  • Many research efforts have made on various fields to develop a system which is able to process diverse data in terms of efficiency and accuracy as well as minimizing the error in data-processing. As known, it is obvious that procurement is crucial process for the plant projects due to its importance and impact on the performance. It is strongly required to develop an effective metadata system to assist optimal controlling data for the logistics discipline of procurement processes in plant projects. Therefore, the main purpose of this paper is to apply a metadata system for logistics of the plant projects. The suggested technical module is tested using sample data and evaluated its performance in terms of accuracy and running speed. The results of this research will be extended to the other processes of plant projects in order to achieve a ultimately process-based life-cycle plant project information management system

  • Keeping the semantic interoperability between different formats is very important for reuseing and consistently processing metadata. This article is to design common schema and KORMARC schema based on RDF schema. For this, common elements are made by comparison of Dublin Core elements and KORMARC fields. The schema of these elements is designed for construction of semantic interoperability, basing RDF schema specification and syntax specification. Eventually, the semantic interoperability between a number of metadata formats can be constructed by matching the common elements to each attribute of format. KORMARC schema is designed by the application of common schema.

  • Semantic libraries can be used for EDI messages to exchange by implementing the semantic dictionaries. This paper describes the design information of semantic libraries for the field engineers to implement the semantic dictionary using metadata. The components of semantic libraries are semantic elements, semantic units and mapping tables. The basic characteristics and design methods related implementing are proposed. Also the metadata semantic dictionaries including the components and rules are introduced.

  • In the Semantic Web, storage models are required to efficiently store and retrieve metadata and ontology represented using OWL that can provide expressive power and reasoning support. In this paper, we propose an OWL storage model that can store and retrieve many restrictions and semantic relations defined on ontology with metadata. In addition, we propose some methods and rules to improve query processing efficiency of the proposed storage model. The proposed storage model can store and process large amounts of ontology and metadata because it consists of tables based on the relational database. And the proposed model can quickly provide more accurate results to users because of performing two different types of ontology reasoning and using the prime number labeling scheme to easily identify hierarchy relationships between classes or properties. The comparative evaluation results show that our storage model provides better performance than the existing storage model.

  • This study develops metadata elements based on the FRBR model for effectively managing and retrieving intangible cultural heritage records. Since intangible cultural heritage has a logical layer from its concept to a physical record that realizes the concept and it can be expressed in diverse formats such as video and audio, it is necessary to represent such rich relationships. Therefore, this study suggests a set of metadata elements at each of the four levels (work, expression, manifestation, and item) the FRBR Group 1 presents.

  • The purpose of this paper is to introduce and discuss a newly-constructed metadata database system that facilitates the retrieval of faculty syllabi available on the Internet. This gateway system aims to provide users with one-stop access to syllabi posted by the faculty of the institutes of post-secondary education from all around the world. Several elements of the Dublin Core (DC) and other supplementary elements were used for cataloging the syllabi. The conceptual schema of all the selected elements of the syllabi was developed following the entity-relationship model. The metadata of the syllabi was then stored in a relational database system. Various searching and browsing interfaces were implemented to facilitate effective retrieval. The prototype, named as Gateway to Faculty Syllabi (GFS), is available at http:/Ais.skku.ac.kr/gfs/.

  • As digital preservation becomes increasingly important, interest in web archiving has correspondingly increased. The processes of web archiving depend on the types of acquisition methods employed, the organization and storage of data, their completeness, and their scope. This study develops metadata for intensive web archiving. Several web archiving projects are reviewed and analyzed. As a result, administrative metadata has been suggested in addition to the basic elements from the Dublin Core.

  • This study attempts to investigate the current practice of electronic resources in the academic libraries and to explore the changes of paradigm in the organization of information. It reviewed how academic libraries have acquired and organized electronic resources. It also investigated the library home pages of 30 academic libraries in order to identify the category of electronic resources, metadata, and linkage methods with various material types such as printed resources and theses. To perform extended functions of library catalogs, it is essential for academic libraries to manage the metadata of various resources together and provide enhanced access and linkage of related resources.

  • This study applied reference metadata recognition using bidirectional GRU-CRF model based on pre-trained language model. The experimental group consists of 161,315 references extracted by 53,562 academic documents in PDF format collected from 40 journals published in 2018 based on rules. In order to construct an experiment set. This study was conducted to automatically extract the references from academic literature in PDF format. Through this study, the language model with the highest performance was identified, and additional experiments were conducted on the model to compare the recognition performance according to the size of the training set. Finally, the performance of each metadata was confirmed.

  • Video documents which have audio-visual and other semantics information have complex relationship among media. While user requests for topic retrieval or specific region retrieval increase, it is difficult to meet these requests with the existing design methodology, In order to support the systematic management and the various retrieval capabilities of video document, we must formulate structural and systematic model on metadata using semantics and structural informations which are abstracted automaticallv or manuallv. This paper suggests generic metadata model with which we analyze the characteristics of video document, supports various query types and serves as a generic framework for video applications, we propose the generic integrated management model(GIMM)for generic metadata,, design video documents management system(VDMS) and implement it using GIMM.
