- 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
- 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
- Most existing hypermedia authoring systems are intended for use on desktop computers. These systems are typically designed for the creation of 2D documents and therefore employ 2D authoring mechanisms. In contrast, authoring systems for nontraditional multimedia/hypermedia experiences for 3D virtual or augmented worlds focus mainly on creating separate media objects and embedding them within the user's surroundings. As a result, linking these media objects to create 3D hypermedia is a tedious manual task. To address this issue, we present an authoring tool for creating and editing linked 3D hypermedia narratives that are interwoven with a wearable computer user's surrounding environment. Our system is designed for use by authors who are not programmers, and allows them to preview their results on a desktop workstation, as well as with an augmented or virtual reality system.

- Abstract
- Currently, adaptive educational hypermedia systems (AEHSs) are described using nonuniform methods, depending on the specific view of the system, the application, or other parameters. There is no common language for expressing the functionality of AEHSs, hence these systems are difficult to compare and analyze. In this paper we investigate how a logical description can be employed to characterize adaptive educational hypermedia. We propose a definition of AEHSs based on first-order logic, characterize some AEHSs resulting from this formalism, and discuss the applicability of this approach.

- Abstract
- The paradigm shift from the old system centered view to a user centered approach involves new tools needed for accessing library resources under the condition that the user's needs are taken into account. An end-user, who has only a little knowledge of classification systems or thesauri, understands little of the mode of the representation of contents and the use of authority lists. In addition, he will have difficulty in formulating his question in a precise manner. He needs to know better what the library proposes in order to define of what use it would be for him. Many studies have been carried out on the use of controlled vocabularies (classification, authority lists, thesauri) as searching devices. It is surprising to find that relatively little attention has been given to the role of these tools in filtering and browsing processes. We have developed a prototype named CATHIE (CATalog Hypertextuel Interactif et Enrichi) that supports such filtering and interactive reformulation features

- Abstract
- When the Web was invented, it was touted as a novel nonlinear medium for the written word. No longer would we be constrained by linear presentations! Hyperlinks would allow us to jump haphazardly from page to page, chapter to chapter, idea to idea! Texts would no longer need to run from beginning to end! This is misleading. A printed book is also multidimensional and potentially nonlinear. We can open it to any page, from any other page, for any reason. We can open several books at once. In fact, what makes a book special is its combination of linear structure (the order of the words) and nonlinear physicality (the bound papers). This linear/nonlinear duality is enhanced further by the index, which maps linearly sequenced pages in a nonlinear, informationally ordered structure (architecture). In truth, the online environment is crippled by an absence of linear structure. Imagine selecting a hard cover book, tearing off the covers, ripping pages into small pieces, and throwing them in a box. That box is like a computer file system, and the paper scraps are Web documents. Only one scrap can be retrieved from the box at a time, and it must be replaced before another can be accessed. Page numbers are meaningless. Global context is destroyed. And without page numbers or context, what happens to the index?
