML을 이용하여 일반 윈도우기반 컨트롤에서 다국어 정보를 손쉽게 입력할 수 있는 XML DTD와 입력 보조 클래스를 개발하였다. 본 연구결과물을 이용할 경우 일반 언어전문가들이 자신만의 자판 입력세트를 손쉽게 구성할 수 있으며, 이를 운영하는 시스템의 크기도 매우 줄어들어, 전체적인 컴퓨터 운영 효율성을 상승시키는 효과를 거둘 수 있다.

영어와 한국어의 통사구조의 차이로 인하여, 이중언어자와 비이중언어자인 한국 대학생의 영어 문장 유형에 따른 통사 처리에 있어 차이가 있을 것이다. 네가지 영어 문장 유형, 수동태, 관계사절, 물주구문, 가정법 구문 등으로 문장 완성 과제를 실험하여 이중언어자와 비이중언어자의 문장완성 시간과 오류율을 측정하였다. 실험 결과 비이중언어자인 한국 대학생은 다른 문장 유형에 비하여 물주구문에서의 통사처리 수행에 있어 이중언어자와 유의한 차이를 보였다. 이로부터 이중언어자와 한국 대학생의 영어 문장의 통사 정보처리의 자동화 및 어순효과 정보와 생물 주어(word animacy)구문 단서, 즉 대부분의 주어는 살아있는 사물의 명사로 이루어져 있다는 단서(Gass, l987)의 사용에 대하여 논의하였다.

The purpose of this study was to develop a Korean infant-toddler developmental scale and to examine the demographic variables and infant-toddler development. The subjects were 167 mothers who have infant and toddler from 1 to 36 months of age in Seoul, Daejeon, Chungju, Yeasan, and llsan in Korea. The subscales consisted of language development, social and emotional development, physical development, and cognitive development. The significant variables which are influenced the infant-toddler development were age of infant-toddler and age of father.

The present study, focusing on the stress-shift constructions, examines the tendency of young children to give wrong wide scope interpretation in language acquisition and questions the validity of the guess pattern hypothesis argued by Grodzinsky & Reinhart (1993). According to the hypothesis, children know that they have to construct a reference-set, keep two representations in working memory, and check whether the interpretation needed in the given context justifies selection of competing reference sets, but their working memory is not big enough to hold the materials needed to complete the execution of this task. Hence they give up and resort to a guess. 1 carried out an experiment of 16 Korean children aged 3;9 to 6;2 to find out whether children have more difficulty in the interpretation of stress-shift constructions than of constructions with a nuclear stress, and therefore perform the interpretation of the former by guessing. Assuming that the tendency is caused by a deficiency in contextual computation rather than reference set computation, I try to explain it in terms of pragmatic considerations.

In this paper, we propose a Transformation-Based Learning (TBL) method on generating the Korean standard pronunciation. Previous studies on the phonological processing have been focused on the phonological rule applications and the finite state automata (Johnson 1984; Kaplan and Kay 1994; Koskenniemi 1983; Bird 1995). In case of Korean computational phonology, some former researches have approached the phonological rule based pronunciation generation system (Lee et al. 2005; Lee 1998). This study suggests a corpus-based and data-oriented rule learning method on generating Korean standard pronunciation. In order to substituting rule-based generation with corpus-based one, an aligned corpus between an input and its pronunciation counterpart has been devised. We conducted an experiment on generating the standard pronunciation with the TBL algorithm, based on this aligned corpus.

Technological advances in neonatology led to the improvement of the survival rate in preterm babies with very low birth weights. However, intraventricular hemorrhage (IVH) has been one of the major complications of prematurity. IVH is relevant to neurodevelopmental disorders, such as cerebral palsy, language and cognitive impairments, and neurosensory and psychiatric problems, especially when combined with brain parenchymal injuries. Additionally, severe IVH requiring shunt insertion is associated with a higher risk of adverse neurodevelopmental outcomes. Multidisciplinary and longitudinal rehabilitation should be provided for these children based on the patients' life cycles. During the infantile period, it is essential to detect high-risk infants based on neuromotor examinations and provide early intervention as soon as possible. As babies grow up, close monitoring of language and cognitive development is needed. Moreover, providing continuous rehabilitation with task-specific and intensive repetitive training could improve functional outcomes in children with mild-to-moderate disabilities. After school age, maintaining the level of physical activity and managing complications are also needed.

This discussion can be said to be a qualitative study on the possibility of linking communication education for college students and literacy education for Korean language-linked educators based on the theory of interpretation of cognitive meaning of media text containing complex mechanisms. The implicit meaning of media content expression used as an interactive communication strategy will be accepted as a multilateral interpretation according to the individual learner's cognitive environment. If so, how is the general media content meaning intended by the content creator being accepted? These doubts are the starting point for discussion. To solve the problem, I leaned on the experimental pragmatic methodology of cognitive aesthetics and applied a model of relevance of cognitive linguistics to connect learners' creative cognitive environment and present content to find a contrast. As a result of the discussion, it was possible to establish a basic framework for learners to express their subjectivity and creative thinking that could connect the cognitive environment and present content themselves. In particular, active and positive learners also revealed direct descriptive expressions to build a new cognitive environment, such as suggesting a third alternative to argue the ability to question produced media texts and the validity of the meaning implied in the text. In the future, since media text containing complex mechanisms is an indirect and persuasive communication behavior that occurs easily through various media in modern society, the universal communication principle of reliable conversation between media text creators and audiences should exist.
