Semantic clustering is important to various fields in the modem information society. In this work we applied the Independent Component Analysis method to the extraction of the features of latent concepts. We used verb and object noun information and formulated a concept as a linear combination of verbs. The proposed method is shown to be suitable for our framework and it performs better than a hierarchical clustering in latent semantic space for finding out invisible information from the data.

As the demand of English education is increasing, the demand for Native English speaking teachers (NEST) is rising, especially in Asian countries. However, due to the low number of NEST, the Korean government is suggesting that Filipino Women be used as English teachers as an alternative. This study aims to answer three questions: (1) are Filipino women in Korea qualified to teach English based on the error analysis of their written essays? (2) what are the linguistic features found in their diagnostic essays? and (3) is their written English better than Korean college students' written English based on the comparison of the two groups? The findings from the Filipino participants show the most frequently occurring errors are related to punctuation usage (commas and hyphens), vocabulary (word choice), verb usage, redundancy, and even as basic as capitalization usage. The results from the comparison of the two groups show that the percentage of the Filipino participants' written error was 14% while the percentage of the Korean participants was 17%. The findings would give us some ideas on the qualification of Filipino women in Korea as English teachers.

Of interest to second language researchers and classroom teachers today is whether and in what wats formal instruction can promote the development of appropriate use of the target language. Most formal instruction is closely related with the use of textbooks in ESL classrooms, so this study focuses on ESL textbooks. In order to learn to communicate successfully, students should use textbooks which specify the rules of language use for the community in which they are operating. This study examines the speech acts of compliment across 8 middle school English textbooks published in Korea. This study analyses the speech acts of compliment according to the following criteria : 1) vocabulary - adjective, verb, intensifier 2) sentence pattern 3) social strategy - invitation to talk, greetings, farewells, expression of gratitude, etc. 4) types of response. As a result of this study some suggestions is giver to promote the development of appropriate use of English through English textbooks.

The purpose of this paper is to make a design and implementation of a diagnosis system of learning misconception of students who learn 'be' verb in the English language by using fuzzy theory. In this system, a fuzzy cognitive map exposes the fact that students' perception and misunderstanding about 'the English' language have an intertwined relationship, and diagnoses causes of misconceptions of students by using fuzzy memory associative memory. It suggests that since most existing systems of rule based expert system have had several limitations, this system will be applied to diagnose learners' misconception of learning in varieties of education areas.

본 논문에서는 말뭉치로부터의 분포 정보를 이용하여, 의미 중의성을 지닌 한국어 동사의 의미를 분별하고자 한다. 분포 정보란 말뭉치내에서 목적어-서술어 관계에 있는 명사와 동사의 분포를 의미한다. 이 분포 정보는 명사 분포와 동사 분포로 나누어 생각할 수 있는데, 본 논문에서는 이 두가지 분포 정보를 사용함으로써 명사 분포만을 이용하였을 때 나타나는 자료 부족 현상을 등사 분포 정보를 이용하여 보완하였다. 분포 정보간의 유사도 계산은 정보 이론에서 사용하는 상대 엔트로피를 이용한다. 품사가 태깅된 50만 단어의 한국어 말뭉치로부터 분포 정보들을 추출하여 한국어 동사 10개에 대해 실험하였다.

본고는 한국어에 나타나는 동사의 연쇄현상(serialization in verbals)에 있어서 단일절(mono-clausal)내에서 소위 복합동사(compound verb)라 불리는 일련의 동사들의 결합 현상을 고찰한다. 연결사(linker/connective)를 매개로 서로 결합하는 동사 연쇄증에는, 일반적으로 동사하나가 하나의 사건을 나타내는데 비해 2개 이상의 동사가 배열됨에도 동시에 일어나 묶여질 수 있는 하나의 사건(single event)을 지칭하는 동사부류가 존재하는데, 이를 통해 동사 결합간 긴밀성을 우선적으로 유추할 수 있고, 역으로 통사적 현상에 의해 그 긴밀성이 확인된다는 점에서 문장 접속의 통어적 구성과는 다른 문법범주 형성을 뒷받침하는 개념적 근거가 된다. 여기에서는, 이러한 연속동사구성(연쇄동사)에 있어 행위성/비대격성을 지니는 동사들간의 연쇄현상을 제약하는 여러 원인들을 검토하고 아울러 이들의 의미적 범주선택을 고려한 거르개로서의 생성여과 규약을 제안한다.

Most of the previous approaches to English agreement phenomena have relied upon only one component of the grammar (e.g., either syntax, or semantics, or pragmatics). This paper argues that interrelationships among different grammatical components play crucial roles in such phenomenon too (cf. Kathol 1999 and Hudson 1999). The paper proposes that, contrary to traditional wisdom, English determiner-noun agreement is morpho-syntactic whereas subject-verb and pronoun-antecedent agreement are reflections of index agreement (cf. Pollard and Sag 1994). The present hybrid analysis of English agreement shows the importance of the interaction of different components of the grammar in accounting for English agreement phenomena. In particular, once we allow morphology to tightly interact with the system of syntax, semantics, or even pragmatics, we could provide a solution to some puzzling English agreement phenomena. This allows a more principled theory of English agreement.

Linguistically, 'Focus' is the element which includes new or unpresupposed information. It is usually signalled by prosodic prominence called the 'pitch accent'. The purpose of this study is to observe the realization of the focal accent in VP-ellipsis, especially, to affect the meaning recovery of elided VP. Asher (1999) gave evidence that focal stress should be on the higher verb and the AUX in order to recover the elided VP to the lower one. In this paper, the systematic patterning of focal accent to decide the elided meaning in VP-ellipsis is to be observed. The realization of focal accent by English native speakers is set as the criteria for the meaning recovery of the elided VP and is compared to Koreans'. Moreover, the focal accents of Koreans are observed and compared with respect to their English proficiency levels.

The purpose of this study was to understand clothing culture in the middle of Chosun Dynasty by observing the vocabularies in Mrs. Sooncheon Kim's letters written in pure Korean in the 16th Centuries. To analyze the vocabulary, classification was made into three groups : names of clothing, material, verb, and observe the constituent and change on vocabularies. The results are as follows : - The vocabularies of clothing in letters in 16th Centuries consist of pure Korean, Chinese and Mongolia, and most of them are pure Korean. - Most of the vocabularies which are not used today were pure Korean : Garamei·Myentei…. - The vocabularies changed and used today had the definite meaning from that of general : Godo, Cheksum. The vocabularies of material haying various unit of measurement and grade according to the material of clothing mean the systematic development of physical culture of that time, and the development of the various modifications of the act and expression mean the varlous ways of clothing life.

Most sentiment analysis systems count the number of occurrences of sentiment expressions in a text, and evaluate the text by summing polarity values of extracted sentiment expressions. However, linguistic contexts of the expressions should be taken into account in order to analyze sentimental orientation of the text meticulously. Korean auxiliary predicates affect meaning of the main verb or adjective in some ways while attached to it in their usage. In this paper, we introduce a new approach that handles Korean auxiliary predicates in the light of sentiment analysis. We classify the auxiliary predicates according to their strength of impact on sentiment polarity values. We also define compositional rules of auxiliary predicates to update polarity values when the predicates appear along with sentiment expressions. This approach is implemented to a sentiment analysis system to extract opinions about a specific individual from review documents which were collected from various web sites. An experimental result shows approximately 72.6% precision and 52.7% recall for correctly detecting sentiment expressions from a text.
