Present hypermedia systems typically do not handle well problems associated with the browsing and editing of hypermedia information structures. This is largely a result of inadequacies in the underlying model used to represent the hypermedia information. In particular, current hypermedia models typically do not make explicit the difference between data and information, nor do they consider the ...

The goal of this research is to provide hypermedia functionality to all information systems that interact with people. Hypermedia is a concept involving access to information, embodying the notions of context-sensitive navigation, annotation and tailored presentation. We present the architecture of a system-level hyperniedia engine, designed both to manage full hypermedia functionality for an i...

The next generation of hypermedia systems will undoubtedly incorporate many concepts and techniques taken from the field of artificial intelligence and knowledge-based systems, in order to add more intelligence to the basic hypertext model. In this paper, we discuss where this need for more intelligent hypermedia systems comes from, by looking at the major authoring and reading problems charact...

In this paper we present a novel approach for defining hypermedia applications as navigational views of an object-oriented hypermedia schwma. We briefly describe OOHDM (Object-Oriented Hypermedia Design Model) using an academic information system as a concrete example to illustrate each modeling construct. We further analyze the whole process of hypermedia applications building focusing mainly ...

Adaptive hypermedia is a new area of research at the crossroads of hypermedia, adaptive systems and intelligent tutoring systems. The goals of this paper are to provide a brief overview of this area and to synthesize a generalized view of the organization of existing adaptive hypermedia systems. We discuss three important questions: why do we need adaptive hypermedia (AH), where can it be usefu...

Current approaches for continuous media (CM) file systems focus on scheduling requirements for sessions consisting of single video or audio streams. This paper examines the multimedia delivery problem from the perspective of hypermedia document servers. Such hypermedia documents can be characterized as a web of nodes, each node containing a set of time-dependent CM and discrete media objects. W...

This paper discusses an approach to scripting in open hypermedia systems. The approach is based on an embedded interpreter that enables scripts to communicate with the hypermedia engine as well as external applications in an open way. The design and implementation of the scripting facilities in the Webvise open hypermedia system exemplify this approach. In Webvise, scripting is closely connecte...

This chapter focuses on the aspect of Authoring in Adaptive Hypermedia, from some of its different perspectives, including authoring for learning environments. It starts by showing the necessity of research in this area, then describes a new framework model for authoring of Adaptive Hypermedia, LAOS. Within LAOS, the adaptation model, which is the main aspect of adaptive hypermedia, is detailed...

Hypermedia extends the hypertext paradigm into multimedia. Recently, many enterprises have attempted to incorporate hypermedia functionality into their diverse range of business applications such as decision support systems, document management, software management, and team collaboration. This paper presents a methodology for designing hypermedia applications based on users’ views. In designin...
