기존의 웹 이미지 검색 엔진은 웹 이미지를 검색할 때 웹 이미지의 특징과, 웹 이미지를 포함한 HTML 문서의 텍스트를 이용한다. 그러나, 텍스트는 문맥에 따라 의미가 달라질 수 있으므로, 검색 대상을 미리 분류하면 검색 효율을 높일 수 있다. 본 논문은 웹 문서의 텍스트에서 이미지와 관련이 있는 이미지 설명 텍스트를 자동으로 추출하고, 검색 효율을 높이기 위하여 웹 이미지를 자동으로 분류하는 지능적 웹 이미지 검색 엔진을 제안한다. 지능적 웹 이미지 검색 엔진은 분류와 용어, 용어와 용어 사이의 연관도를 이용하여 분류의 정확도를 높인다.

Given the context of rapid developing ubiquitous computing environment, it is imperative for users to search and use images based on affective meanings. However, it has been difficult to index affective meanings of image since emotions of image are substantially subjective and highly abstract. In addition, utilizing low level features of image for indexing affective meanings of image has been limited for high level concepts of image. To facilitate the access points of affective meanings of image, this study aims to utilize user-provided responses of images. For a data set, emotional words are collected and cleaned from twenty participants with a set of fifteen images, three images for each of basic emotions, love, sad, fear, anger, and happy. A total of 399 unique emotion words are revealed and 1,093 times appeared in this data set. Through co-word analysis and network analysis of emotional words from users' responses, this study demonstrates expanded word sets for five basic emotions. The expanded word sets are characterized with adjective expression and action/behavior expression.

기존의 이미지 검색에서는 원하는 이미지를 검색하기 위하여 사용자가 이미지의 가시적 속성을 정확히 표현하도록 요구함으로써 질의가 제한되었다. 본 논문에서는 색상으로부터 유추될 수 있는 감성 형용사를 감성 용어 시소러스로 구축하여 감성 기반의 이미지 검색이 가능하도록 하였다. 감성 용어 시소러스를 이용함으로써 ‘부드러운’, ‘세련된’등과 같은 감성 용어를 검색의 질의어로 사용할 수 있게 되어 사용자의 검색 의도를 보다 정확하게 표현할 수 있게 되고, 검색의 결과에 대한 만족도를 향상 시킬 수 있다.

본 논문에서는 이미지 검색을 위한 새로운 검색 기법을 제시한다. 기존의 특징기반 검색 기법이나 주석기반 검색 기법은 특징이나 주석에 대하여 색인 형태나 질의 형태가 동일하였다. 그러나, 제안하는 검색 기법은 위의 두 전형적인 검색기법을 혼합한 것으로, 텍스트로 질의하면 질의 텍스트를 질의처리를 통해 텍스트에 포함된 특징용어를 추출하고 특징용어를 이미지가 본질적으로 가지는 특징(color, shape, texture)으로 변환한 다음 그 특징을 질의로 이용하여 특징기반 검색을 하는 기법이다. 이러한 기법은 현재 사용자에게 친숙한 텍스트 질의를 유지할 수 있게 해 주며 앞으로 음성인식을 통한 음성 질의인터페이스가 적용될 경우 더욱 효과적으로 사용될 수 있을 것이다.

The purpose of this study is to identify the characteristics and types of errors in the conceptual image of Korean language learners according to the types of terms in mathematics that are the basis for solving mathematical word problems, and to prepare basic data for effective teaching and learning methods in solving the word problems of Korean language learners. To do this, a case study was conducted targeting four Korean language learners to analyze the specific conceptual images of terms registered in curriculum and terms that were not registered in curriculum but used in textbooks. As a result of this study, first, it is necessary to guide Korean language learners by using sufficient visualization material so that they can form appropriate conceptual definitions for terms in school mathematics. Second, it is necessary to understand the specific relationship between the language used in the home of Korean language learners and the conceptual image of terms in school mathematics. Third, it is necessary to pay attention to the passive term, which has difficulty in understanding the meaning rather than the active term. Fourth, even for Korean language learners who do not have difficulties in daily communication, it is necessary to instruct them on everyday language that are not registered in the curriculum but used in math textbooks. Fifth, terms in school mathematics should be taught in consideration of the types of errors that reflect the linguistic characteristics of Korean language learners shown in the explanation of terms. This recognition is expected to be helpful in teaching word problem solving for Korean language learners with different linguistic backgrounds.

In this paper, some terms of high school mathematics which read Chinese characters phonetically in Hangul are studied semantically. Nowadays, most terms of high school mathematics are terms of Chinese characters given the reading of them in Hangul alphabet. In such terms of Chinese characters, there are many loan-words from daily life and newly coined terms. Some such terms are examined in respect of meaningfulness and rule-ness. The degree of meaningfulness and rule-ness of loan-words from daily life are relative. Students seems familiar to loan-words usually, but it is difficult to know whether students seems to be familiar to loan-words or not. Degree of familiarity to a certain loan-word must be relative. In loan-words, there are such terms whose mathematical meaning is different from daily life meaning. Such terms are strong in rule-ness. Newly coined terms are strong in rule-ness. Students are not familiar to newly coined terms which are not used in daily life and have only mathematical meaning. In coining new terms using Chinese character, unit characters are related directly or indirectly to concept which unit characters want to express. So, It is possible to guess something unit characters want to express by investigating them. According to Vinner(1991), images can be evoked. But in case of reading Chinese characters phonetically in Hangul, it can not be guaranteed for Hangul mathematical terms to evoke images which the original mathematical terms evoked. To solve such problems semantic investigation of mathematical terms has been suggested. Through this process, transplanting images which the original mathematical terms evoked into Hangul terms are planned.

지금까지 자연언어처리에서의 품사태깅(parts-of-speech tagging) 기술에 대한 연구는 활발히 진행된 반면, 전문용어에 대한 처리 기술은 미비한 점이 많았다. 전문용어에 관련된 연구는 대부분 구축, 표준화, 추출 등에 대한 연구가 많았으나 전문용어 태그 설정과 태깅 기술 연구는 부족한 상황이다. 본 논문에서는 전문용어 태그를 (분야정보: 아이디) 순으로 설정하고 백과사전의 분류 체계를 이용하여 어떤 특정 분야 문서의 전문용어를 자동으로 태깅하는 시스템을 구축하였다. 전문용어 태깅 시스템은 형태소분석기를 사용하지 알고 문맥의 규칙과 조사 어미사전을 이용해 자동으로 태깅을 하게 된다. 이 시스템의 정확률 측정을 위한 정답말뭉치는 웹 상에 공개되어 있는 백과사전 html문서를 이용하였다. 우선 백과사전에 나와있는 용어는 전문용어라고 가정한다. 하나의 문서에는 '용어', '요약', '본문', '이미지', '분류', '참조항목' 등의 정보들이 있다. 이 중 '본문'에는 그 용어에 대한 자세한 설명이 있는데 특정 단어에는 태그로 백과사전 내에 있는 단어를 찾아 볼 수 있게 링크 되어있다. 이 정보를 이용해 태그로 되어있는 것을 설정한 태그로 바꾸고 단계별로 확장 태깅을 해서 정답말뭉치를 만든다. 태깅 시스템과 정답말뭉치를 비교해 정확률을 계산해서 시스템의 성능을 측정하였다.

This study was intended to identify the differences in perception of image words and perception dimension of desired image according to sex variable for college students in a school context. Data were collected by questionnaires distributed to 443 college students from August to September of 2000. After eliminating incomplete questionnaires, 396 were analyzed. As results of factor analysis, 7 desired image factors were determined for male and female, respectively. On the basis of these results, major perception differences were identified according to sex variable. Differently-perceived image words were as fellows: For intellectual image, male relates it with sporty while female relates it with graceful; for masculine image, male relates it with mature while female relates it with sporty; and for feminine image, male relates it with sexy and graceful while female relates it modest, pure, and cute. Multidimensional scaling was employed to determine the perception dimension of desired image. Two dimensions were accepted to interpret the results for both sex, respectively. 'Feminine-masculine' and 'conspicuous-plain' were criteria for male students, while 'unnatural-natural' and 'feminine-masculine' were criteria for female students.

This paper focuses on 'clean(cheong: 淸)' kinds of style terminologies among various style terminologies appearing in Heo Gyun's Seongsushihwa("惺?詩話") and tries to analyze the distinctive points which 'clean(cheong: 淸)' kinds of style terminologies include. In Heo Gyun's Seongsushihwa, 11 of 'clean' kinds of style terminologies, such as "cheonggyeong(淸勁), cheonghryang(淸亮), cheongryeo(淸麗), cheongseom(淸贍), cheongso(淸?), cheongweol(淸越), cheongjang(淸壯), cheongjeol(淸絶), cheongjeol(淸切), cheongchang(淸?), cheongcho(淸楚)," were used. This paper focuses and analyzes 'cheonggyeong(淸勁)', 'cheongjeol(淸切)', 'cheongcho(淸楚)', and 'cheongweol(淸越)' that he suggested through applying to real literary pieces. The result of analysis indicates that 'clean' kinds of style terminologies 'cheonggyeong', 'cheongjeol', 'cheongcho', and 'cheongweol' share the same 1st character 'clean(淸)', yet have distinctive qualities by the 2nd characters. These 4 style terminologies all share 'cheong(淸)' image which means clear and clean, yet each one has the attribute of the 2nd character that indicates each one's individual characteristic. It is apparent that 'Cheonggyeong(淸勁)' reflects the 'gyeong(勁)' image meaning upright and solid and implies poems of poets' steadfast spirit within clear boundary; 'cheongjeol(淸切)' reflects the 'jeol(切)' image meaning either desperation and imminence or pitifulness and sorrow and implies poems of poets' urgent and pitiful emotions within clear and clean boundary; 'cheongcho(淸楚)' reflects the 'cho(楚)' image meaning either delicacy and fineness or slenderness and tenderness and implies poems of poets' beautiful but not luxurious, delicate and tender emotions within clear and clean boundary; and 'cheongweol(淸越)' reflects the image of 'weol(越)' meaning unworldliness and excellency and implies poems, within clear and clean boundary, of excellent appearance and mentality surpassing mundane world. Compared with the 1st character's attributes of the style terminologies which Heo Gyun used, the 2nd characters's attributes do not appear that vivid. Especially, in the case that the 2nd characters have similar meanings, it is not easy to clarify the categories. Indeed, in order to grasp clear and distinctive qualities of style terminologies, the kinds of them need to be initially categorized by the 1st characters, and then sorted by the 2nd characters. In this case, the contents which the 2nd characters of style terminologies indicate should be considered. It is because style terminologies explain both literary pieces' aesthetic qualities and writers' personalities, and because explanations about literary pieces' aesthetic qualities includes not only the conclusive poetic or semantic boundaries which literary pieces' created but also literary pieces' creation processes and expression techniques. Through the style terminologies with Heo Gyun used in Seongsushihwa, it can be aware that he evaluated poems focussing more on the conclusive semantic boundaries that poets' spirits and poems created than expression techniques or creation methods. The overall aspects Heo Gyun's such style criticism has will be checked out in more detail through further studies by examining more materials.

Concept images play an important role in the acquisition of mathematical concept. However, sometimes concept images are derivatives of student's misconceptions. In addition, students always learn concept images despite teachers' efforts to teach concept definitions. Therefore, teachers need to know about all the concept images of a particular concept. This study aimed to analyze the concept image that students have about the triangle when they have already learned about the triangle in school. It was found that some students have different concept images about the triangle between Semo. Moreover, many students have misconceptions about vertices, sides, and angles. In particular, students think Gak denotes a side, although it means angle. Based on these results, I suggest that the curriculum and textbook require improvement.
