  • 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.

  • This paper describes best-practices in lifting an image metadata standard to the Semantic Web. We provide guidelines on how an XML-based metadata format can be converted into an OWL ontology. Additionally, we discuss how this ontology can be mapped to the W3C's Media Ontology. This ontology is a standardization effort of the W3C to provide a core vocabulary for multimedia annotations. The approach presented here can be applied to other XML-based metadata standards.

  • We propose semantic model that is possible to apply for the bibliographic metadata of domestic digital library by analysing bibliographic metadata models like MARC, DC, MODS, JeromeDL's metadata model MarcOnt as the representative case of semantic digital library and FRBR model as the conceptual model.

  • Recently, the semantic web stands out in the next generation web. To realize the semantic web, the metadata integration is required between different metadatas on the web for metadata management. Otherwise, the integrated structure is needed to accommodate all of semantic, syntax and structure. RDF is one of the core technology and is more efficient framework for technology and interchange of metadata in the web, In this paper, for metadata management, we designed and implemented the RDF authoring system which converts each of metadata into RDF and makes it easy to manipulate and manage the different metadatas. For this, we researched about the RDF creation using Dublin Core metadata, the conversion of XML document into RDF, the RDF expression by N-Triple form and the integration of WSDL and RDF, and implemented the system on the lava platform. Basically, users using this system can integrate and manage metadatas easily even if they are not expert.

  • It is necessary to resolve the syntax, structure and semantic heterogeneity for sharing information resources. And the representative technologies are XML and Metadata. XML has been used to represent the syntax and structure, and metadata has been used to represent the semantic meaning of information resources. However, various metadata sets in one or more domains that have been developed by each independent organizations without any standards or guidelines, make it difficult to share their information resource. In this paper, we propose an interoperability framework (FSMI, Framework for Sharable Metadata Interoperability) on MDR (Metadata Registry) to increase the interoperability of XML encoded information resources between systems using different metadata sets.

  • The purpose of this study is to build a metadata set based on the semantic structure of the Korean studies research articles. For this purpose, we analyzed the related researches which suggested the semantic structure of the research articles, categorized the concepts of author keywords of the Korean studies research articles, and drew the metadata set of 16 elements from the results of the analysis and the categorization. The significance of this study is that it propose a semantic metadata configuration methodology which can reflect the scholarly sense-making of researchers in Korean studies. Especially, this study is significant because it reflects the keywords which was given by the actual researchers to examine the content characteristics of the Korean studies research articles.

  • 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.

  • The purpose of this paper is to develop the metadata on the information of research result in Science and technology and to design the domain knowledge structure using semantic web technology for further implementation. In this paper, we first analyze the existing theories and techniques related to the metadata in such fields as R&D research result, international standard, and semantic web. Then, we extract and group the relevant factors from Dublin Core, CERIF, and the research results for building the integrated metadata framework. Based on our proposed metadata, we design a domain knowledge structure which employs RDF/RDFS as knowledge representation tool. Therefore, we can implement the ontology which produce the 'intelligent' information service and improve the interoperability between the research institutions. Also, the metadata can be used as the basis for developing National R&D Performance Information, and in terms of research institutions, can be used as tools for managing the their own research results information systematically and consistently.

  • The total number of scholarly publications grows day by day, making it necessary to explore and use simple yet effective ways to expose their metadata. Schema.org supports adding structured metadata to web pages via markup, making it easier for data providers but also for search engines to provide the right search results. Bioschemas is based on the standards of schema.org, providing new types, properties and guidelines for metadata, i.e., providing metadata profiles tailored to the Life Sciences domain. Here we present our proposed contribution to Bioschemas (from the project "Biotea"), which supports metadata contributions for scholarly publications via profiles and web components. Biotea comprises a semantic model to represent publications together with annotated elements recognized from the scientific text; our Biotea model has been mapped to schema.org following Bioschemas standards.

  • World Wide Web is not more meaningless sea of information but is becoming the Semantic Web that provides many users with meaningful information. The starting point is the XML and metadata, RDF is a stopover which gives technique to relate arbitrary web resources. And now, the semantic and logic of web resources can be settled in the Ontology. A lot of educational multimedia web resources in Korea have produced their metadata with KERIS's KEM(Korea Educational Metadata). Therefore our country have to start the study of the semantic and logic in web resources. But, many researchers in Korea are more eager to study Dublin Core's DC and SCORM's LOM metadata specification than KEM. Thus the study of method about sharing and integrating these three metadata specifications should be performed before the study of semantic and logic in web resources in Korea. We design the Ontology to integrate these three metadata specifications and implement the prototype system using this Ontology. These three metadata have some elements that have same labels and meanings, and other elements have different labels and same meanings. To match these different labels which have same meanings, we adapted the one-to-one mapping technique in designing our Ontology. This designed Ontology was imported as "integrated schema" in our prototype searching system to integrate three different metadata in databases. Moreover we know that the more specific property design of class in Ontology was needed in order to provide users with more informed searching results such as synonym, antonym, hierarchy and associations.
