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...

This paper describes the use of adaptation patterns in the task of formulating standards for adaptive educational hypermedia (AEH) systems that is currently under investigation by the EU ADAPT project. Within this project, design dimensions for high granularity patterns have been established. In this paper we focus on detailing lower granularity adaptive patterns based upon learning styles. Sev...

In this paper, we show how existing adaptive educational hypermedia systems can be enhanced by policies. In traditional systems, the adaptation is based on predefined user and domain models and fairly restricted adaptation rules. Policies allow for sophisticated and flexible adaptation rules, provided by multiple stakeholders. We present the benefits and feasibility of the approach with AHA! as...

An increasing number of Website developers try to provide some kind of “personalization”. In this paper we show how the designers (called “authors” in this paper) can build their adaptive presentations using the AHA! system (for Adaptive Hypermedia Architecture). Most existing Adaptive Hypermedia Systems are special-purpose, aimed at one specific application or application area (mostly educatio...

This paper presents a quantitative study on the use of Topolor a prototype that introduces Web 2.0 tools and Facebook-like appearance into an adaptive educational hypermedia system. We present the system design and its evaluation using system usability scale questionnaire and learning behavior data analysis. The results indicate high level of student satisfaction with the learning experience an...

This paper presents results from a post-analysis of three previously reported experimental studies on adaptive educational hypermedia. In this new analysis, interaction effects of the post-hoc variable “previous knowledge of learners” and the adaptive treatments were found. The interaction effects have an impact on learners’ scores in knowledge tests, the time learners needed to browse adaptive...

Adaptive learning technologies have been demonstrating effective by many types of adaptive educational systems (e.g., intelligent tutoring systems, adaptive hypermedia systems, adaptive assessment systems). NMC Horizon Report 2015 predicts that this kind of learning technologies would be deployed widely in higher education in four to five years. Recently, there is a trend of shifting the measur...

We present Adaptive Bayes, an adaptive incremental version of Naïve Bayes, to model a prediction task based on learning styles in the context of an Adaptive Hypermedia Educational System. Since the student’s preferences can change over time, this task is related with a problem known as concept drift in the machine learning community. For this class of problems an adaptive predictive model, able...

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...
