An experiment was conducted to investigate the effect of three types of prior knowledge (domain related knowledge, summary-writing strategy knowledge, and neutral unrelated knowledge) and two types (analytic and wholistic) of cognitive styles on the quality of the summary writing of a descriptive text. The results showed that learning domain-related knowledge and summary-writing-strategy knowledge increased the level of understanding of the target text and the quality of the summary; the former operating mainly at the understanding phase, and the latter operating mainly during the summary planning and producing phases. The effect of the types of cognitive style was found somewhat limited but mainly operating In the process of planing the summary. Other features of time course in writing a summary were further discussed.

Online discussion bulletin in Korea is not only a specific place where user exchange opinions but also a public sphere through which users discuss and form public opinion. Sometimes, there is a heated debate on a topic and any article becomes a political or sociological issue. In this paper, we propose how to analyze the popularity of articles by collecting the information of articles obtained from two well-known discussion forums such as AGORA and SEOPRISE. And we propose a prediction model for the article popularity by applying the characteristics of subject articles. Our experiment shown that the popularity of 87.52% articles have been saturated within a day after the submission in AGORA, but the popularity of 39% articles is growing after 4 days passed in SEOPRISE. And we observed that there is a low correlation between the period of popularity and the hit count. The steady increase of the hit count of an article does not necessarily imply the final hit count of the article at the saturation point is so high. In this paper, we newly propose a new prediction model called 'baseline'. We evaluated the predictability for popular articles using three models (SVM, similar matching and baseline). Through the results of performance evaluation, we observed that SVM model is the best in F-measure and precision, but baseline is the best in running time.

This study analyzed the 6th grade elementary science textbook 'Science stories' reading process of students by utilizing eye movement tracking techniques. Participants read 3 articles in the new experimental science textbooks and solved 9 problems about each article. By understanding and academic achievement results, participants were divided into high-groups, middle-groups, and low-groups. The results of eye movement characteristics of the high-groups and low-groups had the following differences. Number of fixations and number of regressions were higher in high-groups. Average fixation duration and average regressive fixation duration were longer in low-groups. Fixation time for the key sentence of the article was longer in high-groups. Analysis of a scan path and post-interview, high-groups had frequent regression between sentences and they knew where the core of the article is and paid much attention there. In contrast low-groups are sequentially read most articles and some of them had a leap of abnormal range. Problem-solving approach is also different between groups. In conclusion reading style is associated with the science stories comprehension and students who had more regressions, much core search process, effective attention distribution, high concentration showed better understanding results. Also words or sentences used in textbooks are associated with science stories comprehension.

본 연구는 패션앱 후기글에 나타나는 구매자의 의견에 대한 '평가분석(Evaluation Analysis: EA)'을 수행하여, 이를 기반으로 상품의 검색 및 추천을 수행하는 의류 검색추천 챗봇을 개발하는 LICO 프로젝트의 언어데이터 구축의 일환으로 수행되었다. '평가분석 트리플(EAT)'과 '평가기반요청 쿼드러플(EARQ)'의 구성요소들에 대한 주석작업은, 도메인 특화된 단일형 핵심어휘와 다단어(MWE) 핵심패턴들을 FST 방식으로 구조화하는 DECO-LGG 언어자원에 기반하여 반자동 언어데이터 증강(SSP) 방식을 통해 진행되었다. 이 과정을 통해 20여만 건의 후기글 문서(230만 어절)로 구성된 EVAD 평가주석데이터셋이 생성되었다. 여성의류 도메인의 평가분석을 위한 '평가속성(ASPECT)' 성분으로 14가지 유형이 분류되었고, 각 '평가속성'에 연동된 '평가내용(VALUE)' 쌍으로 전체 35가지의 {ASPECT-VALUE} 카테고리가 분류되었다. 본 연구에서 구축된 EVAD 평가주석 데이터의 성능을 평가한 결과, F1-Score 0.91의 성능 평가를 획득하였으며, 이를 통해 향후 다른 도메인으로의 확장된 적용 가능성이 유효함을 확인하였다.

While reading text-only documents and finding unknown words, readers will become the focus disturbed and not be able to understand the content of the documents. Because children have little experience, it is difficult to understand correctly if the description in context is unfamiliar or ambiguous. In this paper, in order to help understand the text and increase the interest of the readers, we analyze the texts of documents and select the contents that are considered important, and implement a system that displays the most relevant images automatically from the web and links the texts and the images together. The implementation of the system divides the article into paragraphs, analyzes the text, selects important sentences for each paragraph and the important words that best represent the meaning of the important sentences, searches for images related to the words on the web, and then links the images to each of the previous paragraphs. Experiments have shown how to select important sentences and how to select important words in the sentences. As a result of the experiment, we could get 60% performance by evaluating the accuracy of the relation between three selected images and corresponding important sentences.

This study investigated global and local characteristics of eye movement while 30 college students read easy and difficult Korean texts. It was found that readers who read the difficult text fixated longer for about 217ms and made shorter saccades of about 3.7 characters while readers who read the easy one fixated for about 190ms and made saccades of about 4.8 characters. Single fixation times and gaze durations in the difficult text were longer than those in the easy one(227ms vs. 195ms; 266ms vs. 210ms). In both easy and difficult texts, the effects of word frequency and eojeol length were found. In addition, the differences in fixation times according to word frequency and length were larger in the difficult text.

분단으로 빚어진 남북한 사회의 이질화는 한글과 조선글이라는 쌍둥이의 탄생으로 연결되고, 이들 둘은 자모순이 다르고 음절 부호화 방식을 채택하였기 때문에 정보교환을 함에 있어서 돌아오지 못할 다리를 건너고 말았다. 이제 남북경협의 본격화가 예상되고 그에 따른 정보교환의 급증이 예상되는 시점에서 최근 개정된 조선글 두바이트 부호 국규 9566-97의 분석을 통하여 양 문자를 통합할 수 있는 기틀을 마련하고자 한다 여기서 문제 해결의 핵심은 자모순이 서로 다름으로 인하여 빚어지는 것으로 이들 남북의 자모순 및 정보교환용 문자부호 표준화를 위하여 몇 가지 모색을 하고 방법을 논한다. 또한 남한안 일변도인 국제 문자부호 표준에 대하여 북한의 수정요구가 진행되고 있고 그 내용과 조선글 두바이트 부호안을 종합하여 표준을 마련하기 위한 기본 방향을 설정하고 허배선생의 연구를 통하여 새로운 자모순 모색의 가능성을 논한다.

The purpose of this study is to analyze the science reasoning differences of elementary school students' science writing. For this purpose, science writing activities and analysis frameworks were developed. Science writing data were collected and analyzed. Third to sixth grade elementary students were selected from a middle high level elementary school in terms of a national achievement test in Seoul. A total of 320 writing materials were analyzed. The results of the analysis were as follows. Science writings show science reasoning at 52 % for $3^{rd}$ grade, 68% for $4^{th}$ grade, 85% for $5^{th}$ grade, and 89% for $6^{th}$ grade. Three types of scientific reasoning such as inductive reasoning, deductive reasoning, and abductive reasoning appeared in science writing of the third to sixth graders. The abductive reasoning appeared very low in comparing with inductive and deductive reasoning. Level three appeared the most frequently in the science writing of the elementary students. The levels of inductive and deductive reasoning in science writing increased according to increasing grade and showed statistical differences between grades. But the levels of abductive reasoning did not show an increasing aspect according to increasing grade and also did not show statistical differences between grades. The levels of inductive reasoning and deductive reasoning of the 3rd grade was very low in comparing with the other grades.
