Retrieving relevant information well corresponding to the user`s request from web is a crucial task of search engines. However, most of conventional search engines based on pattern matching schemes to queries have a limitation that is not easy to provide results corresponding to the user`s request due to the uncertainty of queries. To overcome the limitation in this paper, we propose a framework for knowledge-based semantic meta-search engines with the following five processes: (i) Query formation, (ii) Query expansion, (iii) Searching, (iv) Ranking recreation, and (v) Knowledge base. From simulation results on english-based web documents, we can see that the Proposed knowledge-based semantic meta-search engine provides more correct and better searching results than those obtained by using the Google.

Purpose: The purpose of this study was to explore the experiences of Tai Chi in women with osteoarthritis. Methods: Data were collected by face-to-face interview from 14 participants. Theoretical sampling was performed until the concepts were saturated. The main question was "How do you describe your experience of Tai Chi?" Data were analyzed using a grounded theory methodology. All interviews were audio taped and transcribed verbatim. Results: The Phenomenon is 'QI flowing'. The core category was identified with 'inspiring one's life with strength'. This series of processes was categorized into four stages: 'Challenging Tai chi', 'Doing one's best', 'Deplenishing (the word used in English and Tai chi is emptying one's mind) one's mind', 'Taking a Positive view of life'. Conclusion: The finding of this study will offer profound understanding about the reported tai chi's experience. Additional research should be done as to the role of Tai chi as a nursing intervention strategy for osteoarthritis patients.

An eye-tracking experiment was conducted to examine resolving processes of grammatical marking ambiguities of Korean. and to evaluate predictions from the garden-path model and the constraint-based models on the processing of Korean morphological information. The complex NP clause structure that can be parsed according to the minimal attachment principle was compared to the embedded relative clause structures that have one of the nominative marker (-ka), the delimiter (-man, which roughly corresponds to the English word 'only'), or the topic marker (-nun) on the first NPs. The results clearly showed that Korean marking ambiguities are resolved by the minimal attachment principle, and the topic marker affects reparsing procedures. The pattern of eye fixation times was more compatible with the garden-path model, and was not consistent with the predictions of the constraint-based accounts. Suggestions for further studies were made.

This paper sets forth the phenomenon of Contrastive Reduplication (CR) in English relevant to the notion of contrastive focus (CF). CF differs from other reduplicative patterns in that rather than the general intensive function, denotation of a more prototypical and default meaning of a lexical item appears from the reduplicated form resulting as a semantic contrast with the meaning of the non-reduplicated word. Thus, CR is in concordance with CF under the concept of contrastivity. However, much of the previous works on CF associated contrastivity with a manufacture of a set of alternatives taking a semantic approach. We claim that a recent discourse-pragmatic account takes advantage of explaining the vague contrast in informativeness of CR. Zimmermann's (2006) Contrastive Focus Hypothesis characterizes contrastivity in the sense of speaker's assumptions about the hearer's expectation of the focused element. This approach makes possible adaptation to CR and recovers the possible subsets of meaning of a reduplicated form in a more refined way showing contrastivity in informativeness. Additionally, CR in other languages along with similar set-limiting phenomenon in various languages will be introduced in general.

The present paper investigates a particular structure in Taiwan Mandarin, "(NP) + (intensifier) + $gei^3ta^1$ "give him/it"+ adjective" in terms of construction grammar. The structure is mostly observed in utterances of younger generation. Though it is not regarded as a grammatical or standard structure, it is still a register of language. The structure lays emphasis on speaker's attitude toward an undesired, unpleasant event. In most cases, the attitude tends to be negative. The events or propositions must have existed or been completed. The adjectives compatible with this structure belong to category of higher degree. The grammatical usage illustrates semantic bleaching of $gei^3ta^1$. And the changes from giving to a grammatical particle denoting subjective belief is a kind of subjectification. Moreover, $ta^1$ could refer to events or situation expressed by a more complicated grammatical structure, or denotes nothing as a dummy word. Though many previous studies paid attention to the newly developed structure resulted from language contact, the adequate account was not provided. It is hoped through this investigation, we will get a better understanding of this particular structure.

패턴기반기계번역방식은 원시언어패턴과 그에 대한 대역언어패턴들의 쌍을 이용하여 구문분석과 변환을 수행하는 기계번역방식이다. 패턴기반 기계번역방식은 번역할 때 발생하는 애매성을 해소하기 위해 패턴의 길이를 문장단위까지 늘이기 때문에, 패턴의 수가 급증하는 문제점을 가진다. 본 논문에서는 패턴의 단위를 구단위로 한정시킬 때 발생하는 애매성을 해소하는 방법으로 시소러스를 기반으로 한 두단계 대역어 선택 방식을 제안함으로써 효과적으로 애매성을 감소시키면서 패턴의 길이를 줄이는 모델을 제시한다. 두단계 대역어 선택 방식은 원시언어의 한 패턴에 대해 여러 가능한 목적언어의 대역패턴들이 있을 때, 첫 번째 단계에서는 원시언어 내에서의 제약조건에 맞는 몇가지 대역패턴들을 선택하고, 두번째 단계에서는 목적언어 내에서의 제약조건에 가장 적합한 하나의 대역패턴을 선택하는 방식이다. 또한 본 논문에서는 이와 같은 모델에서 패턴의 수가 코퍼스의 증가에 따른 수렴가능성을 논한다.

컴퓨터 성능의 급속한 발전으로 언어 학습에 컴퓨터를 이용하려는 시도는 이제 새로운 언어 교수법 차원으로 발전하는 실정이다. 이에 따라 컴퓨터를 이용한 학습이 더욱 강조되면서, 많은 학습 프로그램이 개발되고 있다. 그러나, 기존 영어 단어 학습 시스템은 학습자에게 지나치게 많은 단어들을 단순한 방법을 통해서 학습하게 함으로써 심리적 부담을 주고 있다. 심리언어학에서는 언어 이해의 과정이 단순히 제시된 것을 그대로 받아들이는 수용의 과정이 아니라 학습자가 이미 보유한 경험과 개념을 근거로 활성망의 확산을 통해 적절한 관계를 찾는 역동적 능동적 과정이라는 이론이 있다. 본 논문에서는 언어 학습 이론을 바탕으로 단어들 사이의 관계를 부각시킴으로써 추론과 기억에 도움을 주는 영어 단어 학습 시스템을 제안한다. 본 시스템은 단어들 간의 관계를 정의한 단어 관계 망을 중심으로 단어 학습 순서를 결정할 수 있고, 이미지 및 게임 기능을 지원하여 단어학습의 흥미를 유발하는 특징이 있다.

본 논문은 공통적으로 이용할 수 있는 웹 환경에서의 한국어 정보로 획득할 수 있는 정보의 양이 영어권 정보의 양보다 상대적으로 적다는 것을 토대로, 웹정보 이용의 불균형을 해소하고자 하는 목적으로부터 출발하였다. 최근에는 지식 정보의 세계화, 국제화에 따라 동일한 정보를 각국 언어로 제공하고자하는 연구가 꾸준히 증가하고 있다. 온라인 백과사전인 위키피디아 역시 현재 다국어로 제공이 되고 있지만 한국어로 작성된 문서는 영어로 작성된 문서의 5% 미만인 것으로 조사되었다. 본 논문에서는 위키피디아 내에서 제공하는 다국어간의 링크 정보와 인포박스 데이터를 활용하여 위키피디아 문서 내에서 개체명을 인식하고, 자동으로 개체명의 영-한 대역어 쌍을 추출하는 것을 목표로 한다. 개체명은 일반 사전에 등재 되지 않은 경우가 많기 때문에, 기계번역에서 사전 데이터 등을 활용하여 개체명을 처리하는 것은 쉽지 않으며 일반적으로 음차표기 방식을 함께 사용하여 해결하고 있다. 본 논문을 통해 위키피디아 데이터를 활용해 만들어진 영-한 개체명 대역어 사전을 구축하기 위해 사용된 기술은 추후 위키피디아 문서를 기계번역하는데 있어 동일한 방법으로 사용이 가능하며, 구축된 사전 데이터는 추후 영-한 자동 음차표기 연구의 사전 데이터로도 활용이 가능하다.

'Emotional value' has been a buzz word for design and ergonomics in the era of business innovation. However, the complication of 'emotion' in terms of literal and practical meaning has made it a challenging but confusing task for designers to develop a new product with emotional value. 'Sensibility' and 'emotion' are interchangeable terms to describe human feeling ('gamsung' in Korean). The confusion reached at its peak with Korean terms. Even scholars in Korean language, psychologists, ergonomists, and designers are bewildered at the choice of proper expression for human feeling in both Korean and English. The difficulty could explain the problems in 'sensibility ergonomics' in Korea. The purpose of this paper is to provide both fundamental and satisfying information with people in the area of 'sensibility ergonomics'. Therefore, in this paper, a number of articles and books on sensibility, psychology, sensibility ergonomics, and design were reviewed to clarify the meaning of sensibility and relationship among similar words that have been used with unintentional misunderstanding. Also many adjectives on human sensibility were collected and complied for the use of sensibility evaluation.

This study examines the duration of Korean lax and tense stops in the prosodic word-medial position, their interactions with nearby segments, and the phonological implications of these interactions. It first examines the lengthening of consonants at the function of the short lax stop. Experiment 1 shows that the sonorant C1 is significantly longer before a short lax stop C2 than before a long tense stop. Experiment 2 shows that the short lax stop C1 cancels the contrast between the lax and tense obstruent at C2, making them appear as long tense obstruents (Post-Stop Tensing Rule). We suggest that such lengthening phenomena occur in Korean to robustly preserve the contrastive length difference between C and CC. Second, this study examines the vowel shortening, known as Closed-Syllable Vowel Shortening, before a long tense stop or before the consonant sequence. Experiment 3 suggests that it be interpreted as temporal adjustment to make the interval from the onset of a vowel to the onset of the following vowel of near-equal length. Conclusively, we suggest that Korean speech be planned and controlled with two specific intervals. One is the duration of contrastive consonant intervals between vowels, and the other is the duration from the onset of a vowel to the onset of the following vowel.
