전통적으로 학위논문은 우수한 학술정보적 가치를 내포하고 있음에도 불구하고 물리적 이용가능성의 부재로 인하여 평가 절하되어 왔다. 이를 해소하려면 전자형 학위논문시스템의 개발이 필요하며, 그것은 정보탐색 과정에서 연구결과를 배포하는 기본채널로 그리고 학위논문이 핵심자료임을 인식시키는 계기를 제공할 것이다. 그래서 최근에 각국의 많은 대학(도서관)이 디지털 환경에 부응할 목적으로 전통적(인쇄형) 학위논문을 전자버전으로 변환하고 있다. 이에 주목하여 본 연구는 웹설문지와 홈페이지 조사방식으로 학위논문 관리시스템의 현황을 분석한 선행연구를 이론적 배경으로 삼아 국내 학위논문의 표준관리모형을 제안하였다.

Abstract

Traditionally, theses and dissertations have been extremely underutilized information sources due to their lack of physical availability. The development of electronic theses and dissertations system will provide the opportunity for theses and dissertations to be recognized as a basic channel for the dissemination of research findings and an essential resource in the discovery process. In digital environment, many universities and libraries throughout the world are now making digitized versions of traditional(print) dissertations available online. The purpose of this paper is to analyze the current theses and dissertations management system based on web questionaries and survey of home pages, and to suggest a standardized theses and dissertation management model in Korea.

The purpose of this study is to present a theoretical framework and practical methodology to extend the scope of Library and Information Science by incorporating the usability evaluation of e-book, which has considerably increased in proportion in the digital library. By surveying e-book users and through statistical analysis, it was found that rebuilding a set of usability evaluation factors for e-books is necessary to activate e-books in the digital libraries. This study inclusively presents a conceptual model of e-book usability evaluation and suggests guidelines for usability principles. 攀＊＊＊ 본 연구는 연세대학교 대학원 박사학위논문의 일부를 요약한 것임.＊＊＊ 서울경제신문 편집부 문화레저부 기자(india2121@empal.com)＊＊＊＊연세대학교 문과대학 문헌정보학과 교수(swhan@yonsei.ac.kr) 논문접수일자 : 2004년 8월 19일 게재확정일자 : 2004년 9월 10일攀攀

This experimental study proposes a multi-document summarization method that produces optimal summaries in which users can find answers to their queries. In order to identify the most effective method for this purpose, the performance of the three summarization methods were compared. The investigated methods are sentence clustering, passage extraction through spreading activation, and clustering-passage extraction hybrid methods. The effectiveness of each summarizing method was evaluated by two criteria used to measure the accuracy and the redundancy of a summary. The passage extraction method using the sequential bnb search algorithm proved to be most effective in summarizing multiple documents with regard to summarization precision. This study proposes the passage extraction method as the optimal multi-document summarization method. 攀＊＊＊ 본 연구는 연세대학교 대학원 박사학위논문의 일부를 요약한 것임.＊＊＊ 연세대학교 문헌정보학과 시간강사(shchoi@lis.yonsei.ac.kr)＊＊＊＊연세대학교 문헌정보학과 교수(ymchung@yonsei.ac.kr) 논문접수일자 : 2004년 8월 27일 게재확정일자 : 2004년 9월 13일攀攀

Abstract

초록

The purpose of this study is to generate the local level knowledge structure of a single document, similar to end-of-the-book indexes and table of contents of printed material, through the use of term clustering and cluster representative term selection. Furthermore, it aims to analyze the functionalities of the knowledge structure, and to confirm the applicability of these methods in user-friendly information services. The results of the term clustering experiment showed that the performance of the Ward's method was superior to that of the fuzzy K-means clustering method. In the cluster representative term selection experiment, using the highest passage frequency term as the representative yielded the best performance. Finally, the result of user task-based functionality tests illustrate that the automatically generated knowledge structure in this study functions similarly to the local level knowledge structure presented in printed material.攀＊＊＊ 본 연구는 연세대학교 대학원 박사학위논문의 일부를 요약한 것임.＊＊＊ 日本 慶應義塾大學(Keio University) 圖書館情報學科 訪問硏究員(libinfo@yonsei.ac.kr)＊＊＊＊연세대학교 문헌정보학과 교수(ymchung@yonsei.ac.kr) 논문접수일자 : 2004년 8월 17일 게재확정일자 : 2004년 9월 10일攀攀
