본 연구에서는 사전의 뜻말이에서 의미 정보를 추출하고, 이 의미 정보를 확률 통계적 방법에 적용하여 의미 중의성을 해결하는 모델을 제안한다. 사전의 뜻풀이말에 동형이의어를 포함하고 있는 표제어와 뜻풀이말을 구성하는 보통 명사, 형용사와 동사를 의미 정보로 추출한다. 비교적 중의성이 자주 발생하는 9개의 동형이의어 명사를 대상으로 실험하였다. 학습에 이용된 데이터로 정확률을 실험하는 내부 실험의 결과, 체언류(보통 명사)와 용언류(동사, 형용사)의 가중치를 0.9/0.1로 주는 것이 가장 정확률이 높았다. 외부 실험은 국어 정보베이스와 ETRI 코퍼스를 이용하여 1,796문장을 실험하였는데, 평균 79.73%의 정확률을 보였다.

To investigate how personality test items are understood by participants, their semantic representations were explored by Latent Semantic Analysis, In this thesis, Semantic Similarity Matrix was proposed, which contains cosine similarity of semantic representations between test items and personality traits. The matrix was compared to traditional factor loading matrix. In preliminary study, semantic space was constructed from the passages describing the five traits, collected from 154 undergraduate participants. In study 1, positive correlation was observed between the factor loading matrix of Korean shorten BFI and its semantic similarity matrix. In study 2, short personality test was constructed from semantic similarity matrix, and observed that its factor loading matrix was positively correlated with the semantic similarity matrix as well. In conclusion, the results implies that the factor structure of personality test can be inferred from semantic similarity between the items and factors.

This study is a preliminary work in examining how to manage resources for collaboratively interactive help systems. The purpose of this article is to describe significant patterns of behaviors and cognitive state in collaborative problem-solving situation, and further to explore the relationship between the behavior and the perception of service evaluation. Based on the concept of 'cognitive motion' in Dervin's Sense-Making theory, this study conducted a time-line interview. The sample of this study consists of 22 IT personnel helping other person solve IT problems and 36 users being helped for a IT problem-solving. This study presents a model of collaborative problem-solving behaviors and discusses some implications for designing help systems which collaborative interactions can happen.

치매(dementia)는 라틴에게서 유래된 말로서 '정신이 없어진 것' 이라는 의미를 갖고 있다. 태어날 때부터 지적 능력이 모자라는 경우를 정신지체(mental retardation)라고 부르는 반면, 치매는 후천적인 뇌질환이다. 즉, 정상적으로 생활해 오던 사함이 후천적인 뇌 손상으로 인하여 기억력, 언어능력, 방향감각, 판단력 등의 인지기능을 잃어가는 것이다. 또한 이런 인지 기능 장애가 심각하여 일상생활에 상당한 지장이 나타날 때 치매라고 한다.

Previous studies on the effect of incidental semantic priming on judgment, have focused mainly on mutually exclusive hypotheses. However, the present study explored whether incidental semantic activation affects diagnostic inference depending on the type of the hypothesis: mutually exclusive hypotheses vs compatible hypotheses. In Experiment 1, in case of mutually exclusive hypotheses, the final hypothesis was selected according to the incidental semantic priming, but there was no difference in the number of generated hypothesis in comparison with the control. However, for compatible hypotheses (i.e., both hypotheses can be true), the semantic priming affected the number of generated hypotheses, but not the selection of the final hypothesis. The same pattern of results was observed even when the cognitive load was increased. In Experiment 2, we found a boundary condition of incidental semantic activation on diagnostic inference. When cues related to each of the hypotheses were presented simultaneously, the incidental semantic effect disappeared. These results suggest that people consider all possible cues when making diagnostic inference in daily life. In light of these findings, further research on hypothesis generation/evaluation should take the type of hypothesis into account.

높임법의 최소형 정립은 말본범주의 인지뿐만 아니라, 사전의 어휘항복 설정에 절대적 중요성을 갖는다. 굴곡가지의 높임법 낱덩이, 곧 최소형 인지의 요건은 첫째, 분포상 굴곡가지가 줄기에 직접 통합되어야 한다는 것이며, 둘째, 줄기에 직접 통합되는 요소가 높임법의 의미를 가져야 한다는 것이다. 단순형태소가 줄기에 직접 통합하여 존대의 의미를 가지는 것은 홑최소형이 되고, 다른 것과 의무적으로 통합하여 줄기에 직접 통합되는 것은 겹최소형이다. 의무적인 겹최소형이 다시 독립적으로 설 수 있는 비의무적 요소와 통합하여 새로운 존대의 의미를 생성한다면, 이 또한 겹최소형이 된다. 높임의 최소형은 높임법과 의항법의 이차원의 성격을 띤다. 따라서 높임의 최소형의 전 분포는 높임의 등분과 함께, 의향법 체계에 걸쳐 있다. 최소형은 풀이씨의 종류에 따라 다름도 주의할 일이다. 시상법은 높임법의 구성소일 뿐이며, 또한 그 자체 독립하는 것으로 높임법과 의향법과는 그 차원을 달리한다.

The interpretation of noun sequence is to find semantic relation between the nouns in noun sequence. To interpret noun sequence, semantic knowledge about words and relation between words is required. In this thesis, we propose a method to interpret a semantic relation between nouns in noun sequence. We extract semantic information from an machine readable dictionary (MRD) and corpus using regular expressions. Based on the extracted information, semantic relation of noun sequence is interpreted. And. we use verb subcategorization information together with the semantic information from an MRD and corpus. Previous researches use semantic knowledge extracted only from an MRD but our method uses an MRD. corpus. and subcategorizaton information to interpret noun sequences. Experimental result shows that our method improves the accuracy rate by +40.30% and the coverage rate by + 12.73% better than previous researches.

The concept of frame in semantics has implications for our understanding of such problematic terms as "meaning" and "concept". It is conventional to say that a particular word corresponds to a particular "concept" and to assume that concepts are essentially identical across speakers. In contrast, the notion of frame accepts that the frame for a particular word can vary across speakers as a function of their particular life experience. To say, instead of thinking in terms of words as expressing "concepts", we should think of them as tools, like frames, that cause listeners to activate certain areas of their knowledge base, with different areas activated to different degrees in different contexts of use. This notion is Fillmore's most crucial contribution to current cognitive linguistic theories, and his frame semantics is built on such a notion. This paper discusses the basic assumptions and goals of frame semantics, and examines the notion of frame and illustrates various framing words of English and Korean under such a notion.

경영활동에 있어서 직관력은 잘 알려진 인지능력이지만 효과적인 의사결정지원시스템의 개발 목적으로는 거의 고려되고 있지 않다. 본 연구는 의사결정자의 인지 유형에 따른 시계열 예측의 정확성과 뇌파의 차이를 통계적 검증, 인공신경망, 데이터 마이닝의 세 가지 접근방법으로 탐색하여 그 결과를 비교 분석함으로써 시계열 직관 예측에 영향을 주는 의사결정자의 인지적/생리적 특성을 도출함으로써 효과적인 의사결정환경을 조성하는데 공헌하고자 하였다. 실험결과 통계적 분석에서는 아무런 유의성을 찾을 수 없었으나, 인공신경망 분석에서는 인지유형과 감성유형이 모두 시계열 예측 정확도와 상관성이 있는 것으로 나타났으며, 데이터 마이닝 분석에서는 보다 의미 있는 상관관계를 찾아낼 수 있었다.

In this article, I show that the cognitive suicide argument does not succeed in refuting eliminativism. The argument misses an important aspect of eliminativism. In Sec. 3, the last section, I will suggest the aspect of eliminativism and, on the basis of it, will develop my criticism against eliminativism.
