Information integration of heterogeneous digital parts libraries or electronic pars catalogs is one of issues in B2B procurements. We need to provide an integrated view for multiple information sources. Utilization of ontologies as the metadata descriptions of the information sources can provide an integrated view. However, in order to integrate independently developed ontologies, the mismatches among them should be resolved. In this paper, we propose an ontology of meta-concepts, i.e. meta-ontology. The meta-concepts play the role of vocabulary to describe the parts library ontologies and provide well-established ontological semantics that helps the ontology modelers to consistently identify parts library concepts and systematically structure them. Consequently, the meta-ontology reduces the differences in the way the parts knowledge is interpreted and ensures the mismatches are confined to manageable mis matches, so that a software program can merge automatically. Modeling ontologies of mold and die parts libraries for B2B e-commerce is taken as an example to show how to use the meta-ontology. We also discuss how a parts library mediation system can automatically merge the well-structured parts library ontologies.

The paper discusses the nature of Knowledge Organization Systems (KOSs) and shows how these can support digital library users. It demonstrates processes related to integration of KOS like the Dewey Decimal Classification, $22^{nd}$ edition (DDC22) in DSpace software (http://www.dspace.org/) for organizing and retrieving (browsing and searching) scholarly objects. An attempt has been made to use the DDC22 available in Bengali language and highlights the required mechanisms for system-level integration. It may help a repository administrator to build an IDR (Institutional Digital Repository) integrated with SKOS-enabled multilingual subject access systems for supporting subject descriptors based indexing (DC.Subject metadata element), structured navigation (browsing) and efficient searching.

This study is to design a Semantic Navigation Retrieval System for Oriental Medicine Articles based on a XTM so that people can search and use them more effectively than before. Keywords extracted from articles are categorized 4 topics : herbs, prescription, disease, and action. Keywords analysis Ontology is modeled based on 4 topics and their relations, and then represented Topic maps. Next, Article analysis Ontology is consist of title, author, keywords, abstracts and organization Topics from metadata. Keywords and Article analysis Ontology were integrated through Keywords Topic. Korean Medical Article Retrieval System is optimistic in terms on search results supporting semantic navigation in the information service aspects and easier accessibility because all related information are semantically connected with each different DBs.

무한 웹 컨텐츠 환경에서는 사용자의 컨텐츠 선택을 용이하게 하기 위하여 메타데이터를 다양한 방법으로 수집할 수 있다. 그러나 한 가지 방법으로는 메타데이터의 수신이 제한적이고 풍부한 메타데이터 수신을 위해서는 다양한 방법을 이용해야 한다. 그래서 본 논문에서는 메타데이터 수집 방법들을 통합하는 장치를 제안하고, 통합 메타데이터의 품질 향상을 위해 통합과정에서 발생하는 중복 메타데이터의 필터링 방법을 제시 및 검증한다. 구체적으로는 현재 웹 상에서 다양하게 제공되고 있는 메타데이터 수집 기능들을 분석하고, 통합 장치의 개념적인 구조를 제시하며, 웹 상에서 많이 보급되고 있는 RSS Reader를 통해 메타데이터를 수집하고 이를 토대로 분석하여 중복 컨텐츠를 판단하는 방법을 제안하였다.

기존의 전자도서관 시스템에서 정보를 관리하는 시스템들은 각 정보원 혹은 자료의 특성에 따라 독립된 시스템을 사용하고 있어서 분야별 표준화 방법과 표현방법에 큰 차이를 보이고 있으며, 서로 다른 분야의 콘텐츠에 대한 상호활용은 거의 불가능하다. 본 논문에서는 서로 상이한 콘텐츠를 통합적으로 관리가 가능하도록 사용자가 직접 콘텐츠별 포맷 정보를 추가 또는 변경이 가능하도록 시스템을 설계하였다. 제안하는 시스템은 기존 콘텐츠 관리 시스템보다 사용자가 동적으로 사용할 수 있는 환경을 제공하기 때문에 경제적인 측면에서는 비용을 절감할 수 있는 콘텐츠를 선택할 수 있으며, 관리적인 측면에서는 콘텐츠 데이터 자원의 재활용성을 높일 수 있다.

We address an integrated multimedia framework based on a software agent platform for context-aware multimedia computing. We adopt the FIPA (Foundation for Intelligent Physical Agents) platform which provides agent communications and management mechanisms. In order to express context information, we use MPEG-21 metadata for describing user characteristics and usage environment. We encapsulate such context information as a FIPA message to be delivered between agents. Based on context information, appropriate multimedia content delivery becomes possible. We present our system implementation with a use case scenario and show that our proposed framework is effective for context-aware multimedia computing so that personalization of multimedia consumption can be possible.

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.

In the cloud environment, the company needs data integration and analysis to make decision and policy. If new system is added to this environment, a lot of time and cost is needed due to disparate properties among systems when data is integrated. Therefore, in this paper, we propose a DBaaS hub system for multi-database service. The DBaaS may require a different database and need data integration for relevant service. Using the ontology, we propose a metadata query to resolve the interoperability issues between data of DBaaS. The meta-query is not a query to access the real data, but the query for the upper level. This method provides data integration by accessing the data with the converted query through an ontology when we access the actual database.We also constructs a document-oriented database system using the metadata.

Previously, the International Council of Archives (ICA) provided the General International Standard Archival Description (ISAD(G)) and the International Standard Archival Authority Record for Corporate Bodies, Persons and Families (ISAAR(CPF)) for the systematic archival description by the Committee on Best Practice and Standards. Recently, the new conceptual model and ontology, which is called "Record in Context" (RIC), is being developed by the ICA Experts Group on Archival Description (EGAD). For developing the new archival standard, ICA EGAD has referenced the archival standards of Australia, Spain, and Finland, as well as the FRBRoo integrated model of the museum and library fields and the legacy ICA's descriptive standards. This study, therefore, examined these international trends on the archival descriptive standards and derived a number of suggestions for improvement. As a result, descriptive standards are changing from the guidelines for the standardized archival description to the upper conceptual model and ontology for the flexible archival description and sharing of archival metadata. There is a need to adapt the change of the information environment and promote cooperation among cultural heritage institutions.

In computer-based virtual lab, a bioscience researcher who wants to obtain bio information first uses a biodiversity-related database to retrieve information on species, ecology and distribution of an organism. The researcher also needs to access gene/protein databases such as GenBank or PDB to find information on the organism's genetic sequence and protein structure. Furthermore, the researcher should search for academic papers containing the information on the organism so that his research is based on comprehensive and accurate information. This series of activities often undermines research efficiency as it takes a lot of time and causes inconvenience on the part of researchers. To solve such inconvenience, we analyzed various methods for integrated search and chosen schema integration. In addition, we analyzed each databases and extracted metadata for designing schema integration. This paper introduces a biological information retrieval system(BIRS) using schema integration and it's interface that will increase research efficiency for bioscience.
