  • This paper focuses on how the latest progress in digital media and technology affects the writing education environment. In the contemporary era, collecting numerous pices of information online, and arranging them to create new knowledge is important. There is also a need to seek new methods for writing education to stay in tune with the times. To that end, this paper suggests an open writing model using hypertexts. This writing model consists of a total of five stages, which are use of information, compilation of information, open mutual discussion, search of additional information and writing to recreate knowledge. The final outcome of such writing is writing using footnotes. By describing the gist of the keyword and adding numerous footnotes, such writing opens up an infinite possibility of re-creating information into new knowledge. This method can help university students who are accustomed to the digital society to proactively use information and improve multi-disciplinary communication skills required today. This author applied such a model to university writing education and found that more than 82% of the students were satisfied. Through the process of collaboration and recreation of knowledge in writing, learners found distinct benefits and noted their horizons had broadened. Given this effect, the open writing model using hypertexts is meaningful in that it forms a learning community that goes beyond a one-way feedback from instructor to student and instead nudges students to realize collective intellect. Moreover, it is meaningful in that it moves away from a top-down approach of the instructors passing down knowledge about writing and its rules, and towards a more proactive involvement by students in creating knowledge.

  • Recently, WWW(World Wide Web) has become a source of a large amount of information, and is now recognized not only as an information-sharing tool, but also as an information repository. Currently, the majority of documents on the web were created using HTML(Hypertext Markup Language). Although HTML is simple and easy to learn, its inherent lack of describing document structure makes it difficult to retrieve information effectively. One possible solution would be to convert such HTML documents into XML (extensible Markup Language) documents. This is a standard markup language for exchanging data on the web. It can describe a document structure freely by defining its own DTD (Document Type Definition). This makes it possible to integrate, store, and retrieve data on the web efficiently In this paper, we will propose a converter that automatically converts HTML documents with similar pattern into XML documents by analyzing the document structure and recognizing its path information.

  • 현재는 HTML(Hypertext MarkUp Language) 기반의 웹 페이지가 가장 널리 사용되고 있다. 그러나 사용자의 요구는 갈수록 높아져 2차원의 HTML로서는 표현하지 못하는 3차원 세계의 구현을 갈구하고 있다. 그래서 탄생한 것이 VRML(Virtual Reality Modeling Language)이며 현재 ISO 표준안으로 지정되어 있다. 사용자는 VRML로서 3차원 세계를 구현할 수 있지만, 가상세계의 규모가 커지고 복잡해지면서 문서편집기만으로 구축하기는 거의 불가능하다. 이런 이유로, 기존의 저작도구가 출현하게 되었고, 사용자에게 많은 편이를 제공하였다. 하지만, 이것 역시 몇 가지 문제점 (객체 설계 능력, VRML에 관한 지식 숙지, 일반 사용자에게 부담되는 비용) 때문에 VRML의 대중화를 방해되는 요소로 작용하고 있다. 그러므로 앞에서 제시한 문제점을 개선하기 위해, 사용자가 복잡한 가상객체를 디자인하는 것이 아니라 웹에서 이미 디자인된 객체와 개인자료를 합성하게 함으로써 일반 사용자에게 부담을 크게 줄일 수 있는 새로운 방법으로 개발했다. 그러므로, 본 논문은 인터넷 사용자라면 누구나 쉽게 가상공간을 제작할 수 있는 웹 기반의 저작도구인 WVRAT(Web based Virtual Reality Authoring Tool)의 설계 및 구현에 대해 기술한다.

  • While the WWW offers an incredibly rich base of information, organized as a hypertext, it does not provide a uniform and efficient way to retrieve specific information. When one tries to find information entering several query terms into a search engine, the highly-ranked pages in the result usually contain many irrelevant or useless pages. The problem is that single-term queries do not contain sufficient information to specify exactly which web pages are needed by the user. The purpose of this paper is to describe the employment of association rules in data mining for developing networks and computing associative coefficient among the terms. And this paper shows how the dynamic query expansion and/or reduction can be performed in information retrieval.

  • 최근의 웹 문서는 텍스트 위주의 구성이 아닌 이미지, 사운드, 동영상 등의 다양한 타입으로 구성되는 추세이다. 이에 따라 단순히 웹 문서 내의 단어 정보추출 만으로는 좋은 성능의 클러스터링을 기대하기 어렵다. 본 논문은 전통적인 문서 클러스터링 기법인 단어기반 클러스터링 기법의 취약점을 제시하고, 웹 문서간의 링크구조정보 중 동시인용 정보를 이용하여 웹 문서 클러스터링 성능향상의 가능성을 보이고자 한다. 실험에서는 네이버디렉토리 중 '자연과학' 범주에 포함된 문서를 대상으로 위의 두 가지 방식과 이 두 가지를 혼합한 단어-링크 혼합 클러스터링을 통해 기존의 방식보다 더 낳은 성능을 얻을 수 있었다.

  • 웹 문서의 가장 큰 특징 중 하나는 링크 구조이다. 이 링크들을 이용하여 전체 웹 문서를 커다란 하나의 네트워크로 구성할 수 있으며 이러한 네트워크를 분석함으로써 보다 중요한 문서, 보다 유용한 사이트를 찾아낼 수 있다. 전통적인 검색 모델인 벡터 모델의 성능 개선을 위해 이러한 링크 분석 기법을 활용하여 검색 정확도를 향상시키기 위한 방법을 제안한다. 또한 하이퍼 텍스트는 보다 정확한 키워드를 포함할 확률이 높으므로, 이를 가중치 계산에 적용하여 보다 정확한 결과를 산출한다.

  • An expert system for the diagnosis and indication of hypertension is implemented through HTML-based backward inference. HTML-based backward inference is performed using the hypertext function of HTML, and many HTML files, which are hyperlinked to each other based on the backward rules, should be prepared beforehand. The development and maintenance of the HTML files are conducted automatically using the decision graph. Still, the drawing and input of the decision graph is a time consuming and tedious job if it is done manually. So, automatic generator of the decision graph for the diagnosis and indication of hypertension was implemented. The HTML-based backward inference ensures accessibility, multimedia facilities, fast response, stability, easiness, and platform independency of the expert system. So, this research reveals that HTML-based inference approach can be used for many Web-based intelligent site with fast and stable performance.

  • The network structures of a hyperlinked environment can be a rich source of information about the contents of the environment and it provides effective means for understanding it. Recently, there have been a number of algorithms proposed analyzing hypertext link structure so as to determine the best authorities for a given topic or query. In this paper, we review the algorithm of mutual reinforcement relationship for finding hubs and authorities from World Wide Web, and suggest SHA, a new approach for link-structure analysis, which uses the relationships among a set of relative authoritative pages, a set of hub pages, and a set of super hub pages.

  • Since web-based tutoring systems are generally composed with passive and static hypertext, they could not provide adaptive learning environments according to learning ability of each student. In this study, we suggest an intelligent tutoring system, which grasps the learning state of student and provides each student with dynamic learning materials suitable to individual feature based on learning result. It is an agent based system, in which, courseware knowledge for learning is effectively constructed, the proper feedback according to learning assessment is inferred, and it is given to each student.

  • Web caches help to reduce latencies arising from slow networks through storing and reusing what was used before. Repeat access to a cached resource does not incur network latencies. However, resources that have never been used will not be found in the cache. Cache prefetching is a technique that helps to fill a cache with still-unused resources in anticipation that these resources will be used in the near future. Typically these unused resources are related to the resources that have been accessed in the recent past. While web caching exploits temporal locality, prefetching attempts to exploit spatial locality. Access to the prefetched resources will be cache hits, and therefore reduces the latency as perceived by the user. This paper reviews the cache infrastructure supported by the hypertext transfer protocol and discusses web cache prefetching in general, including Mozilla's prefetching infrastructure. It then classifies and reviews some prefetching techniques.
