In this paper, we have focused that the number of word in the web document affects definite clustering performance. Our experimental results have clearly shown the relationship between the amounts of word and its impact on clustering performance. We also have presented an algorithm that can be supplemented of the contrast portion through co-links frequency of web documents. Testing bench of this research is 1,449 web documents included on 'Natural science' category among the Naver Directory. We have clustered these objects by term-based clustering, link-based clustering, and hybrid clustering method, and compared the output results with originally allocated category of Naver directory.

The Korean oldbooks that represent the spiritual product of the ancestors in the form of physical shape are absolute need for retrieval and new evaluation through research and discovery. To earn Korean oldbooks that have these values, catalogue of Korean oldbooks and annotation book were used as secondery materials. But since there haven't been publications of Korean oldbook catalogue that can be used as Korean oldbook search engine, Korean oldbooks that has same title was valued differently by the different authors and defined differently according to bibliographic study. And there even has been a case when, even though there is same edition it was consider the only one. Therefor it can cause a lot of mistakes when you can't over look totally. So you can expert better results in structuring DB with computer then publicized catalogue of Korean oldbooks. But at this present time, since all of the DB that have been structured are not unified as one system and operated separately in their organizations, there has been a problem like creating different bibliographic information for same Korean oldbooks. In this study, as one of the solution to the problems of searching Korean oldbooks, we are making a plan to develop the unified retrieval system of Korean oldbooks using hypertext system. And with these finding, we are suggesting the further way of developing retrieval system of Korean oldbooks.

The information users of the middle of 1990s. who know the Internet as well as its useful information services, are now expecting the virtual library services. Especially the increasing demands on hypertext and hypermedia information in the internet settings have been centered on the W3 with the man-page information. In this manner, the paper describes the access methods with brief concepts of the W3 and explains URLs and HTML. It also gives the retrieval layouts of unformatted data including images and sounds and then provides the information sources and software of W3 Clients and Servers in order to catch up the most recently post version of W3.

eLearning can be defined as an approach to teaching and teaming that utilises Internet technologies to communicate and collaborate in an educational context. This includes technology that supplements traditional classroom training with web-based components and learning environments where the educational process is experienced online. The use of hypertext as an educational tool has a very rich history. The advent of the internet and one of its major application, the world wide web (WWW), has given a tremendous boost to the theory and practice of hypermedia systems for educational purposes. However, the web suffers from an inability to satisfy the heterogeneous needs of a large number of users. For example, web-based courses present the same static teaming material to students with widely differing knowledge of the subject. Adaptive hypermedia techniques can be used to improve the adaptability of eLearning. In this paper we report an approach to the design a unified implementation framework suitable for web-based eLearning that accommodates the three main dimensions of hypermedia adaptation: content, navigation, and presentation. The framework externalises the adaptation strategies using XML notation. The separation of the adaptation strategies from the source code of the eLearning software enables a system using the framework to quickly implement a variety of adaptation strategies. This work is a part of our more general ongoing work on the design of a framework for adaptive content delivery. parts of the framework discussed in this paper have been imulemented in a commercial eLearning engine.

Because of today's rapid growth of digital contents market and many benefits of electronic book, many people have considerable interest in E-book. Furthermore multifarious consortiums take an active part in standardization of I-book, and many E-book tools have been provided by software manufactures all over the world. E-book tools include editor for production of E-Book, viewer for reading, and the like. Especially in E-book viewer, annotation function has to be Included to put arrangement, summation, recording, comment, emphasis and after comprehension to practical use. In this paper, a E-book viewer with annotation is designed according to the specifications of EBKS, Korean standard. The proposed viewer is aimed to implement in PDA with embedded Linux, but developed in Windows 2000 platform. Because development environment and application environment are different each other, Qt-Library and cross-compiler are used for cross-platform development. The viewer support various functions such as adjusting of font size, hypertext linking, retrieval of specific word, and so forth. And in addition to these basic functions, annotation function is designed for the viewer, which can be used for re-usage and sharing of important information.

Hyperlink is a directly followable reference within a hypertext document. With a help of it, we can get information conveniently and save the cost for obtaining content in internet. KISTI(Korea Institute of Science and Technology Information) applied the hyperlink to GTB(Global Trends Brief service). GTB gatehers quickly the latest information of science, technology and market which is necessary to policy maker, businessman and researcher. This report explained the method how applied hyperlink to GTB and showed the examples.

Knowledge organization is the way we humans understand the world. There are two types of information organization mechanisms studied in information retrieval: namely classification md clustering. Classification organizes entities by pigeonholing them into predefined categories, whereas clustering organizes information by grouping similar or related entities together. The system of the Internet information resources extracts a keyword from the words which appear in the web document and draws up a reverse file. Term clustering based on grouping related terms, however, did not prove overly successful and was mostly abandoned in cases of documents used different languages each other or door-way-pages composed of only an anchor text. This study examines infometric analysis and clustering possibility of web documents based on co-link topology of web pages.

In the distance education systems, there are limited things while performing educational activities because there are to be problems in structural features of the Web. HTTP, a connection-less protocol, performs requests of client, however, does not hold on the status. Thus, by features of the Web, it is difficult to hold on the connection of learners and trace information asked by learners. Moreover, these problems make impossible not only a learner's connection continuity but also on-line interaction among the learners in the distance education. This thesis developed CHTP, an connection-based hypertext transfer protocol, based on HTTP and a new platform of distance education in order to track activities of learners. The developed web extension platform will make it easy to build up system for being helpful in a distance education because this thesis proposes a standardized way in the protocol.

The problems of developing web based adaptive hypermedia for education using XML are discussed in this paper. We define two different markup languages using XML. The one structures the domain model and the another describes the user model. These language can be easily extended and authored, with the result of obtaining a simple methodology for data structuring in the field of web based educational adaptive hypermedia. Also, We have suggested three learning rules that automatically restructures hypertext networks according to their user browsing behavior. The user profile is contained in a user model, while the knowledge about the domain can be represented in the form of a concept based domain model. Accordingly.
