국제적인 규모의 많은 행사, 그리고 전반적인 생활수준의 향상으로 인해 외국을 방문하는 관광객의 수는 비약적으로 늘어났다. 또한 전 세계적인 네트 인프라의 발달로 인해 해외여행 중 어디에서나 인터넷을 쉽게 접할 수 있게 되었다. 그러나, 발달된 컴퓨팅 환경 속에서도 각 나라 별로 쉽게 문서를 작성하는 데는 아직 많은 어려움이 존재한다. 자국어를 포함한 한 두개의 외국어를 이용하여 콘텐츠를 작성하는 것은 어느 정도 가능하다 할지라도 그 숫자가 두세개 이상인 경우는 콘텐츠 작성에 많은 어려움이 존재한다.(중략)한다.(중략)

The Semantic Web has the objective of developing universal media in which machine-processable semantic information can be represented and shared, and it is therefore important to distribute ontologies that represent this kind of semantic information to the Web and make them available to multiple parties. However, the current ontology authoring tools are not operating on the Web, which makes it difficult to distribute ontologies directly to the Web and to create and edit them collaboratively with other people. This paper proposes a framework that facilitates the ontology construction and sharing, realizing easy distribution of ontologies to the Web. Wiki is one of the frameworks for collaborative construction and sharing of knowledge on the Web, and Wiki contents consist of natural language texts and simple markup language for visualization. For better collaboration in creating and sharing ontologies, this paper suggests the Semantic Wiki that embodies the Semantic Web features to the existing Wiki system. The Semantic Wiki framework facilitates the collaboration in ontology co-authoring and sharing for people, and at the same time, makes it possible for the agent software to easily manage the ontology information. Eventually, the Semantic Wiki system accomplishes various tasks including the semantic view, the semantic navigation, and the semantic query.

Recently, by the interest of geographical information and the utilization field of geographical information diversifying. Various GIS(Geographic Information System) was built to manage geographical information efficiently. However, because of interoperability between geographic information system, OGC(Open Geospatial Consortium) standardized GML(Geography Markup Language) of the XML(eXtensible Markup Language) foundation in which an interoperability writes possible geographical information data. GML national standard is applied to various application fields at present, and the use is confirmed. In this paper, GML 3.2.1 encoding standard specification follows requirements of OGC recommendation, we designed GML document editing system using XML standard technology, and generated interoperability GML data.

This paper presents the design and the implementation of a MissCW(Multi user Interactive System for Synchronous Collaborative Writing). The document model DMDA(Distributed Multimedia Document Architecture) of MissCW consists of the logical structure, presentation style object, and mark object. The windows. The collaborative editor of this system proposes a structure oriented editing mechanism to combine distrbuted objects into one document. The middleware SOM(Shared Object Manager) maintains shared objects consistently and helps application programs use objects efficiently. The infrastructure of this system is a hybrid structure of replicated and centralized architectures, that is to maintain shared objects consistently inside of SOM and to reduce the overhead of network traffic. The central part is a virtual node which corresponds to the Object Controller of SOMwith the SOT(Shared Objet Table).

This paper proposes the design and implementation of HTML-based Intelligent help system for application developers and users. In existing help systems, developers had to write topics, index, and contents of whole document by themselves. Furthermore those files are linked to one project file, which is in previously compiled form, and user can't modify topics and index information of their help documents. Especially in RAD environments, even though new features or packages are additionally announced, still users should be able to access and replace new help documents with existing ones. But these procedures are very complex in real world. The proposed help system is designed to analyze existing HTML documents, extract help data with regard to user's interest and is facilitated to authorize help contents with the user interface. Removing inconvenience in implementing context-sensitive help contents with the user interface. Removing inconvenience in implementing context-sensitive help system is also considered. In conclusion the proposed system in this paper can be actually useful when adopted into any typical Java RAD such as Bluette for its help system.

This paper presents the efficient mechanisms for concurrency control and writing authority control in collaborative writing system are represented by the tree structures which consist of the logical objects and the content objects connected to the terminal objects of trees. For concurrency control, we adopted the approach to extend the multiple-granularity-locking-scheme. This scheme allows us to lock any objects at each level of the hierarchy. We also defined the locking compatibility table by analysing the operations applicable to any objects at each level of the hierarchy. We finally suggest the extended-multiple-granularity-locking mechanism which uses the locking compatibilility table for deciding to lock an object. This scheme gives the benefit to maximize the possibility of concurrent accessing to the shared objects. In addition, we suggest a mechanism for writing authority control which prohibits the Non-Group users from modifying the shared objects based on the concept of Group/Non-Group The proposed mechanism allows us to protect copyright very reasonably.

SMIL을 이용하여 텍스트, 이미지, 음성, 영상, 애니메이션 등의 다양한 멀티미디어 클립들을 시간적/공간적으로 자유롭게 배치하고, 다양한 멀티미디어 프리젠테이션을 구성할 수 있는 교육용 컨텐츠를 구현할 수 있다. 하지만, SMIL은 HTML이나 XML과 같이 태그를 사용하므로 이를 구현하기 위해서는 텍스트 입력이 가능한 메모장이나 워드프로세서 등을 사용하여 문서를 작성해야하기 때문에 그에 따른 각각의 태그와 속성을 모두 암기해야만 효율적인 컨텐츠를 제작할 수 있다. 그러므로 사용자 입장에서는 시간적인 면에서, 또는 비용면에서 비효율적인 방식이다. 본 논문에서는 멀티미디어 동기화 언어인 SMIL을 기반으로 한 교육용 멀티미디어 컨텐츠 및 멀티미디어 데이터를 누구나 손쉽게 제작하고 처리할 수 있도록 SMIL을 기반으로 하는 교육용 컨텐츠 저작 시스템을 개발하여 컨텐츠를 제작하는 사용자들의 번거로움과 불편함을 없애고 효율성을 높일 수 있게 하였다.

The availability and growth of the Internet offers users the opportunity to find information and data all over the world. The development of the WWW has made the Internet easier to use, both for finding information and for publishing it electronically. Because so much information is available, and because that information can appear to be fairly 'anonymous', It is necessary to develop skills to evaluate what you find. Every printed information resources you find has been evaluated in one way or another before you ever see it. But when you are using the WWW, none of this applies. There are no filters between you and Internet. In addition, the ease of constructing Web documents results in information of the widest range of quality, written by authors of the widest range of authority, available on an even playing field Excellent information resources reside along side the most dubious. This study discusses the criteria arid methods by which scholars and researchers in most fields evaluate print information, and shows how the same criteria and methods can be used to assess Internet Website document. This study applied seven criteria, that is essential Web document element, authorship, publishing body, point of view or bias, referral to other sources, verifiability and currency. All information, whether in print or by byte, needs to be evaluated by users for some objective criteria and methods mentioned above. If you find information that is 'too good to be true', it probably is. Never use information that you can't verity. Always remember that the best counterfeit looks the most like the real thing. Establishing and learning criteria and methods to filter information you find on the Internet is a good beginning for becoming a critical consumer of information in all forms.
