Grid computing is an expanded technology of distributed computing technology to use low-cost and high-performance computing power in various fields. Although the purpose of Grid computing focuses on large-scale resource sharing, innovative applications, and in some case, high-performance orientation, it has been used as conventional distributed computing environment like clustered computer until now because Grid middleware does not have common sharable information system. In order to use Grid computing environment efficiently which consists of various Grid middlewares, it is necessary to have application-independent information system which can share information description and services, and expand them easily. Thus, in this paper, we propose a semantic information system framework based on web services and ontology for Grid computing environment, called WebSIS. It makes application and middleware developer easy to build sharable and extensible information system which is easy to share information description and can provide ontology based platform-independent information services. We present efficient ontology based information system architecture through WebSIS. Discovering appropriate resource for task execution on Grid needs more high-level information processing because Grid computing environment is more complex than other traditional distributed computing environments and has various considerations which are needed for Grid task execution. Thus, we design and implement resource information system and services by using WebSIS which enables high-level information processing by ontology reasoning and semantic-matching, for automation of task execution on Grid.

In this paper, when vehicle inspection is made, the check way is recommended based on the intelligent and personalized in the workplace, education, and other space-time according to the current situation. These results increase productivity, reduce costs, and improve performance. So we designed vehicle inspection recommendation system using ontology. Recommendation method is that components connected concept are shown according to weight value. if components are connected with other concept, the components are extended.

온톨로지는 시맨틱 웹의 핵심 기술 요소로서 지식을 개념화하고 명세화해서 의미론적 지식체계를 구축한다. 온톨로지는 개념적 모델링(Conceptual Modeling)을 통해 실제 세계의 지식(Real World Knowledge)을 표현하는 중요한 수단으로 제안되었고, 수많은 정보에 대한 지식관리를 효과적으로 수행할 수 있는 토대를 제공한다. 본 연구에서는 연구과제회의를 대상으로 온톨로지를 설계 및 구축한다. 과제 진행에 수반되는 다양한 회의와 관련자료는 과제의 성공적인 수행을 위해 반드시 관리되어야 한다. 일반적으로 회의에서 참석자들 사이에 정보 공유 및 자료 검색이 어렵고 회의일정 조정이 번거로우며 회의자료 관리가 체계적이지 못하다. 따라서 연구과제 진행과정의 회의와 관련자료들을 분석/분류해서 개념적 모델링을 통해 연구과제회의 온톨로지를 구축하고자 한다. 향후 이를 활용하여 지능형 반응 공간에서 회의 관리 및 서비스 제공을 할 수 있다.

시맨틱웹의 목적은 메타데이터의 개념을 적용하여 웹문서에 시맨틱 정보를 덧붙여, 웹에 있는 정보를 컴퓨터가 이해할 수 있도록 하는 것이다. 이를 가능하게 해주는 핵심 기술로 웹 온톨로지 언어 (OWL : Ontology Web Language)를 들 수 있다. 그러나 온톨로지 언어가 표현하는 객체들과 그들 사이의 관계는 복잡한 논리들로 얽혀 있어 언어에 익숙하지 않은 사람에게는 온톨로지 개발이 쉽지 않다. 본 논문은 개념 모델링을 위한 방법으로 가장 잘 알려진 EER 모델링만으로 복잡한 논리적 구조로 인해 작성하기 어려운 OWL 코드를 자동 생성하는 편집 도구를 설계한다. 특히 전자 카탈로그 도메인에 특화하여 자주 요구되는 특수한 개념들에 대한 모델링 요소를 추가하여 표현할 수 있게 하였다. 이는 온톨로지 개발자들의 시간과 어려움을 크게 감소시킬 것이며, 상품온톨로지 제작에 특히 유용할 것이다.

Geospatial information, which is one of social overhead capital, is predicted as a core growing industry for the future. The production of geospatial information requires a huge budget, so it is very important objective of the policy for geospatial information to prevent the duplication of geospatial projects. In this paper, we proposed a semantic search system which extracts possible duplication of geospatial projects by using ontology for geospatial project administration. In order to achieve our goal, we suggested how to construct and utilize geospatial project ontology, and designed the architecture and process of the semantic search. Moreover, we showed how the suggested semantic search works with a duplicated projects search scenario. The suggested system enables a nonprofessional can easily search for duplicated projects, therefore we expect that our research contributes to effective and efficient duplication review process for geospatial projects.

Recently, trends of information technology development include offerings of service for personalization, intelligence, and convergence. The research suggested a new tour system that tourists can make their tour packages by applying Semantic Web technology. The system includes ontologies and inference rules for offering intelligent and personalized service. Our system called MYT (Make Your Tour-package) was successfully demonstrated by employing realistic scenarios. Current version of the MYT system needs manager's intervention to link and integrate automatically ontology subsystem and Web service. In further study, the MYT will be extended to the system including a component integrating automatically subsystems and a component capturing and processing context data from RFID/USN.

In this paper, we introduce the general way for producing context information to support context-aware applications. It can fetch raw data from the service environments, translate it to reasonable context information, and provide to multiple applications. It is designed originally for the ubiquitous computing middleware and based on the ontology processing model. Automated service applications can use this system as the form of libraries or of web services for deciding its semantic cause of action.

In this paper we describe Task-Based Problem Solving Adapters (TPSAs) for modeling a humam solution (through activity-centered analysis) to a software solution (in form of computer-based artifact). TPSAs are derived from the problem solving pattern or consistent problem solving structures/strategies employed by practitioners while designing solutions to complex problems. The adapters developed by us lead toward human-centeredness in their design and underpinning that help us to address the pragmatic task constraints through a range of technologies like neural networks, fuzzy logic, and genetic algorithms. We also outline an example of applying the TPSAs to develop a working system for assisting sales engineers of an electrical manufacturing firm in preparing indent and monitoring the status of orders in the company.

The purpose of this paper is to define the concept of KAD/KAM, furthermore is to establish my own idea on the knowledge related works in engineering domain for a next decade ahead. KAD/KAM is represented as "Knowledge Everywhere" based on the concept of ubiquitous computing in engineering domain. At the beginning of the paper, the definition of KAD/KAM is described. And the related technologies to realize KAD/KAM, such as augmented reality, ontology, data mining, and knowledge management, are introduced. The concept of KAD/KAM is still immature. But this will be a new paradigm to change entire engineering environment in near future.
