    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
    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
    Natural language generation techniques can be used to dynamically produce hypertext dynamic catalogues on the Web, resulting in DYNAMIC HYPERTEXT. A dynamic hypertext document can be tailored more precisely to a particular user's needs and background, thus helping the user to search more effectively. Describes the automatic generation of WWW documents and illustrates with 2 implemented systems

    Abstract
    Richer graph models permit authors to 'program' the browsing behaviour they want WWW readers to see by turning the hypertext into a hyperprogram with specific semantics. Multiple browsing streams can be started under the author's control and then kept in step through the synchronization mechanisms provided by the graph model. Adds a Semantic Web Graph Layer (SWGL) which allows dynamic interpretation of link and node structures according to graph models. Details the SWGL and its architecture, some sample protocol implementations, and the latest extensions to MHTML

    Abstract
    We present a declarative language for the construction of hypertext views on databases. The language is based on an object-oriented data model and a simple hypertext model with reference and inclusion links. A hypertext view specification consists in a collection of parameterized node schemes which specify how to construct node and links instances from the database contents. We show how this language can express different issues in hypertext view design. These include: the direct mapping of objects to nodes; the construction of complex nodes based on sets of objects; the representation of polymorphic sets of objects; and the representation of tree and graph structures. We have defined sublanguages corresponding to particular database models (relational, semantic, object-oriented) and implemented tools to generate Web views for these database models

    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

    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
    A materialized hypertext view is a hypertext containing data coming from a database and whose pages are stored in files. A Web site presenting data coming from a database is an example of such a view, where the hypertext pages are HTML files. Even if the most popular approach to the generation of such sites is the virtual one, there is also a rationale for a materialized apporach. This paper deals with the maintenance issues required by these derived hypertext to enforce consistency between page content and database state

    Abstract
    Der vorliegende Beitrag zeigt auf, wie sich Neue Medien zur Verbesserung der Qualität der universitären Lehre einsetzen lassen. Exemplarische Vertreter der Neuen Medien sind in diesem Zusammenhang vor allem Hypertext und das auf Hypertext basierende World Wide Web, das dem Internet seit Beginn der Neunziger Jahre zu dem enormen Popularitätsschub verholfen hat. Das WWW bringt nicht nur die vielbeschworene 'Informationsflut' mit sich, sondern es liegt durch das WWW auch ein Werkzeug vor, um Informationen und Wissen optimal zu organisieren und aufzubereiten. Exemplarisch wird an einem Online-Programmierkurs verdeutlicht, wie sich Informations- und Wissensressourcen mit Hilfe der Neuen Medien besser strukturieren und produktiver einsetzen lassen

    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.
