최근 정보기술이 발전함에 따라 전자거래가 증가되고, 시스템의 분산화가 빠르게 진행되면서 상호운용성의 중요성에 대한 공감대가 형성되고 있다. 그러나 적용분야와 이해관계자의 관점에 따라 상호운용성의 정의가 상이하여 특정 시스템에 요구되는 상호운용성의 수준이나 평가 방법에 관한 공감대는 여전히 부족한 실정이다. 예를 들어 국방 분야에서는 동일한 업무를 하는 관계 기관별로도 상이한 정의를 사용하며 상호운용성의 실질적인 시험평가는 정의와는 다소 무관하게 정보교환 능력 수준의 저차원적인 평가만을 수행한다. 본 연구에서는 다양한 상호운용성 정의를 수집하여 그 정의의 구성요소를 추출하고, 이들을 데이터 마이닝의 연관성 규칙 탐사 방법을 이용하여 새로운 상호운용성 정의를 제시한다. 이 정의를 기준으로 한국군에서 사용 중인 정의들과 비교 분석한다. 본 연구에서는 장바구니 분석 기법을 이용하여 민간 및 국방 분야의 상호운용성 정의 구성요소의 연관성을 찾아, 가장 일반적이고 범용적인 정의를 도출하였다. 이 결과는 상호운용성에 대한 정의와 수준 및 평가항목 등에 대한 다양한 이해당사자들의 합의를 도출하는 데에 도움을 줄 것으로 기대한다.

As evidenced through rapidly growing digital repositories and web resources, automatic metadata generation is becoming ever more critical, especially considering the costly and complex operation of manual metadata creation. Also, automatic metadata generation is apt to consistent metadata application. In this sense, metadata quality and interoperability can be enhanced by utilizing a mechanism for automatic metadata generation. In this article, a mechanism of automatic metadata extraction called ExMETA is introduced in order to alleviate issues dealing with inconsistent metadata application and semantic interoperability across ever-growing digital collections. Conceptual graph, one of formal languages that represent the meanings of natural language sentences, is utilized for ExMETA as a mediation mechanism that enhances the metadata quality by disambiguating semantic ambiguities caused by isolation of a metadata element and its corresponding definition from the relevant context. Hence, automatic metadata generation by using ExMETA can be a good way of enhancing metadata quality and semantic interoperability.

A TCS(Train Control System) is the core facility to ensure the safety and efficiency of train operations, it is difficult to have interoperability between the TCS suppliers. To ensure the interoperability between TCSs, there is a need for definition, validation and standardization on the system configuration, the functions of subsystems, the interface between subsystems an the system protocol. In this paper, we analyzed the completeness of the KRTCS(Korean Radio based Train Control System) specification, derived supplements what you need to apply the KRTCS specification to new urban lines.

The following research questions are examined in this paper. What hinders quality metadata generation and metadata interoperability? What kind of semantic representation technique can be utilized in order to enhance metadata quality and semantic interoperability? This paper suggests a way of handling semantic ambiguity for metadata generation. The conceptual graph is utilized to disambiguate semantic ambiguities caused by isolation of a metadata element and its corresponding definition from the relevant context. The mechanism introduced in this paper has the potential to alleviate issues dealing with inconsistent metadata application and interoperability across digital collections.

Nowadays, AEC industry tries to adopt BIM for low-carbon and eco-friendly building development. With increasing environment policies, many of global construction projects require the adoption of BIM for its many advantages. The advantages can be maximized with Open BIM since it can produce optimal results for various purposes of energy performance assessment. However there are some troubles in representation and property information in the process of Open BIM based energy performance assessment. To examine such troubles, this study focuses on differences between IFC of Open BIM and IDF format of Energy Plus known as the most accurate and diverse energy performance assessment. Two issues the study addresses are form representation and property information. The study figures out the different definition of IFC and IDF, and suggests the way of interoperability. The interoperability test of IFC for building energy performance assessment hope to develop of Open BIM based energy assessment.

Recently industrial control systems have been required to ensure intelligent, high tech automation, interconnection and interoperability demands. Therefore, there is a need to redefine the structure concepts of SCADA system for wind power. Also, at this time, the integrated management system is required for the distributed development of wind farms where are needed often interoperability features and exchange information between different wind farms, wind turbines or SCADA systems. In this paper, an integrated structural concepts for SCADA system are defined. Based on this definition of an integrated SCADA system, the basic designs are analyzed on physical layer, system layer and application layer which are corresponded to wind turbine controller, the SCADA server and the SCADA client, and implement HMI. Between the implementation SCADA server and the client, their normal functions were verified at the small scale wind energy test facilities.

Different CAx systems are being utilized throughout the product lifecycle due to the practical reasons in the supply chain and design processes. One of the major problems facing enterprises of today is how to share and exchange data among heterogeneous applications. Since different software applications use different terminologies, it is difficult to share and exchange the product data with internal and external partners. This paper presents a method to enhance the CAD model interoperability based on feature ontology. The feature ontology has been constructed based on the feature definition of modeling commands of CAD systems. A method for integration of semantic data has been proposed, implemented, and tested with two commercial CAD systems.
