Although MARC can define the detail cataloguing data, it has complex structures and frameworks to represent bibliographic information. On account of these idiosyncratic features of MARC, XML DTD or RDF/S that supports simple hierarchy of conceptual vocabularies cannot capture MARC formalism effectively. This study implements bibliographic ontology by means of abstracting conceptual relationships between bibliographic vocabularies of MARC. The bibliographic ontology is formalized with OWL that can represent the logical relations between conceptual elements and specify cardinality and property value restrictions. The bibliographic ontology in this study will provide metadata for cataloguing data and resolve compatibility problems between cataloguing systems. And it can also contribute the development of next generation bibliographic information system using semantic Web services.

본 논문에서는 차세대 서지 기술 방법인 BIBFRAME의 적용성을 향상하기 위한 사전 연구로, 공공도서관의 서지 데이터 필드를 분석하여 사용빈도가 높은 주요 필드를 선정하고 각 필드별 태그의 의미를 제시한다. 주요 필드 선정은 실제 사용 중인 최신 서지 데이터를 대상으로 분석을 진행하며, 이를 통해 공공도서관의 다양한 KORMARC 서지 데이터 필드 중 BIBFRAME 변환을 위한 주요 데이터 필드를 추출한다.

Discovery is an emerging concept to enhance the search capabilities of library resources with the Next Generation Library Catalog. This paper defined the Discovery feature based on the information search behavior, and then derived the elements that make up its function. After that, the 11 regional representatives libraries' OPACs and 3 Internet bookstores are evaluated and compared against Search & Discovery capabilities. As a result, the Internet bookstores were superior to the libraries' OPACs for all the elements that make up the Discovery functions. This study verified that the public libraries OPACs are still concentrating on known item search, and it is hard for the users to meet a serendipity which is gained through the Discovery functions.

The purpose of this study is to improve the faceted navigation function of next-generation library catalogs(NGC) using the tables in a classification scheme. Because the tables provide forms or contents of materials systematically, faceted navigation based on the tables can be as effective as faceted navigation based on language, publishing date, or class-level subject facet. Therefore, class numbers based on the Korean Decimal Classification (KDC) were examined and the characteristics of schedules and tables were analyzed. As a result, suggestions to improve faceted navigation was provided. Moreover, the method using the tables does not need additional resources to derive facets because the facet analysis process is always carried out in the classification process.

IPTV와 같은 다양한 멀티미디어 콘텐츠를 다루는 멀티미디어 단말기의 경우에 다량의 콘텐츠 목록으로부터 원하는 내용을 쉽게 선택할 수 있는 편리한 인터페이스가 요구된다. 본 논문에서는 본격 상용서비스가 시작된 IPTV 및 멀티미디어 단말기의 사용자 인터페이스의 현황을 분석하고, 인터페이스의 진화 방향에 대한 특성을 제시한다. 이를 위하여, 국내외 셋탑박스 기반 IPTV 및 멀티미디어 단말기의 인터페이스 사례를 수집하여, 화면의 특성에 따라 화면의 구성 형태 및 인터랙션의 형태를 서비스 시나리오에 근거하여 분류하였다. 셋탑 박스 기반의 IPTV 인터페이스는 I터치인터랙션의 기능을 지원할 수 있는 차세대 TV 리모콘의 개발과 보급이 전제가 된다면, 기존의 멀티미디어 단말기가 수용하고 있는 다양한 그래픽적 터치기반의 인터페이스 형태를 접목하여 차세대 TV 인터페이스로 발전할 수 있을 것으로 전망된다.

The purpose of this study is to examine the possibility of using the WorldCat, an International Union Catalog operated by OCLC as a tool for analyzing the trend of knowledge distribution in libraries around the world. In this study, four subject keywords, that is, Korea, Korean, Japan, and Japanese, were used to search materials related to Korea and Japan, and four facets, including medium, genre, language, and user level, were used to categorize search results from the WorldCat. The result shows that information resources related to Korea held by libraries around the world are only a little more than a third of Japan-related information resources. Especially Korea-related information resources for juveniles are less in numbers and lack in diversity in languages, media and genres, when compared with Japan-related information resources. Also an examination of two bibliographic records demonstrates that viewpoints expressed in user contributed reviews might affect diffusion of knowledge on certain subjects in the Next Generation Library Catalog.

The purpose of this study is to compare and analyze the functions and characteristics of search interfaces of Korean Old and Rare Collection Information System(KORCIS) and Korean History Online. The checklist of OPAC functionalities proposed by Breeding was used to examine eleven functions of these systems. Both system provide the following functions: Search by keywords; Boolean operators in queries; Order results chronologically; Modify search without re-keying the initial terms ; Search within result sets ; and Ability to limit results to an individual library or education. They do not provide such functions as Browse by author, title, subject and View and recall the search history for the current session. Adoption of standard OPAC and next-generation catalog functionalities, in-depth understanding of user needs and information seeking behaviors, and the improvement of subject access to these systems are suggested in this study.

The purpose of this study is to provide an actual basic data and helps for arranging the next generation OPAC's interface and function through improving the existing OPAC's interface and improvement in the domestic library. In this study, factors to be importantly considered for improving the OPAC's interface and function were examined based on the preceding studies on OPAC concept & development process, user's library use style, user use style of OPAC, and recognition on library's crisis, and actual condition investigation result. Also, the case analysis on the existing OPAC's interface and function was focused on the search window, search item, search method, alignment function, search result display and search result feedback. Also, the search interface and search function of the next generation OPAC which is provided by the recently-developed domestic and foreign library utilization, and the detailed case were analyzed in the aspect of Library 2.0 service. Finally, the measures for improving the existing OPAC's interface and function in domestic library were suggested.

Statement of responsibility in bibliographical records plays a key role in clarifying intellectual responsibility of the work, and it also plays a role in making up access points. However, cataloging rules for the statement of responsibility mostly deal with the distinction between the principal role and minor roles. This becomes a problem because the responsibility type itself is more important than the order of the types. For this reason, in this paper I will explore improvements of the description methods of statement of responsibility by organizing the role indicators. Namely, using the role indicators more effectively than the current description methods do, we can collocate the dispersed statements of responsibilities. The role indicators can also be used for an author facet in information retrieval and can provide additional information for authority control.

추천 시스템은 다양한 분야에 적용되는 기술로서 활발한 연구가 진행되고 있고 기존 추천 시스템의 성능을 높이기 위해서 더욱 개인화된 차세대 추천 시스템의 필요성이 대두되고 있다. 본 논문은 하이퍼 개인화 범주에 속하는 사후 필터링기법을 사용한 실시간 상황 인식 추천 시스템을 제안한다. 실시간 상황 인식 추천 시스템은 사용자 행동과 계속적인 동기화로 현재 상황에 가장 적합한 추천 목록을 생성하기 때문에 사용자 기반 협업 필터링 (User Based Collaborative Filtering), 콘텐츠 기반 필터링(Content-based Filtering), 특이값 분해(Singular Value Decomposition)보다 훨씬 미래 지향적인 추천 시스템이다.
