“…Educational hypertexts restrict the user's browsing within small portions of the hyperspace which are focused on a certain topic (lesson) and in this way reduce the risk that the user gets lost (Brusilovsky, 1992). In the context of educational hypertext it has been proposed (Böcker, Hohl & Schwab 1990;Hohl et al 1996;Brusilovsky, Pesin & Zyryanov 1993) to provide appropriate starting points for navigation, and local orientation by suggesting links from the current node which will be appropriate to follow (having in mind a specific goal node).…”

User Model User-Adap Inter

The development of user-adaptive systems is of increasing importance for industrial applications. User modeling emerged from the need to represent in the system knowledge about the user in order to allow informed decisions on how to adapt to match the user's needs. Most of the research in this field, however, has been theoretical, "top-down." Our approach, in contrast, was driven by the needs of the application and shows features of bottom-up, user-centered design.We have implemented a user modeling component supporting a task-based interface to a hypermedia information system for hospitals and tested it under realistic conditions. A new architecture for user modeling has been developed which focuses on the tasks performed by users. It allows adaptive browsing support for users with different level of experience, and a level of adaptability. The requirements analysis shows that the differences in the information needs of users with different levels of experience are not only quantitative, but qualitative. Experienced users are not only able to cope with a wider browsing space, but sometimes prefer to organize their search in a different way. That is why the user model and the interface of the system are designed to support a smooth transition in the access options provided to novice users and to expert users.

Modeling and User Adapted Interaction, vol. 6, Nos. 2-3, 1996 . 2 Published in User IntroductionBrowsing is a useful technique for retrieving documents from data-bases (Thompson & Croft, 1989).It has been widely applied recently as hypertext and hypermedia systems have become increasingly popular (Begoray, 1990). The main cognitive advantage of this technique is that users in general are better able to recognize the information they want than to characterize it in advance. The disadvantages of browsing are that it is easy to get lost in a complex network of nodes representing documents and concepts and that there is no guarantee that browsing will be as effective as a more conventional search. If it offers a rich set of links, the system is responsible for helping the users understand what the links mean, how they might be used, and how to find their way in the network. Without this kind of help, browsing can take on the aspect of the user finding her way in a maze, where she can become hopelessly "lost in (hyper)space" (Conklin, 1987). User modeling can help in supporting the user's navigation and information retrieval. A user model is an explicitly represented collection of data about the user which allows the system to adapt its options to the needs of the user. The intensive development in the field of user modeling during the last decade (Kobsa & Pohl, 1994a) makes it possible to consider it as a practical approach for ensuring user-adapted information access in a hypermedia in...

“…In more general terms, in addition to the basic presentation, some category of users can get some additional information which is specially prepared for this category of users and will not be shown to users of other categories. This method is used in MetaDoc (Boyle & Encarnacion, 1994), KN-AHS , ITEM/IP (Brusilovsky, 1992b), EPIAIM (de Rosis et al, 1993), and Anatom-Tutor (Beaumont, 1994). A goal-based variant of this method is to hide from the user some parts of information about a particular concept which are not relevant to the current user's goal .…”

“…At present, content adaptation is used in three classic hypermedia application areas: on-line information systems -Hypadapter , MetaDoc (Boyle & Encarnacion, 1994), KN-AHS , and PUSH , on-line help systems -Lisp-Critic , EPIAIM (de Rosis et al, 1993), WING-MIT (Kim, 1995), and ORIMUHS (Encarnação, 1995b), and educational hypermedia -Anatom-Tutor (Beaumont, 1994), ITEM/IP (Brusilovsky, 1992b), C-book , and SYPROS (Gonschorek & Herzog, 1995) (Table II).…”

“…Most part of the early works on adaptive hypermedia was centered around adaptive text presentation (Beaumont, 1994;Böcker et al, 1990;Boyle & Encarnacion, 1994;Brusilovsky, 1992b;de Rosis et al, 1993;Fischer et al, 1990). This direction of research was influenced by the research on adaptive explanation and adaptive presentation in intelligent systems (Moore & Swartout, 1989;Paris, 1988;Zukerman & McConachy, 1993).…”

“…Note that not all known systems which are named or referred to as adaptive hypermedia satisfy our definition. Some of them are not full-fledged hypermedia systems (Brusilovsky, 1992b;Yetim, 1993;André & Rist, 1996); some of them are not really adaptive, but rather adaptable (Waterworth, 1996) (this distinction will be made clearer later). There are also some projects which suggest interesting relevant ideas but have not yet reached the implementation stage (Tomek, Maurer & Nassar, 1993;Zyryanov, 1996).…”

Adaptive hypermedia is a new direction of research within the area of adaptive and user model-based interfaces. Adaptive hypermedia (AH) systems build a model of the individual user and apply it for adaptation to that user, for example, to adapt the content of a hypermedia page to the user's knowledge and goals, or to suggest the most relevant links to follow. AH systems are used now in several application areas where the hyperspace is reasonably large and where a hypermedia application is expected to be used by individuals with different goals, knowledge and backgrounds. This paper is a review of existing work on adaptive hypermedia. The paper is centered around a set of identified methods and techniques of AH. It introduces several dimensions of classification of AH systems, methods and techniques and describes the most important of them.

Hypermedia: Openness, Structural Awareness, and Adaptivity

This paper introduces an adaptive hypermedia system that provides a means for information providers to direct their users through hyperspace. With our system, the information providers are able to easily direct users to their own personalized navigation paths. Destination options are determined by hiding links and by applying rules so that the users are offered the best paths for them. In order to reduce the information providers' efforts in creating navigation rules, we simplified the format of these rules and offer an authoring tool that verifies the navigation rules and reports any errors if they exist. This tool not only allows the information providers to easily write navigation rules but also guarantees the adequacy of the navigation path.
