The purpose of this study is to identify and present the solution to the problems of KORMARC on Disc, which was produced by the National Library of Korea and is being distributed nationwide. Currently, KORMARC on Disc has reached the serious level of duplicates of input record, error on input data and noise of retrieval. Futhermore, input data is not in accordance with KORMARC Rules for Descriptive Cataloging, thus generating many problems. Of all thing, since current MARC system itself is based on manual system, it does not correspond effectively to the online environment. Accordingly, in order to elevate the quality of KORMARC database, current problems must be resolved, at the same time, korea Machine Readable Cataloging must be modified into a format, more suitable to Machine Readable environment. Consequently, the current study analyzes and identifies problems of data in KORMARC on Disc, at the same time, it examines currently used KORMARC Format and Korea machine Readable Cataloging Rules for descriptive Cataloging as to provide easier usage and guidelines for accurate data inputs.

Our research goal has been the development of a domain independent natural language processing (NLP) system suitable for information retrieval. As part of that research, we have investigated ways to automatically extend the semantics of a lexicon derived from machine-readable lexical sources. This paper details the extraction of thematic roles derived from lexical patterns in a machine-readable dictionary.

Logistics movement using ships has been used for many centuries, but maritime accidents are still difficult to predict and they occur on a large scale. The International Maritime Organization (IMO) made it mandatory to install Electronic Chart Display and Information System (ECDIS) for safe seas, but S-57 standards applied to equipment were not updated over 30 years. In addition, it is difficult to keep the equipment up-to-date and revise standards as ships move around the world. In consideration of the limitations of S-57, the IHO developed the new standard as S-100 rather than an update of the S-57. In this study, the previously developed S-100 tool and S/W were configured as one platform and applied to the S-100 ECDIS. The platform conducts as the S-100 cycle and ecosystem from the creation of standards to release and practical use in ships. The hydrographic information standard is machine-readable as defined in S-100, and it has been validated that the latest standard can be applied using the Plug and Play (PnP) function without software system updates. It is expected that international organization such as the International Hydrographic Office (IHO) and the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) shall develop and release standards and mariners can easily apply the latest standards to equipment through the machine-readable platform.

In this paper, we propose an approach to generate machine readable context annotations for SPARQL Results. According to W3C Recommendations, the retrieved data from RDF or OWL data sources are represented in tabular form, in which each cell's data is described by only type and value. The simple query result form is generally useful, but it is not sufficient to explain the semantics of the data in query results. To explain the meaning of the data, appropriate annotations must be added to the query results. In this paper, we generate the annotations from the basic graph patterns in user's queries. We could also manipulate the original queries to complete the annotations. The generated annotations are represented using the RDFa syntax in our study. The RDFa expressions in HTML are machine-understandable. We believe that our work will improve the trustworthiness of query results and contribute to distribute the data to meet the vision of the Semantic Web.

이 논문에서는 데이터를 효율적으로 공유하기 위해서 제정된 ISO/IEC 11179 메타데이터 레지스트리(Metadata Registry, 이하 MDR) 표준에 관한 내용을 먼저 기술하고, 이 표준에 근거한 시스템간의 데이터 공유의 폭을 넓히기 위해서 W3C에서 개발한 시맨틱웹의 핵심기술과 웹온톨로지 언어(RDF/OWL)를 소개하고 마지막으로 기존의 인간가독형 MDR을 기계가독형으로 구축하기 위한 기본설계 초안을 RDF/OWL 기반으로 작성하였다. 앞으로 이러한MDR이 구축되어 널리 활용된다면 다양한 형태의 고급 정보서비스가 가능할 것으로 판단된다. 메타데이터 요소 정의, 온톨로지의 개념 및 메타데이터 스키마 정의가 기계가독형으로 통합된다면 이용자에게 더욱 정교한 맞춤서비스를 제공할 수 있을 것으로 기대된다. 미래의 과제는 시맨틱 기반MDR의 유용성에 대해서 실험연구를 통한 객관적 평가를 수행하는 것이다.

빅데이터 시대에 정형데이터 뿐만 아니라 비정형데이터를 분석하는 것이 중요한 과제로 대두되고 있다. 정부기관이 생산하는 공문서도 텍스트 기반의 대형 비정형데이터로 빅데이터 분석의 대상이 된다. 기관 내부의 업무효율, 지식관리, 기록관리 등의 관점에서 공문서 빅데이터를 분석하여 유용한 시사점을 도출해 나가야 할 것이다. 그러나, 현재 공공기관이 보유 중인 공문서의 상당수가 개방포맷이 아니어서 빅데이터 분석을 하려면 비트스트림에서 텍스트를 추출하는 전처리 과정이 요구된다. 또한, 문서파일 내에 맥락 메타데이터가 충분히 저장되어 있지 못하여 품질 높은 분석을 하려면 별도의 메타데이터 확보 노력이 필요하다. 결론적으로 현재의 공문서는 기계가독(machine readable) 수준이 낮아 빅데이터 분석에 비용이 많이 들게 된다. 이 연구에서는 향후 공문서가 기계가독 수준을 높이기 위해서는 공문서의 개방포맷화, 기안문 서식의 표준태그화, 자기 기술(self-descriptive) 메타데이터 확보, 문서 텍스트 태깅 등이 선행될 필요가 있다는 점을 제안한다. 첫째, 문서가 스스로를 설명하기 위해 추가되어야 하는 메타데이터 항목들을 제시하고 이 메타데이터들이 기계가독형이 되도록 문서파일에 저장하는 방법을 제안한다. 둘째, 문서 내용 분석 시 자연어 처리에만 의존하지 않고 행정 맥락에 따라 중요한 키워드를 미리 국제표준 태그로 마킹하여 기계가독형이 되도록 하는 방안을 제안한다.

One of the major problems on the design of an online database for machine readable data file is on the implementation of MARC format for communication with the Library of Congress or OCLC. Most of the cataloging data to make manual card catalogs are stored on magnetic tapes based on the MARC format at LC or OCLC and are sent to local libraries. Therefore, local libraries can avoid the expensive process of cataloging for the books they own. Instead, they can retrieve the necessary cataloging information from the tape and print out manual card catalogs. A problem with MARC is that it is not designed for databases, but for portability to be read at any type of computer. Therfore, it is not practical to use the format on the development of an online database as long as the database is developed in conjunction with a commercial powerful database package. In this paper a possible methodology to resolve the conflicts between the objective of DBMS and MARC is discussed. It is to satisfy the requirements from a commercial DBMS while leaving a room for MARC to communicate with LC and OCLC.

Authority control enables us to retrieve information accurately by coordination and cross reference of headings. It is considered that authority control is needed in machine readable catalogs as well as in conventional catalogs. Taylor, Maxwell and Frost divided automated authority control systems into major vendor and network systems then available into two groups. The first group was defined as a system that processes a library's machine readable catalogs on the tape against an automated authority file. The second group offers an online access to catalogs and authority records. This group was further subdivided into linked or integrated systems and unlinked systems. If authority work is shared with many libraries the costs can be considerably reduced and the quality of catalog data base can be controled by standardization of headings used in participating libraries. The NACO is a project for sharing of authority records started in 1977 by L.C. And LSP furthers the ability to share authority records. A project as the NACO is necessary not only in America but also in the other countries The responsible organizations for national bibliographies of the countries must take much interest in these matters.
