    Abstract
    Discusses the varieties of link information on the WWW, how the Web differs from conventional hypertext, and how the links can be exploited to build useful applications. Specific applications presented as part of the ParaSite system find individuals' homepages, new locations of moved pages and unindexed information

    Abstract
    This is the first comprehensive book on hypermedia nd the WWW that icludes features of the 2nd generation systems. Definitions, history, current technology and problems, leading-edge initiatives, future applications, all these are seen as an unfolding of a millenial communication medium that is not serving but involving even the non-technical person in a very technical world. Much of the promise of hypermedia lies in its applications to education, and this receives prominence in the book. The new hypermedia system 'HyperWave' is described in detail. The book's vision, organization, and easy-to-read style make it suitable as a source for information for the practitioner and the general reader. It may also serve both as a reference book for researchers and as a textbook

    Abstract
    Navigating through hyperlinks within a Web site to look for information from one of its Web pages without the support of a site map can be inefficient and ineffective. Although the content of a Web site is usually organized with an inherent structure like a topic hierarchy, which is a directed tree rooted at a Web site's homepage whose vertices and edges correspond to Web pages and hyperlinks, such a topic hierarchy is not always available to the user. In this work, we studied the problem of automatic generation of Web sites' topic hierarchies. We modeled a Web site's link structure as a weighted directed graph and proposed methods for estimating edge weights based on eight types of features and three learning algorithms, namely decision trees, naïve Bayes classifiers, and logistic regression. Three graph algorithms, namely breadth-first search, shortest-path search, and directed minimum-spanning tree, were adapted to generate the topic hierarchy based on the graph model. We have tested the model and algorithms on real Web sites. It is found that the directed minimum-spanning tree algorithm with the decision tree as the weight learning algorithm achieves the highest performance with an average accuracy of 91.9%.

    Abstract
    The reader of a hypertext document in a web environment, if maximum use of the document is to be obtained, must visualize the overall structure of the paths through the document as well as the document space. Graphic visualization displays of this space, produced to assist in navigation, are classified into four groups, and Heo and Hirtle compare three of these classes as to their effectiveness. Distortion displays expand regions of interest while relatively diminishing the detail of the remaining regions. This technique will show both local detail and global structure. Zoom techniques use a series of increasingly focused displays of smaller and smaller areas, and can reduce cogitative overload, but do not provide an easy movement to other parts of the total space. Expanding outline displays use a tree structure to allow movement through a hierarchy of documents, but if the organization has a wide horizontal structure, or is not particularly hierarchical in nature such display can break down. Three dimensional layouts, which are not evaluated here, place objects by location in three space, providing more information and freedom. However, the space must be represented in two dimensions resulting in difficulty in visually judging depth, size and positioning. Ten students were assigned to each of eight groups composed of viewers of the three techniques and an unassisted control group using either a large (583 selected pages) or a small (50 selected pages) web space. Sets of 10 questions, which were designed to elicit the use of a visualization tool, were provided for each space. Accuracy and time spent were extracted from a log file. Users views were also surveyed after completion. ANOVA shows significant differences in accuracy and time based upon the visualization tool in use. A Tukey test shows zoom accuracy to be significantly less than expanding outline and zoom time to be significantly greater than both the outline and control groups. Size significantly affected accuracy and time, but had no interaction with tool type. While the expanding tool class out performed zoom and distortion, its performance was not significantly different from the control group.

    Outlines the results of a pilot study designed to consider what constitutes a landmark in hypertext. Tests users' memories for locations visited on the WWW. Reports the results, and outlines a refined methodology for a new study. By understanding more about users' navigation through hypertext information space, the issue of recognition of informative materials on the WWW may be addressed

    Abstract
    Purpose - The purpose of this paper is to explore the application of post-structuralist theory to understanding hypertext and the World Wide Web, and the challenge posed by digital information technology to the practices of the information profession. Design/methodology/approach - The method adopted is that of a critical study. Findings - The paper argues for the importance of post-structuralism for an understanding of the implications of digital information for the information management profession. Originality/value - Focuses on an epistemological gap between the traditional practices of the information profession, and the structure of the World Wide Web.

    Abstract
    At a finer level, Amitay speculates about the use of language on the Web. The Web may be one large corpus of text, but she suggests that communities will express themselves by the conventions used for writing hypertext. It may be that new information technologies will spawn new communities.

    Abstract
    The World Wide Web (WWW) is one of the newest tools available to assist in the navigation of the Internet. As with other client/server network tools such as Gopher and WAIS, developments with the Web are in a dynamic state of change. Basically, WWW is an effort to organize information on the Internet plus local information into a set of hypertext documents; a person navigates the network by moving from one document to another via a set of hypertext links

    Abstract
    Weblogs are gaining momentum as one of most versatile tools for online scholarly communication. Since academic weblogs tend to be used by scholars to position themselves in a disciplinary blogging community, links are essential to their construction. The aim of this article is to analyze the reasons for linking in academic weblogs and to determine how links are used for distribution of information, collaborative construction of knowledge, and construction of the blog's and the blogger's identity. For this purpose I analyzed types of links in 15 academic blogs, considering both sidebar links and in-post links. The results show that links are strategically used by academic bloggers for several purposes, among others to seek their place in a disciplinary community, to engage in hypertext conversations for collaborative construction of knowledge, to organize information in the blog, to publicize their research, to enhance the blog's visibility, and to optimize blog entries and the blog itself.

    Abstract
    The concept of a system combining information in both textual and pictorial format was first suggested by Vannevar Bush in 1945. The present hypermedia system was originally developed by Tim Berners Lee at CERN in 1989 and provides access to brief documents, which are interlinked and contain text, images, sound and video. The system has become widely available through the WWW, which enables users to 'navigate' through related information. Recent developments include the ability to view objects in virtual reality and the automatic generation of document links
