The systematic management of research data is vital because it increases research data's value for research reproduction, verification, and reusability. Standard metadata will play a key role in research data registration, management, and data extraction. Research data has various structural relationships, such as research, research data, data sets, and files, and associated with entities such as citations and research results. The study proposes an ontology model for research data management. It also suggests the application of ontology to NTIS. Previous studies, metadata standard analyses, and research data repository case studies were conducted.

The exponential growth of information on the web far exceeds the capacity of present day information retrieval systems and search engines, making information integration on the web difficult. In order to overcome this, semantic web technologies were proposed by the World Wide Web Consortium (W3C) to achieve a higher degree of automation and precision in information retrieval systems. Semantic web, with its promise to deliver machine understanding to the traditional web, has attracted a significant amount of research from academia as well as from industries. Semantic web is an extension of the current web in which data can be shared and reused across the internet. RDF and ontology are two essential components of the semantic web architecture which support a common framework for data storage and representation of data semantics, respectively. Ontologies being the backbone of semantic web applications, it is more relevant to study various approaches in their application, usage, and integration into web services. In this article, an effort has been made to review the research work being undertaken in the area of design and development of ontology supported information systems. This paper also briefly explains the emerging semantic web technologies and standards.

It is essential to have Context-aware technology for personalization recommendation services and the appropriate representation and definition of Context information for context-aware. Ontology is possible to represent knowledge freely and knowledge can be extended by inferring. In addition, design of the ontology model is needed according to the purposes of utilization. This paper used context-aware technologies to implement a user personalization recommendation service. It also proposed the context through OWL modeling for user personalization recommendation service and used inference rules and inference engine for context reasoning.

시맨틱 웹에 이용되는 웹 온톨로지 언어들로는 RDF/RDFS, DAML+OIL, OWL 등이 있으며, 현재 W3C에서는 OWL을 웹 온톨로지 표준 언어로 삼고 있다. 기존의 웹 온톨로지 문서들의 파서는 대부분 RDF를 기반으로 한 Triple 모델을 기반으로 하여 파싱한다. 그러나 OWL의 경우는 triple 형태로 변환시키면 OWL Full의 형태를 가지게 되고 OWL 온톨로지의 표현력과 데이터의 손실을 가져오게 된다. 따라서 OWL 문서의 파싱을 위하여 우리는 OWL Abstract Syntax를 이용하여 Tree 모델을 가지는 OWL 파서를 만들고자 한다. 본 논문에서는 시맨틱 웹에서 사용되는 웹 온톨로지들을 파싱하여 온톨로지 객체 모델을 생성해주는 기능을 가지는 온톨로지 파서를 설계, 구현하였다. 논문에서 설계한 온톨로지 파서는 RDF, DAML+OIL, OWL 웹 온톨로지 문서들을 파싱하여 온톨로지 객체 모델을 생성할 때, RDF 온톨로지의 경우는 Triple 모델 형태로 파싱을 하지만, OWL 온톨로지의 경우에는 OWL Abstract Syntax Tree 모델 형태로 파싱한 후, OOM으로 변환시켜준다. 이를 위해 웹 온톨로지 언어의 종류 구분과 OWL 온톨로지의 경우, OWL Full, OWL DL, OWL Lite의 서브 타입을 구별하는 기능도 추가하였다.

Objectives : This study aims to propose a processing method for dosage units of medicinal materials and the database schema to manage formula data in Korean medicine ontology. Methods : All dosage units of medicinal materials are collected from the seven textbooks that contain formula data of Korea medicine ontology. Dosages are converted to Arabic numerals and units that are frequently used are converted to representative units. Database schema is designed for processing and managing the formulas and medicinal materials with dosage units. Results : Seven representative units are selected out of 77 units. They will be used in the addition or subtraction of medicinal materials in a formula support system. The remaining units will be made available for references. Conclusions : EMR or chart programs used in clinical hospitals contain formula data that is already standardized. However, the formula data in Korean medicine literature and textbook is not refined, so it is necessary to process the dosages and units of medicinal materials to use in the formula support system. This result is a processing method to utilize the formula data of Korean medicine textbooks and it will be implemented this method in the established formula support system in the future.

In the display of virtual space, the degree of space virtualization cannot be judged only by the degree of material technology. Based on the non-material relationship, the virtual space that this research focuses on is a conceptual and ontological point of view (based on the conceptual and ontological viewpoints of non-material relations), including practical technical issues. The research on the characteristics of virtual space ontology not only has an impact on the space design of science fiction movies, but also becomes a powerful medium that brings changes to the world. In the future, there will be a large number of cases where fantasy things in science fiction movies are actualized. From this perspective, based on the study of several science fiction movies using virtual reality scenes, this paper puts forward a study on the representation characteristics of virtual space ontology. In addition, the study of the virtual reality is of great significance for verifying the possibility of virtual reality in the application of deep space technology in the future. At the same time, it provides reference value for the development of special effects film field from montage theory-based to Bazin theory-based expression, and contributes to the theoretical system of film space.

In an attempt to disseminate modernized Korean traditional housing (Hanok), a ten-year research project was initiated in 2010 by the Korean Government to reduce the construction cost, improve the facility performance, and automate the Hanok construction industry. To meet these objectives, various research areas, including public policies, planning methods, design standards, new building materials, construction standards, maintenance procedures, advanced project management tools, and integrated IT applications have been developed. In addition, comprehensive technologies developed were applied to the ten pilot Hanok buildings to validate the real-world performance as part of the research project. To further facilitate the digital transformation of the Hanok industry by using the research results, it is required to disseminate the developed technologies in an automated and standardized manner. In particular, it is crucial to systematize and manage the interoperability of various technical data and accumulated historical data for different business functions, especially within the highly fragmented industry. In this context, this paper proposes an ontology-based Hanok information dissemination platform to enable industry-wide automated knowledge and information sharing. The system architecture, standardized historical database, and advanced analytics based on ontology web language (OWL) for the Hanok industrialization platform are introduced.

According to the widespread use of ontology documents, a management system which store ontology data and process queries is needed for retrieving semantic information efficiently. In this paper I propose a storage schema that stores and retrieves semantic web documents based on RDF/RDFS ontology language developed by W3C in a relational databases. Specially, the proposed storage schema is designed to retrieve efficiently hierarchy information and to increase efficiency of query processing. Also, I describe a mechanism to transform RQL semantic queries to SQL relational queries and build up database using MS-ACCESS and implement in this paper. According to the result of implementation, we can blow that not only data query based on triple model but also query for schema and hierarchy information are transformed simply to SQL.

With emerging the Internet of Things (IoT) paradigm, the sensor network and sensor platform technologies have been changed according to exploding amount of sensors. Sensor Registry System (SRS) as a sensor platform is a system that registers and manages sensor metadata for consistent semantic interpretation in heterogeneous sensor networks. However, the SRS is unsuitable for the IoT environment. Therefore, this paper proposes sensor registry data model to register and manager sensor information in the IoT environment. We analyze Semantic Sensor Network Ontology (SSNO) for improving the existed SRS, and design metamodel based on the analysis result. We also build tables in a relational database using the designed metamodel, then implement SRS as a web application. This paper applies the SSNO and sensor ontology examples with translating into the proposed model in order to verify the suitability of the proposed sensor registry data model. As the evaluation result, the proposed model shows abundant expression of semantics by comparison with existed models.

With the development of multimedia and network technology, the production of multimedia contents is rapidly increasing. Meanwhile, the technology to search and use the contents is still insufficient. There are standards for multimedia contents to address the problem, but they cannot fully support diverse multimedia data types or ensure their interoperability. In this paper, an ontology-based content search system is proposed to ensure the interoperability of multimedia contents. The ontology is configured by presenting the rules for it using the schema structure of the multimedia description scheme (MDS) of MPEG-7. Based on this ontology, the association of the multimedia data is expanded to design an access system that allows semantic search.
