  • Most metadata quality measurement employ simple techniques by counting error records. This study presents a new quantitative measurement of metadata quality using advanced weighting schemes in order to overcome the limitations of exiting measurement techniques. Entropy, user tasks, and usage statistics were used to calculate the weights. Integrated weights were presented by combining these weights and were applied to actual journal article metadata. Entropy weights were found to reflect the characteristics of the data itself. User tasks presented the required metadata elements to solve user's information need. Integrated weights showed balanced measures without being affected by the influence of error elements, This finding indicates the new method being suitable for quantitative measurement of metadata quality.

  • Metadata standardization of resources, having a heterogeneous metadata structure for each presidential archive and presidential library and museum is preferentially required for utilizing and sharing presidential records. An integrated operation model of metadata to manage various types of presidential records is then needed. The purpose of this study is to create a design principle of integrated metadata, and to suggest relationships and attributes of metadata, needed for developing integrated metadata operation system on presidential records. The design principle includes "creation of relationship among presidential records", "design of each entity, applicable multiple entity data model", "design to describe various types of presidential records", "design to reflect lifelong management on records of holding institutes", and "designing hybrid metadata for long term preservation". Metadata element set consists of elements for common attributes with all types of presidential records for a unique attribute for a specific presidential record and for reference information among different records related to the production of presidential records.

  • Recently there has been a growing interest in the investigation and development of the next generation web - the Semantic Web. From the perspective of a information science, the next generation web - Semantic Web is a metadata initiative. It is reason that one of important stage of Semantic Web Construction is adding formal metadata that describes a Web resource's content and so people can find easy material using metadata. In this paper, 1 designed new application profile metadata architecture as a way to serve as interoperability between various open digital libraries using different information architecture in Semantic Web environment. Based on new application profile metadata architecture, 1 developed union metadata automatic generation and union search algorithm to integrate heterogeneous huge-scale metadata in the open digital library.

  • The intelligent video surveillance environment is a system that extracts various information about a video object and enables automated processing through the analysis of video data collected in CCTV. However, since the privacy exposure problem may occur in the process of intelligent video surveillance, it is necessary to take a security measure. Especially, video metadata has high vulnerability because it can include various personal information analyzed based on big data. In this paper, we propose a COP-Transformation scheme to protect video metadata. The proposed scheme is advantageous in that it greatly enhances the security and efficiency in processing the video metadata.

  • The advances in communication technology and the popularity of network have rendered the increment of demand and desire to digital contents, and a number of creative digital contents produced. According to the time of compilation and a production of raw data, and manners, the format of digital contents may be variable and there can be existed in many connection information about digital contents. Although there are many metadata for standardizing the digital contents, they do not consider for expressing the connection relation about digital contents. In this paper, we proposed the new metadata for expressing the connection information about digital contents. This metadata is compatible the metadata of dublin core out of international standard of digital contents. Our metadata can express the variable direct or indirect connection relation about digital contents by expanding the relation element of dublin core. Also, our system can provide more useful information since we develop a system for managing connection information of digital contents based on our metadata.

  • 본 논문은 범정부 엔터프라이즈 아키텍처(EA)의 메타모델을 UML 다이어그램을 이용하여 개선 연구에 관한 논문이다. 여러 공공기관과 기업에서는 '범정부 정보기술아키텍처 적용'이란 전자정부 로드맵 과제로 정보기술을 그들의 경영혁신을 위한 전략적 도구로 도입하였으며, 조직 전체의 최적화 및 통합, 조직의 진화관리, 조직업무의 효율성 및 효과성 등을 제공하는 방법으로 EA를 개발 및 적용하고 있다. 하지만 EA 프레임워크에서 제안하는 메타모델들은 단순한 네모 박스와 선으로 연결된 의미가 부족한 메타모델들을 제안하고 있다. 본 논문에서는 메타모델에 의미를 부여하는 작업으로 UML 다이어그램을 이용한 새로운 메타모델 다이어그램들을 제안한다. UML에서 사용된 의미를 가진 다이어그램을 범정부 엔터프라이즈 아키텍처의 메타모델에 적용함으로써 의미적인 메타모델의 다이어그램을 통해 보다 의미 전달이 용이한 메타모델로 사용되어 질 수 있을 것이다.

  • SOiVA는 양방향 동영상 서비스를 위한 TTA 정보통신 표준이다. SOiVA 서비스는 다양한 정보를 표현하기 위해 메타데이터를 이용하는데, 이 메타데이터에는 그 중요성 때문에 반드시 제 3자로부터 보호되어야 하는 내용이 포함되어 있다. 이 중 일부가 외부에 노출되거나 유실 조작될 경우 큰 문제를 야기할 수 있으므로 반드시 적합한 보안 시스템이 필요하다. 본 논문에서는 전자서명과 암호화 등의 기술을 이용해 SOiVA 메타데이터 보안 시스템을 설계하고, 타당성을 검증하기 위해 시스템을 구현하고 예제메타데이터에 대하여 시험하였다.

  • 최근 인터넷과 네트워크 기술이 급격히 발전함에 따라 대용량의 동영상 데이터에 대한 서비스 요구가 급격히 증가하고 있으며, 인터넷 사용자는 비디오, 오디오, 텍스트 등으로 표현되는 다양한 멀티미디어 컨텐츠를 쉽게 이용할 수 있게 되었다. 이러한 환경에서 동영상 컨텐츠의 저장, 교환 및 검색에 있어서 보다 나은 편리성을 요구하게 되었고, 이것은 동영상 데이터의 다양한 정보를 기술하기 위한 메타데이터의 중요성을 더욱 증대시키게 되었다. 그러나 이러한 서비스들을 데이터 포맷 및 서비스 종류에 따라 각기 다른 표준을 사용하고 있어 업계간 또는 서비스간에 다르게 표현되는 메타데이터 정보들을 통합 관리하기는 어려운 실정이다. 따라서, 이 논문에서는 기존의 메타데이터 관리 시스템의 이점을 수용하고, 이를 확장하여 각각의 표준에 따라 서로 다르게 표현되는 동영상 메타데이터를 통합 관리하기 위한 시스템을 제안한다.

  • The Information of Technology Trend is one of the critical factors for research activities. In addition, this information tremendously affects the decision-making process of Science and Technology Policy. However, metadata of this information has not gain much attention so far. This research suggests metadata element and encoding scheme that is based on NewsML and using metadata of domestic Information of Technology Trend service system. The result of this research provides the basic resources for developing standard metadata of Information of Technology Trend which is suitable for domestic information technology situation.

  • Geospatial interoperability has been pursued by propagating international standards and OGC standards. The NGIC, GeoConnection and other catalogue services are reviewed with aspect to metadata and search functions. Detailed metadata could be driven to users after finding what they want to have. Criteria for search were not fully overlapped with metadata, as simple and typical searches are prevailing. OGC catalogue service standards were made but catalogue services in Korea have been implemented in their own ways, not fully compliance-tested. Different domain technologies have been developed regardless of geospatial service, the relationship and integration methods between catalogue services and other core technologies are reviewed in the form of a pair table. Other issues in geospatial service were discussed in the level of raising issues.
