- Abstract
- Analyzes an abstract model for hypermedia pplications. The model, Labyrinth, allows: the design of platform-independent hypermedia applications; the categorisation, generalisation and abstraction of unstructured heterogeneous information in multiple and interconnected levels, the creation of personalisations in multiuser hyperdocuments for both groups and individual users and the design of advanced security mechanisms for hypermedia applications

- 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
- The rapid evolution of hypermedia technology makes it possible to access an immense volume of information in an educational setting. This research examines the relationship between individual differences (in particular, cognitive styles) and navigation strategies using a WWW-based hyper-media learning system. The hypermedia learning system was used at Sheffield University's Department of Information Studies. 20 Master students were pre-tested for their cognitive styles. Dependent variables included navigation patterns, selection of navigation tools, and reactions to the hypermedia system. the results indicated that students with differing cognitive styles and individual characteristics selected different access facilities and applied different navigation patterns. The implication of these findings and the role of individual differences in designing hypermedia-based learning systems are discussed

- Abstract
- The ease of linking and hopping from one text to another that we associate today with the World Wide Web was implemented in a different context prior to the Web. The creation of "hypertext" has a long and interesting history prior to the Web, as this article demonstrates. At the time it was issued, the HyperCard software application was expected to be the foundation of a widely-used new means of information organization. We can see now that the key ideas of hypertext were present in HyperCard, without the ease of use of subsequent World Wide Web features.

- Abstract
- The subject of this book is the relationship between people and interactive media. Written by one of the world's leading experts on this subject, this book explores how hypermedia, groupware, and networks change the way in which people, gropus and organizations work and interact. Its wide-ranging focus discusses the emergence of new technologies and demonstrates by considering real-life case studies the impact each has had on the way we view and interact with colleagues and information. With its emphasis on actual examples of usage, the author provides both practitioners and students with a fascinating glimpse of the future of these media and their applications.

- 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
- With the growth of hypertext and multimedia applications that support and encourage browsing it is time to take a penetrating look at browsing behaviour. Several dimensions of browsing are exemined, to find out: first, what is browsing and what cognitive processes are associated with it: second, is there a browsing strategy, and if so, are there any differences between how subject-area experts and novices browse; and finally, how can this knowledge be applied to improve the design of hypertext systems. Two groups of students, subject-area experts and novices, were studied while browsing a Macintosh HyperCard application on the subject The Vietnam War. A protocol analysis technique was used to gather and analyze data. Components of the GOMS model were used to describe the goals, operators, methods, and selection rules observed: Three browsing strategies were identified: (1) search-oriented browse, scanning and and reviewing information relevant to a fixed task; (2) review-browse, scanning and reviewing intersting information in the presence of transient browse goals that represent changing tasks, and (3) scan-browse, scanning for interesting information (without review). Most subjects primarily used review-browse interspersed with search-oriented browse. Within this strategy, comparisons between subject-area experts and novices revealed differences in tactics: experts browsed in more depth, seldom used referential links, selected different kinds of topics, and viewed information differently thatn did novices. Based on these findings, suggestions are made to hypertext developers

- Abstract
- This paper describes part of a university research project which aims to construct a design method involving interactive multimedia products for knowledge acquisition. The purpose of the method is to design truly interactive multimedia products (Vidalenc, 1997), and thus to introduce a new form of writing. This is built up by adopting a constructivist paradigm that is based upon a systemic view and upon a network approach such as proposed by the sociology of translation (Callon, 1986). All our reflections are indeed based on the differentiation between two levels of information: an internal level and a sensitive level (Bouzidi and Vidalenc, 1997). However we have chosen a common model, the object oriented model, which allows us to represent the elements belonging to each level. In order to prove the validity of this proceeding, a prototype is under preparation. It is founded on the transposition of a course, which deals with telecommunications and networks, into a multimedia teaching tool. To be able to build up the prototype, taking into account the usual steps (writing the requirement schedule, choosing the necessary technology, modeling, design, implementation and evaluation), and after that, to be able to measure the conception method, a stage of analysis and assessment of the present course is necessary. The analysis of the course must allow us to identify the conditions of the knowledge transfer and provide components for the requirement schedule of the hypermedia product. This is the main subject of our reflections

- Abstract
- A new computer-based writing environment is being developed which combines a hypertext 'ideas organizer' with a text editor. Compares 2 algortihms which could be used in such environments for turning networks of notes indicating ideas into linear draft documents. The algorithms are designed to produce a linear ordering of the notes which is acceptable to the writer as a first draft of the document. Reports on experiments to test their effectiveness. Subject were asked to create notes networks which were then linearized by the 2 algorithms. The resulting linearization created by hand, were assessed for textual organization. The experiments indicate that both algorithms produce linearizations which are acceptable as draft texts, that the best first algortihm is marginally superior to the hill climbing one, and that providing information to the algorithms about link types had little effect on their effectiveness. Concludes by describing an implementation of the best first algorithm as part of the Writer's Assistant writing environment

- 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
- This paper introduces the notion of context-aware mobile hypermedia. Context awareness means to take the users' context such as location, time, objective, community relations, etc., into account when browsing, searching, annotating, and linking. Attributes constituting the context of the user may be sensed automatically and/or be provided by the user directly. When mobile, the user may obtain context-aware hypermedia support on a variety of small and medium sized computing platforms such as mobile phones, PDAs, tablet PCs, and laptops. This paper introduces the HyCon (HyperContext) framework with an architecture for context-aware hypermedia. The architecture includes interfaces for a sensor tier encapsulating relevant sensors and represents the hypermedia objects in structures based on the XLink and RDF standards. A prototype called the HyConExplorer created with the framework is presented, and it is illustrated how the classical hypermedia features such as browsing, searching, annotating, linking, and collaboration are supported in context-aware hypermedia. Among the features of the HyConExplorer are real-time location-based searches via Google collecting hits within a specified nimbus around the user's GPS position. Finally, the use of scenarios for and evaluation of the use of the HyConExplorer in public school projects are discussed.

- 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.
