We have suggested three learning rules and implemented an experimental system that automatically restructures hypertext networks according to their user browsing behavior. The system applies link weights to the hypertext networks and updates these weights according to the learning rules. The learning rules are based on how often a particular hyperlink is being traversed and operate on strictly local information of link traversals. Changes in network structure are fed back to users by dynamic link ordering according to descending link weight. This approach is used collaborative filtering and navigation support techniques. The system has been investigation to be able to structure random hypertext networks into valid representations of their user browsing preferences in experiments.

A hyperlink on academic World Wide Web has started to be recognized as a form of collaborative communication network connecting individual researchers and research groups and expanding their collaboration relations by making possible easy and direct online contact among people or groups anywhere in the world. This paper describes the structure of academic hyperlinks embedded in universities' Web sites hosted at the 10 Asian countries and further, examines the association between the structure of the hyperlink network and collaborative communication pattern among those countries based on their frequency of co-authoring articles. This research found that the number of inter-hyperlinks among universities' Web sites was significantly correlated with the frequency of co-authored articles across the 10 countries.

The present study positively analyzed the hyperlinks of 32 web sites with the purpose of analyzing the hyperlink network structure of web sites for each domestic library type. After collecting the hyperlink data using the crawler, we analyzed the overall characteristics of the websites in the network based on the characteristics of the library. The results are as follows. 1) Among all analyzed libraries, Yonsei scored the highest in degree centrality, betweenness centrality, closeness centrality, and eigenvector centrality. 2) By library type, Sejong for national library, Seoul for public library, and Yonsei for college library appeared an influential a relatively. Based on these analysis results, the present study will be utilized as basic data for establishing an operation strategy that improves the efficiency and effectiveness of library web sites in the future.

MICE (Meetings, Incentive trip, Convention and Exhibition & Event) industry is a multifaceted industry with a variety of stakeholders including the public and private sectors, and PCOs (Professional Convention Organizers) play a mediating role in communicating opinions of the stakeholders. For enhancing their reliability and awareness, PCOs have their stakeholders' hyperlinks on the websites. This study attempted to analyze the hyperlink networks among PCOs (Professional Convention Organizers) and their stakeholders so as to understand the MICE industry ecosystem and find out whether the network structure of PCOs' shows different levels of hyperlink use with their stakeholders' websites based upon PCO's performance and size. The results showed the hyperlink network of MICE industry and that the bigger PCOs have higher centralities in the network.

A number of previous studies have maintained that information technologies, due to their ability to overcome distance, can nurturing an innovative class of polycentric urban configurations, i.e., network cities. The present study intends to clarify whether any network relationship has recently been emerged among Korean cities by the advancement of information technology. The analyses focused on the geography of Korean national domains (.kr domains), and the hyperlink associations among three major types of domains, namely commercial, academic, and organizational domains. The study findings altogether indicate that the advancement of global economy and information era appears to be enhancing, rather than reducing the status of primate city. Seoul dominates the entire nation, forming an enclave in the production and consumption of information. Only the domains of educational institutes show network-like relations among local centers to a certain extent. The paper concludes with a discussion on the implications of the findings for future research and ‘spatial’ policy measures.

대학 내 기관별 웹페이지의 방문자 패턴을 분류하고, 하이퍼링크에 따른 네트워크 분석을 통해 방문자수와의 연관성을 연구하였다. 웹페이지 언어에 따라 영문 홈페이지는 공통적으로 낮은 방문 패턴을 보였으며, 단과대학이 개별 학과에 비해 높은 방문자수를 보였다. 웹페이지 하이퍼링크의 중심도(Centrality) 분석에서는 사이중심도(Betweenness centrality)를 정도(degree)로 정규화한 값이 방문자 수의 상한 값에 대응되는 현상이 발견되었다. 홍보효과를 위해 홈페이지 내용, 구조 설계뿐만 아니라 웹 상에 적절한 노출 전략도 도움이 됨을 알 수 있었다.

In order to improve organizational performance, organizations should make a knowledge management system to share, distribute, and create related knowledge effectively in the operational process. It is not too much to say that organizational performance depends on the level of network and networking for the use of knowledge among the agents. Theoretically, a web portal is known as a useful instrument not only to link among the actors who have a specific interest and purpose but also to promote social networking which creates new knowledge relevant to user's environment. In the context, this article explored policy implications of building and operating government portals by analysing the efficacy of the "Innovative Portal", which the Korean government had opened to diffuse its innovation activities and to improve organizational innovation capacities in 2005, in innovation process from the knowledge management perspective. In particular, this study tried to identify how did the "Innovation Portal"influence network and networking of innovation knowledge using hyperlink network analysis method.

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.

The visitors' patterns of the homepages in university were classified and analyzed with the network analysis based on the hyperlinks. The numbers of visits to English web-pages were proportional to those of Korean with much less counts. The larger count of visits was confirmed for the case of colleges than the departments, showing the upper boundary of visits from the plot with the Betweenness centrality normalized by the degree. For the better visibility, well-designed hyperlinks with the proper public relations were suggested based on the quantitative analysis of visitors' count.

네트워크 멀티미디어 서비스인 월드 와이드 웹(www)이 널리 확산되면서 인터넷 전자신문이 각광을 받고 있다. 그 이유는 전자신문의 최대 장점인 쌍방향 커뮤니케이션을 통해 그 날의 뉴스들을 음성, 동화상을 통해 실시간(Real Time)으로 제공하고 있으며, 하이퍼링크의 연결로 신문의 제한된 지면을 극복하고 많은 양의 정보를 독자들에게 제공할 수 있기 때문이다. (중략)
