It is useful to find something valuable for researching through literature based discovery. Swanson's ABC model, known as literature based discovery, suggests the relationship between entities undiscovered yet. This study tries to find the valid relationship between entities by referring to citation which connects articles on similar topic. We collect citation from references in articles, and extract important concepts in titles and abstracts through text mining techniques. We reproduce the relationship between fish oil and Raynaud's disease, which is known as one of Swanson's works, and compare the results with entities identified from traditional approach.

Due to the recent development of Information and Communication Technologies (ICT), the amount of research publications has increased exponentially. In response to this rapid growth, the demand of automated text processing methods has risen to deal with massive amount of text data. Biomedical text mining discovering hidden biological meanings and treatments from biomedical literatures becomes a pivotal methodology and it helps medical disciplines reduce the time and cost. Many researchers have conducted literature-based discovery studies to generate new hypotheses. However, existing approaches either require intensive manual process of during the procedures or a semi-automatic procedure to find and select biomedical entities. In addition, they had limitations of showing one dimension that is, the cause-and-effect relationship between two concepts. Thus;this study proposed a novel approach to discover various relationships among source and target concepts and their intermediate concepts by expanding intermediate concepts to multi-levels. This study provided distinct perspectives for literature-based discovery by not only discovering the meaningful relationship among concepts in biomedical literature through graph-based path interference but also being able to generate feasible new hypotheses.

This study investigated how Problem-Based Learning method effects on students' Self-Regulated Learning Strategies especially for the LIS education. For this purpose, the differences in students' self-regulated learning strategies were examined as a pre and a post survey using the same questionnaire. Correlation between cognitive and motivational self-regulated learning strategies was examined, and the details of the SRL's sub-components were measured to see the effects of Problem-based learning. Statistical significance using the paired sample t-test were also conducted. The results revealed that Problem-based learning is effective in improving students' cognitive motivational self-regulated learning and found out the possibilities for a follow-up study for motivational self-regulated learning.

Uncertainty means incomplete stages of knowledge of propositions due to the lack of consensus of information and existing knowledge. As the amount of academic literature increases exponentially over time, new knowledge is discovered as research develops. Although the flow of time may be an important factor to identify patterns of uncertainty in scientific knowledge, existing studies have only identified the nature of uncertainty based on the frequency in a particular discipline, and they did not take into consideration of the flow of time. Therefore, in this study, we identify and analyze the uncertainty words that indicate uncertainty in the scientific literature and investigate the stream of knowledge. We examine the pattern of biomedical knowledge such as representative entity pairs, predicate types, and entities over time. We also perform the significance testing using linear regression analysis. Seven pairs out of 17 entity pairs show the significant decrease pattern statistically and all 10 representative predicates decrease significantly over time. We analyze the relative importance of representative entities by year and identify entities that display a significant rising and falling pattern.

The purpose of this study was to investigate whether students' creative problem-solving skills improve through project-based courses. Rather than measuring overall competencies, the focus was specifically on measuring the improvement of problem-solving skills. The study involved a literature review, the design of project-based courses, and the assessment and analysis of students' competencies before and after the courses. The results of the study are as follows: Firstly, the measurement of students' creative problem-solving skills before and after the project-based courses indicated an overall improvement in the five dimensions of problem identification, analytical thinking, flexible thinking, alternative generation, and a proactive attitude. Secondly, significant correlations were found among these five dimensions, particularly strong correlations were observed between problem identification and alternative generation, problem identification and analytical thinking, and analytical thinking and alternative generation. To generalize the findings of this study, further research is needed to apply similar approaches in different types of courses and across various universities and departments.

논문에서는 최근 인터넷 상에서 표준 공통 포맷으로 대두되는 XML을 이용하여 웹 기반의 역사자료의 데이터베이스 검색 시스템을 설계 및 구현하였다. 원격 교육 시스템의 참조문헌 지원 시스템을 설계하였다. 컴퓨터 상에서 고문헌 자료 주로 한자를 입력하고 검색할 수 있는 환경이 점차 나아지고 있다고는 하지만, 여전히 원전사료의 한자를 일반적인 환경에서 자유롭게 구현하는 일은 결코 용이하지 않다. 종래의 연구자들은 텍스트 별로 수작업으로 작성한 색인류를 이용하여 연구를 해왔다. 그러나 이러한 색인 이용방법에는 문제가 있다. 색인어로 삼고자 하는 단어를 텍스트에서 추출하는 과정에서 누락되는 경우가 있기 때문이다. 전산화된 데이터는 이른바 '발견적 이용'이라는 관점에서 활용될 수 있다.

This study presents book curation services as one of the ways to establish the social role and status of public libraries in a changing social environment. It aims to identify the quality factors that influence user satisfaction and the intention to continue using public library book curation services. For this purpose, the quality factors were limited to information quality through a literature review on curation services in libraries and various fields, from which specific factors were extracted. A questionnaire survey and statistical analysis were then conducted among public library users. The results showed that among the information quality factors, variety and interestingness affect user satisfaction, while discoverability and usefulness impact both user satisfaction and the intention to continue using the services. Based on these findings, we suggest that public libraries should offer book curation services that allow users to discover new information and select themes that are engaging and interesting, and provide information about various genres and types of books.

Identifying citing sentences from article full-text is a prerequisite for creating a variety of future academic information services such as citation-based automatic summarization, automatic generation of review articles, sentiment analysis of citing statements, information retrieval based on citation contexts, etc. However, finding citing sentences is not easy due to the existence of implicit citing sentences which do not have explicit citation markers. While several methods have been proposed to attack this problem for English, it is difficult to find such automatic methods for Korean academic literature. This article presents a rule-based approach to identifying Korean citing sentences. Experiments show that the proposed method could find 30% of implicit citing sentences in our test data in nearly 70% precision.

The development of Semantic Web basically requires knowledge induced from the formalization and semantization of information, and thus ontology should be introduced as a knowledgization tool. URI(Universal Resource Identifier) is an indispensible scheme to uniquely indicate individuals on ontology. However, it is difficult to find the use cases of URI in real data including science and technology papers. This paper describes the method to construct internal and external human resource information based on URI from the papers. We use co-authors, e-mails, publication date, and affiliation for discriminating authors with the same strings. HRST(Human Resources devoted to Science and Technology) is referred to acquire URIs for human resource. We expect the internal and external human resource information would be adopted to outcome analysis applications such as researcher network analysis and outcome statistics.
