With the advent of distributed computing and Web service technologies, lots of users have been requiring services that can conveniently obtain and/or support well-assembled information based on Web. For this reason, we are to construct Automatic Linking Support Systems for generating Web-based integrated information and supporting retrieval information according to user's various requirements. Our system organization is based on client/server system. A server environment consisted of automatic linking engine that can provide lexical analyzing, query processing and integrated document generating functions, and databases that are made of dictionaries, image and URL contents. Also, client environments consisted of Web editor that can generate integrated documents and Web helper that can retrieve them via automatic linking engine and databases. For client's user-friendly interfaces, web editor and helper programs can directly execute by down leading from a server without setup them before inside clients. For reducing server's overheads, Parts of server's executing modules are distributed to clients on which they can be executing. As an implementation of our system, we use the JDK 1.3, SWING for user interfaces like Web editor and helper, RMI mechanism for interaction between clients and a server, and SQL server 7.0 for database development, respectively. Finally, we showed the access procedures of automatic document linking engine and databases from Web editor or Web helper, and results appearing on their screens.

The aim of this study was to discover the correlation between users cognitive style and their attitude towards evaluating the system. Postgraduate students cognitive styles were defined as Verbaliser/Imager and Wholist/Analytic, and the functionality and ease of learning features of a Web-based OPAC(Online Public Access Catalogue) system were evaluated using a combined evaluation methods: interviews for the preliminary survey, a questionnaire far the central data collection, and a psychometric approach for the judgement of students cognitive style using Ridings CSA(Cognitive Style Assessment) tool. Forty-four postgraduate student volunteers responded and data was analysed using SPSS(Statistical Package for Social Science) for Windows. The statistical analysis of each feature of the evaluation, the correlation between the variables, and the features were explored using Pearsons correlation coefficients(r). In exploring the effects of the cognitive styles of individuals, this study has failed to reveal a significant (P < 0.05) correlations in the interactive Web-based OPACs evaluation. It could be said that the contribution of cognitive styles to evaluating Web-based OPACs is likely to be weaker than that of non-cognitive (or demographic) variables.

인터넷과 통합된 멀티미디어 기술의 발전 및 초고속 통신망의 보편적인 사용으로 인해 유기적으로 통합된 멀티미디어 컨텐츠에 대한 웹 서비스의 필요성이 대두되었다. 이에 따라 1998년 W3C(World Wide Web Consortium)에서 제안된 XML(eXtensible markup Language) 기반의 통합 멀티미디어 표현 언어인 SMIL(Synchronized Multimedia Integration Language) 1.0이 발표되었고, 기능이 확장되어 2000년 9월 SMIL 2.0으로 최종 Working Draft안이 발표되었다. 본 논문에서는 웹 컨텐츠 제공자 및 개인 사용자에게 SMIL 컨텐츠 저작을 위한 자동 생성 모듈 및 전용 저작 도구를 제공하고, SMIL 컨텐츠 데이터베이스 서버 및 재생기와의 통합으로 원활한 SMIL 컨텐츠 서비스 환경을 제공하는 통합 멀티미디어 시스템의 설계 및 구현을 제시하였다.

As the semantic web receives higher concern with an intensified necessity in these days, the research on the ontology as its core technology has been carried out in various fields. The ontology has been adopted as an alternative to work out lots of problematic issues resulted from the insufficient vocabulary selection rules in folksonomy, widely accepted under Web 2.0. Therefore the importance of research to complementarily consolidate the two disciplines, the folksonomy and the ontology, has been increased. Based on this idea this research proposes a system, which pulls out, using open services, the location information tags from folksonomy-based metadata, ultimately extracts, following location information analyses, spatial relationships among tags, and in turn automatically constructs self-correcting location information domain ontology. The system devised in this study will associate data derived from easily accessible folksonomy with meaningful and technological information from ontology.

Recently many of earlier GIS services are changing to the form of user-participated dynamic geoweb service like many new impressive web 2.0 services substitute for earlier old-fashioned web 1.0 services. Many relevant technologies are necessary to be developed so as to integrate a number of geospatial data and functions all around into the useful geoweb services. It is also necessary to make the integration easy and to cope with the rapid changes in geoweb environment. In this study, the trend of relevant geoweb technologies were reviewed before, and the development of open geospatial service platform were carried out. As a result, open 2D/3D map service engine, user-participated mashup engine, Open API search engine and so on were im plemented as the core components of that platform. The platform will be able to be used as the common platform among a number of applications in the fields such as public/private GIS integration, u-city projects and GIS/LBS services etc.

The purpose of this paper is to present the effective operation method of cyber home learning system 2.0. Cyber home learning system 2.0 which plays an important role to produce and share data of internet users establishing user-centered internet environment is recently introduced as web 2.0 is beginning to appear. This research is based on the case of the operation on cyber home learning system, research literature of web 2.0 as well as expert consulting and performance test. After doing this research, cyber home learning system 2.0 can bring enormous educational effect when it has online education using web-based discussion tool and long distance consulting linking with off line school education. Redundant system configuration, the distributed processing also may be provided by the service was smooth. Moreover, it demands monitoring team consisting of student, parents and teacher in order to provide developmental service.

최근 웹 2.0과 시맨틱 웹의 대중화와 더불어 Open API와 링크드 데이터를 이용한 시맨틱 웹 융복합(매쉬업) 서비스가 주목을 받고 있다. 다양한 링크드 데이터와 Open API들을 조합함으로써 새로운 서비스들을 쉽고 빠르게 만드는 것이 가능하기 때문이다. 하지만 사용자가 링크드 데이터와 Open API 서비스를 사용하기 위해서는 서비스 입력 값이나 출력값 등의 해당 정보를 얻어야 하며 이를 위해 링크드 데이터와 Open API를 제공해 주는 사이트를 직접 방문해야만 하는 불편함을 가지게 된다. 본 논문에서는 시맨틱 웹 매쉬업 서비스를 위한 통합 링크드 데이터 및 Open API 관리 시스템을 설계하고 구현하였다. 제안한 시스템에서 사용자는 사전 지식 없이 통합 관리 시스템을 통해 원하는 링크드 데이터와 Open API 서비스를 검색하고 실행할 수 있다. 또한 실행된 결과는 XML 형태로 저장되어 추후 매쉬업 시 재사용이 가능하도록 한다.

In this paper, we design and implement the UCC services prototype system for image and video. The proposed system consists of the two components such as the multimedia processing subsystem and the metadata management subsystem. It provides the API to UCC service developers. The multimedia processing subsystem supports the media management and editing of image and video, and the streaming services of video. The metadata management subsystem supports the metadata management and retrieval of image and video. The reply management and script processing of UCC are given in the subsystem.
