  • As information technology advances and changes in the library environment, a flexible view and reinventing perspective of LIS research is necessary. This study focused on the investigation of the recent(2000-2003) research trends by analyzing the contents of articles from the major academic research journals for getting a future oriented view of the field. A taxonomy developed by Hawkins(2003) was applied in order to find out the major pattern of research in the domestic as well as international LIS Journals, and Chi-Square Tests Analysis was used to figure out if the research pattern has any effect on research environment(vice versa).

  • 본 논문에서는 기존의 키워드 검색 시스템의 불편함과 비효율성을 지적하고 이를 극복하기 위해 한국어 의문문 자체를 질의어로 채택하여 정보를 검색하는 자연어 기반의 정보검색 시스템을 제안하였다. 본 시스템은 주격 주제어와 서술격 주제어는 물론 의문의 초점과 초점 관련 어구에 대해서도 질의어 분석단계에서 분석하여 검색자의 요구에 부응하는 응답문 검색이 가능하도록 설계하였다. 본 논문에서는 의문문 질의 시스템에 적합하도록 의문사를 5형태로 분류하고 실제 한국어 문장에서 이들 각각에 대한 처리를 규칙화시켜 질의어의 체계적인 분석을 시도하였다. 한편, 후보 문장 검색을 위한 색인어로 사용되는 주격 주제어와 서술격 주제어를 정해진 규칙을 통해 추출함으로써 체계적이고 정확도 높은 질의어 분석이 이루어지도록 했다. 뿐만 아니라 의문의 초점과 초점 관련 어구또한 정해진 규칙을 통해 분석 추출함으로써 응답문 검색의 정확성을 높였다.

  • The purpose of this study is to analyze the structure and contents of the articles in the Journal of Korean Home Economics Education Association to review the research trends during the last decade since 2009. In total, 354 articles from 10 volumes, 40 journal books, were analyzed. This amount to 42.3% of total articles in the JKHEEA for the past 30 years. The results showed that the number of articles in the journal continuously decreased by approximately 5 articles each year. More than half of articles were co-authored as a joint-research between professors and teachers or graduate students. The numbers of pages, tables, figures, and references vary greatly among of the articles published in the JKHEEA. The reviewers and authors would need to check if the pages, tables/figures, or references are indispensable, especially in case there are extremely large number of them. Even though survey research with students as participants is still the most common types of research among recent articles, its percentage is decreasing and diverse research methods such as the analysis of textbook or curriculum literature are being used. Also, research integrating the pedagogy and educational content, and in turn developing and evaluating educational programs is increasing, which indicates that the journal identity has become better-defined. It is advisable that authors select the key words that are more relevant to the title, purpose, and research questions. It is expected that the journal revises the publication regulations so that the issues discussed in this study may be reflected.

  • "The Plan for the Development of the National Geographic Information System" designates the following six major thematic maps as the main subject of digital mapping project: topographic-cadastral maps; administrative boundary maps; land use maps; road network maps; national land zoning maps; and urban planning maps. Carrying out the digital mapping project requires standards and guidelines for digitizing process. However, there is neither standards nor guidelines with regard to thematic map production. This study describes the steps involved in producing thematic maps and provides the best procedural alternative for the production of thematic maps. Based on procedural alternative suggested by this study, actual digital maps have been experimentally produced for the selected area, Anyang-Si Dongan-Gu. The results of this experimental work have been utilized to government for not only making the guidelines but also initiating plans for the development of thematic map production.roduction.

  • There have been enormous technological advances in science & technology domain and frequent convergences between its sub-domains. Topic analysis with science & technology corpus is a key process to grasp topic trends and relations between topics. The main objective of this research is to show various analytic approaches with topics extracted from CiteSeer corpus, which is widely used in information technology domain. This paper will also show a case study of Onto-Frame, an R&D support system developed by KISTI, to reveal the role of topics on the system.

Analysis for the Tendency to Study Children's Services in the Field of Library and Information Science: Focused on Masters and Doctoral theses Submitted from 1981 to 2010 (문헌정보학 분야의 어린이 서비스 관련 연구경향 분석 - 1981년~2010년 석.박사 학위논문을 중심으로 -)

  • The purpose of this study is to compare the tendency to study children's services in libraries korea and in North America in order to analyze the implications for future studies in the field of Library and Information Science. Looking at masters and doctoral theses submitted from 1981 to 2010, we analyzed 110 theses in Korea and 89 theses in North America. After reviewing the abstracts of the theses, we classified their subjects into six categories, including the materials, services, programs, administration and management, type of children, and the theory and history behind each library's services. Four things stood out from the study. First, the number of theses in Korea has had a sharp increase recently, but in North America there has been a steady increase for a longer period of time. Second, the theses about library programs are approximately 50% in Korea, but in North America 50% of those theses were about materials for children. Third, in Korea about 90% of the theses are for master's degree, while approximately 90% in North America are for doctoral degree. Fourth, looking at each of the different categories, Korea seemed to focus on the services and programs offered and the administration and management, while North America focused on the materials offered, the type of children to partake in the services and the theory and history behind the services offered.

  • The purpose of this study is to see the intellectual structure in the field of veterinary sciences in Korea, using author profiling analysis(APA), a bibliometric approach. Three journals are selected on the basis of citation data, exchanging most citations with Korean Journal of Veterinary. And then, 50 authors who published most articles at selected journals during the given period of time were chosen. The analysis of similarity and dissimilarity among authors by comparing co-word appearance patterns from article title, abstracts, and keywords was made. Authors can be grouped 11 minor clusters under 4 major clusters, depending on their interests in the area of veterinary sciences in Korea. The subjects for each cluster at the veterinary sciences are decided by the matching the keyword, representing author's research interest. As a result, it is possible to figure out the current research trends and the researcher network in the field of veterinary sciences.

  • Most of the information prevailing in the Internet space consists of textual information. So one of the main topics regarding the huge document analyses that are required in the "big data" era is the development of an automated understanding system for textual data; accordingly, the automation of the keyword extraction for text summarization and abstraction is a typical research problem. But the simple listing of a few keywords is insufficient to reveal the complex semantic structures of the general texts. In this paper, a text-visualization method that constructs a graph by computing the related degrees from the selected keywords of the target text is developed; therefore, two construction models that provide the edge relation are proposed for the computing of the relation degree among keywords, as follows: influence-interval model and word- distance model. The finally visualized graph from the keyword-derived edge relation is more flexible and useful for the display of the meaning structure of the target text; furthermore, this abstract graph enables a fast and easy understanding of the target text. The authors' experiment showed that the proposed abstract-graph model is superior to the keyword list for the attainment of a semantic and comparitive understanding of text.
