- 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
- Producing an effective hyperdocument requires considerable work and a surprising diversity of skills. In addition to being good writers, the authors should have abilities in design, user-interfaces, testing, structuring and maintenance. This paper will analyse the work that goes into producing production-quality hyperdocuments and what the cost/benefits are. It is assumed that the reader, though not necessarily a hypertext expert, knows what hypertext is

- Abstract
- While hypertext is often claimed to be a tool that especially aids associative thinking, intellectual "work" involves more than association. So, questions arise about the usefulness of hypertext tools in the more disciplined aspects of scholarly and argumentative writing. Examining the phases of scholarly writing reveals that different hypertext tools can aid different phases of intellectual work in ways other than associative thinking. Spatial hypertext is relevant at all phases, while page-and-link hypertext is more appropriate to some phases than others.

- Abstract
- This paper introduces the notion of physical hypermedia, addressing the problem of organizing material in mixed digital and physical environments. Based on empirical studies, we propose concepts for collectional actions and meta-data actions, and present prototypes combining principles from augmented reality and hypermedia to support organization of mixtures of digital and physical materials. Our prototype of a physical hypermedia system is running on an augmented architect's desk and digital walls utilizing Radio Frequency Identifier (RFID) tags as well as visual tags tracked by cameras. It allows users to tag physical materials, and have these tracked by readers (antennas) that may become pervasive in our work environments. In the physical hypermedia system, we work with three categories of RFID tags: simple object tags, collectional tags, and tooltags invoking operations such as grouping and linking of physical material. In addition, we utilize visual ARToolKit tags for linking and navigating 3D models on a physical desk. Our primary application domain is architecture and design, and so we discuss the use of augmented collectional artifacts primarily for this domain.

- Abstract
- The disciplines of human-computer interaction, computer-supported collaborative work, information storage and retrieval, and artificial intelligence should complement one another in the new discipline of hypertext. This holistic view of hypertext focuses on links: links within a document (microtext), links among documents (macrotext), links among people (grouptext), and dynamic links (expertext). The principles and systems which are relevant to creating and accessing hypertext can be usefully presented under the heading of text, microtext, macrotext, grouptext and expertext. From text to expertext, people consistently use hierarchical structures, particularly hierarchical semantic nets, to organize information

- Abstract
- At the time being, there is a lot of different systems claiming to be either multimedia, hypermedia, or supporting collaborative, cooperative work. In this paper, a first attempt to clearify the notions of these concepts is tried. Multimedia content, hyperstructure organization and cooperative access will be identified as different features of an intelligent document. These features will be discussed under formal, information technology and implementation aspects

- Abstract
- Examines research literature on educational hypermedia design and divides the literature in 2 groups, 1 advocating no author control of the user's path through the material, the other advocating varying degrees of control. The no control researchers' work is determined to be lacking in audience and goals analyses as well as results evaluation while the researchers advocating control lack grounding in theory

- Abstract
- While the potential of hypertext as an information presentation medium is undeniable, its acceptance by users will be determined largely by its usability. Highlights 4 issues of relevance: reading from screens as opposed to reading from paper; reader behaviour; interface design variables such as display size and manipulation facilities; and user navigation. Existing research is reviewed and implications for the design of hypertext systems are discussed. Suggestions for future work are presented.

- Abstract
- Presents a conceptual model for hypermedia systems that, among ohter features, supports versioning, permits exploring and managing alternate configurations, maintains document histories, supports cooperative work and provides automatic propagation of version changes. In general, the model was designed to minimize the cognitive overhead imposed on the user by version manipulation. Presents a generic layered architecture for hypermedia systems with 4 major interfaces and shows how it matches the conceptual model

- Abstract
- Presents a study on hypertext examining the cognitive styles and spatial ability of users; the complexity of tasks; and the strucutre of information organization and the visualization of the structure. Future work on hypertext usability should emphasize task taxonomies along with longitudinal and ethnographic studies for a deep understanding of the interactions between users and hypertext
