Abstract

In this study, we investigated the information users' needs and information seeking behavior in the field of science and technology. We found that the science and technology researchers most frequently needed information while conducting the research & development related tasks and drafting research papers. The researchers attributed the main sources of research ideas to be the communication among colleagues and the literature review. The researchers's most preferred information sources were digital libraries, web search engines, and academic information portal. In conclusion, the science and technology researchers regarded the online use of electronic materials as the primary source of information. We hope that this investigation reported herein to be the foundation for developing user-centered information services for the science and technology discipline.

Abstract

In this study, web link analysis of the Korean National Archives has been performed using LexiURL to show the dynamic web flow of the National Archives and to identify which closely related institutions the archives should seek to cooperate with for developing an institutional strategic plan. Inlink and co-inlink analysis were performed and, to identify related institutions of the Korean National Archives, a comparison was made with other countries such as Australia, England and the United States. Through web link analysis, several features can be detected and future directions are suggested. Most inlinks and co-inlink of the Korean National Archives were from public institutions, indicating that relationships with educational or research institutions are weak. Moreover, Korean National Archives involve fewer web links related to international activities than other countries. Proceeding from these results, educational function, research function and international activities should be fortified. Korean National Archives need to provide more materials for supporting educational and research activities and more cultural interchange among related institutions. Further research with different heritage institutions such as libraries or museums is needed.

최근 웹 환경이 대중화되고 개방됨에 따라 웹은 단순한 정보 획득의 공간이 아닌, 의견 표출과 교환의 장이 되어 가고 있으며, 이에 따라 웹 상에서 표출된 특정 주제에 대한 사람들의 의견을 자동으로 검색하기 위한 기술 개발의 필요성이 점차 증대되고 있다. 이러한 의견 문서 검색 문제는 사용자 질의와 문서간의 적합성만을 고려하는 일반적인 정보검색 방법으로는 해결하기 어려우며, 문서 내 의견 포함 여부 분석을 수행할 수 있는 더욱 진보된 시스템을 필요로 한다. 본 논문에서는 기존 검색 시스템의 구조 하에서, 의견 문서 검색을 효과적으로 수행할 수 있는 시스템을 제안한다. 의견 검색을 수행하기 위해 문서 내 의견 분석 방법에 대해 기존의 사전 기반 방식과 기계학습 기반 방식을 결합한 새로운 혼합 방식을 제안하고, 실험을 통하여 검색 성능을 개선하는 효과가 있음을 보였다.

Abstract

Recently, as its growth and popularization, the Web is changed into the place where people express, share and debate their opinions rather than the space of information seeking. Accordingly, the needs for searching opinions expressed in the Web are also increasing. However, it is difficult to meet these needs by using a classical information retrieval system that only concerns the relevance between the user's query and documents. Instead, a more advanced system that captures subjective information through documents is required. The proposed system effectively retrieves opinionated documents by utilizing an existing information retrieval system. This paper proposes a kind of hybrid method which can utilize both a dictionary-based opinion analysis technique and a machine learning based opinion analysis technique. Experimental results show that the proposed method is effective in improving the performance.

Abstract

As resource sharing becomes more active and complicated in academic libraries, a better understanding of how librarians-a key stakeholder-view the current level of resource sharing is needed. Using survey method, this study collected data regarding the perception of 78 librarians with regard to interlibrary loan, document delivery, union catalog construction, shared acquisition, and community building. Overall, the respondents evaluated well-established forms of resource sharing(interlibrary loan, document delivery, and union catalog construction) more positively than less-well developed ones(shared acquisition and community building). Correlation analysis between perception of library/individual characteristics was conducted. Barriers to each of the five areas of resource sharing are also identified in the study.

국가경쟁력의 근간은 대학경쟁력이고 대학경쟁력은 학술·연구·정보경쟁력에서 나온다고 할 수 있다. IMD는 국가경쟁력에서 2위를 한 싱가포르가 대학경쟁력에서 1위를 한 것으로 보고하였으며, 국가경쟁력은 대학경쟁력에서 나온다고 평가한 바 있다. 그러나 우리나라에서는 국가 지식인프라 구축사업이 국가 단위의 종합적 계획없이 진행되고, 지식정보자원의 총량 분석없이 산발적·경쟁적으로 진행된 관계로 일반적인 정보원구축에 중복 투자가 되는 반면에 수집이 어렵고 많이 활용되지는 않으나 역사적·학술적·문화적 가치가 있는 정보원은 오히려 소외되는 현상이 발생했다. 이에 본 연구에서는 국가 자산인 국가지식정보자원 중 학술정보자원만이라도 총체적으로 관리하고 학술자원에 대한 총량분석을 기반으로 한 예산 투자 및 정보화사업과제가 발굴될 수 있도록 하기 위해 학술자원관리시스템 구축을 제안하고자 한다. 즉, 학술자원의 효율적 연계, 보급, 활용을 위해서는 관리체계가 필요하다고 보고, 이를 효과적으로 추진하기 위해 지식기반시대에 적합한 국가단위학술자원관리 체제 구축을 제안하고자 한다.

Abstract

National competence is based on the quality of university education, which is determined by the competitiveness of academia, research and information. IMD reported that Singapore, #2 country in national competence index, topped in quality of university education. Meanwhile Korea's current national knowledge infrastructure project lacks comprehensive coordination at a governmental level and has been conducted in a rather sporadic manner, without any consideration on the overall analysis of knowledge information resources. Consequently, a disproportionate amount of attention was devoted to collecting general information resources, while neglecting rare, hard-to-collect sources with historic, academic, and/or cultural values. This study proposes to build an academic resource management system to fully supervise academic resources at least, among national knowledge information resources which is a national asset, and also to allocate budget and cultivate new information building projects based on overall analysis on academic resources. In other words, there is a need for a management system to implement efficient linkage, distribution and utilization of academic resources and, to that end, we need to build an academic resource management system at a national level, maximizing the benefits from the knowledge society that we live in.

공공도서관 문화프로그램에 대한 중요성이 커짐에 따라 그 경제적 효과에 대하여 전반적으로 평가할 필요성이 제기되어 왔다. 본 연구는 문화프로그램의 경제적 가치를 분석하기 위한 방법으로 기존에 사용되어 온 가상가치평가법의 대안으로 DM 포맷과 IBM 포맷을 제안하였다. 또한 이 모형을 공공도서관이 적용할 수 있도록 사례분석을 통해 그 과정을 구체적으로 설명하고 있다. 이 연구는 가상가치평가법의 바이어스를 최대한 감소함으로써 공공도서관의 정확한 가치를 평가할 수 있는 기본 틀을 마련하였다는 데에 그 의의가 있다.

Abstract

The need for overall assessment of economic effectiveness of library culture program has been suggested, as its importance continues to grow. Our study proposed a new assessment method by applying DM format and IBM format to contingent valuation method that has been used for analyzing the economic value of culture program. This study also illustrates the process through case analysis so that the public library can apply this model. It is meaningful that the study provides basic framework to evaluate the fair value of the public library by minimizing the bias that the contingent valuation method has.

본 연구는 빠르게 발전되는 네트워크 환경을 고려한 분산된 자원 활용에 필요한 기반 연구이다. 앞으로의 자원공유에 대한 노력은 기술적인 문제가 아닌 의미적인 상호운용성이 강조되어야 한다. 이를 위해 본 연구에서는 자원공유를 위한 컬렉션 단위 기술(collection level description; 이하 CLD라고 함) 모형을 제안하였다. 먼저 컬렉션의 범위, 구축목적, 관련 행위자들을 기반으로 하여 컬렉션에 대한 정의를 설명하였으며, CLD의 중요성을 강조한 연구와 그와 관련된 표준들을 비교·분석하였다. 마지막으로는 기존의 CLD의 기능에서 보강되어야 할 관계 중심의 모형 구축을 시도하였으며, 이를 위해 온톨로지 개념을 사용하였다. 온톨로지기반 CLD 모형은 새로운 관계를 창출하기 위한 다양한 표현 기술들을 정의하였다. 기존 연구와는 달리 클래스와 속성을 구별하고, 속성 중에서도 클래스 자체에 대한 특성과 클래스들 간의 관계를 연결하는 속성으로 나누어서 제시하였다.

Abstract

This study is based on the practical use for distributed resources considering growing network rapidly. The focal point of this study will be argued on semantic interoperability for sharing of resources, not be emphasized the technical issues of network. The aim of this article is developing the model of Collection-Level Description(CLD) for sharing of resources. The present article consists of a definition of collection in relation to the scope, objectives, and agents of the collection and an analysis of researches about CLD strengths and standards. Lastly, it was intended to construct the model focused on relation which was needed to be strengthened the existing CLD's function, thus, this study attempted to use the concept of ontology. The model of CLD based on ontology suggested the description could represent new relations inferred between classes and properties. Distinguishing class and property, furthermore, this study suggested properties were separated the characteristic of class and the relation with classes.
