Recently, an increasing in quantity of multimedia data have brought a new problem that expected data should be retrieved fast and exactly. The adequate representation for the multimedia data is the key element for efficient retrieval. For this reason, MPEG-7 standard was established for description of multimedia data. In this paper, we propose a new approach to metadata production. The user can decompose a given content into units and easily annotate each unit by adding basic Information such as time, place, etc. as well as classification information such as event, relationship, etc. according to the MPEG-7 standard. The objective is to build automatically a pure semantic description; the nodes are the events and the links are the graphs which describe the relationships among the events. Finally, we have implemented an annotation tool(SMAT) for semantic description based on proposed technique and assess some of the experiment results. In conclusion, we ran say that the proposod annotation tool is characterized by two important proprieties : reusability and extendibility.

Recently, enterprise systems require the necessity of integration for data sharing and cooperation. As a methodology for integration, Service-Oriented Architecture for service integration and Master Data for integration of data, which is used for service, were appeared. This paper suggests a method that operates BP(Business Process) efficiently. We make XMDR(eXtended Meta Data Registry) as knowledge-repository to support the BP and construct data hubs to operate it. XMDR manages MDM(Master Data Management) to integrate the data, resolves heterogeneity between the data and provides relationship to the business efficiently. This is composed of MDR(Meta Data Registry), ontology and BR(Business Relations). MDR describes relationship between meta data to solve structured heterogeneity. Ontology describes semantic heterogeneity and relationship between data. BR describes relationship between tasks. XMDR data hub supports the management of master data and interaction of different process effectively.

We present new methods for an efficient retrieval of SGML documents. We define IDDL (index database description language) which is able to describe various information such as meta data, an indexing range, and the creation and manipulation of a database. In addition, we design IDQL (index database query language) that can deal with querying meta data as well as logical structure. Especially, the retrieval system based on IDDL and IDQL has been developed and implemented, and has been experimented on large number of documents. Experimental result shows that the proposed method provides the dynamic creation of an index database and a convenient retrieval environment.

Recently enterprises introduce EAI systems and legacy business which already obtained for data integration among legacy systems. EAI systems in cooperative transaction environment can be expected efficient retrieval as sharing and integrating. However existing legacy systems have to introduce particular EAI solution because it is difficult to adjust standard technology to EAI due to be managed independently without considering interoperability. For solving these problems we use metadata registry using data integration. Various types, semantic specification data heterogeneity and heterogeneity of systems, however, are occurred. Therefore retrieval system based on XMDR(extended Meta-Data Registry) for data interoperability in the web environment are proposed in this paper.

The Ministry of Education and Human Resources Development is propelling the estabilishment project of Internet-based School Library Information System for prepares a foundation of resource sharing and inter-school library loan, to improvement of DB construction's efficiency and to reduces a maintenance's burden of local information system. This system adapted the Dublin Core based DLS-I metadata to accommodate teh network resources and conventional MARC, it will be able to use easily. But this system does not consider metadata for reading instruction that the important element of school library service. Thus, this study is review to the necessity of description on the reading and reading instruction beside of bibliographic data, extracts a metadata elements of reading and reading school library information system(DLS-I metadata)

최근에 XML은 가독성과 확장성이란 장점 때문에 IPTV나 스마트 TV에서 서비스나 콘텐츠 정보 표현 및 검색을 위한 기술로 많이 사용되고 있다. 특히 TV-Anytime에서 정의한 스키마나 전송 프로토콜을 기본 규격으로 채택하고 필요한 기능을 수용하기 위하여 규격을 확장하는 경향을 보이고 있다. 그러한 장점에도 불구하고 XML은 텍스트 기반으로 정보를 표현함으로써 정보의 양이 커진다는 문제가 존재하고 이를 위하여 다양한 인코딩 방식이 제공되고 있다. 그러나 전송과정에서 문서를 독립된 조각으로 단편화하여 블록단위로 캡슐화하는 과정을 거치면서 인코딩 효율이 급격하게 떨어지게 되는 문제가 발생한다. 본 논문에서는 XML 문서를 캡슐화하는 과정에서 단편화를 통해 감소되는 인코딩 효율을 보완할 수 있는 블록 단위의 문자열 테이블 방식을 제안하고 실험을 통한 성능 분석을 제공하였다.

Recently, the web sites, such as e-business sites and shopping mall sites, deal with lots of catalog image information and contents. As a result, it is required to support semantic-based image retrieval efficiently on such image data. This paper presents a semantic-based image retrieval system, which adopts XML and Fuzzy technology. To support semantic-based retrieval on product catalog images containing multiple objects, we use a multi-level metadata structure which represents the product information and semantics of image data. To enable semantic-based retrieval on such image data, we design a XML database for storing the proposed metadata and study how to apply fuzzy data. This paper proposes a system, generate the fuzzy data automatically to use the image metadata, that can support semantic-based image retrieval by utilizing the generating fuzzy data. Therefore, it will contribute in improving the retrieval correctness and the user's satisfaction on semantic-based e-catalog image retrieval.

Modern systems have become more and more complex due to the ever-increasing user requirements and rapid advance of technology. As such, the frequency of accidents due to system design errors or failure has been increasing. When the damage incurred by accidents to human beings or property is serious, the underlying systems are referred to as safety-critical systems. The development of such systems requires special efforts to ensure the safety of the human beings operating them. To cope with such a requirement, in this paper an approach is employed in which we consider safety starting from the conceptual design phase of the systems. Specifically, a systems design method that can detect functional failure is proposed by utilizing meta-models and M&S methods. To accomplish this, the safety design data from international safety standards are first extracted and also a meta-model is generated using SysML (systems modeling language). Then, a SysML-based system design method is proposed based on the use of the developed meta-model. We also discuss how the safety requirements can be created and verified using a simulation method. Finally, through a case study in automotive design, it is demonstrated that the detection of a functional failure and the verification of a safety requirement can be accomplished using the SysML-based M&S method. This study indicates that the use of meta-models can be useful for collecting and managing safety data and that the meta-model based M&S method can make it possible to satisfy the system requirements by reducing the design errors.

Recently medical service environment, the clinical information exchange which contribute to medical safety, promotion of service quality and patient's convenience, efficiency of medical procedures and medical management is essential medical service model. But, practical exchange of clinical information which variation of information level, absence of standardization system, build of heterogeneous information systems is difficult in each medical institute. In this paper, We analyzed the related technical standardizations and the models of clinical information exchange. So, we designed the clinical information exchange system based on the ideal lazy response model which is aimed at vitalizations the exchange of clinical information under domestic law environment. In case of exchange the clinical information, we separate CDA document flow from metadata flow. As a experimental result we acquired 24% improved performance compared with existed system based on the lazy response model.
