This paper introduces an adaptable hypermedia approach applied to adaptive link annotation techniques. The combination of such direct manipulation with automated link annotation affords greater user control over page adaptation. In turn, this direct control better supports user focus in information discovery tasks. Unlike adaptive-only systems, our approach lets users both define multiple topics of interest and then manipulate how these topics` associated links are presented in a page. We discuss how the approach can be applied both to pages viewed as well as to the user`s history list, thereby relieving users from the task of either adding to or organizing bookmarks. We describe the prototype developed to support these manipulations, as well as the adaptive architecture developed to support these controls.

26 AHA! meets Auld Linky : Integrating Designed and Free-form Hypertext Systems David Millard, Koen O. Aben, Hugh Davis, Paul De Bra, Mark Weal

Adaptive Hypermedia, Open Hypermedia, Hypertext Theory, Fundamental Open Hypermedia Model (FOHM)

In this paper we present our efforts to integrate two adaptive hypermedia systems that take very different approaches. The Adaptive Hypermedia Architecture (AHA!) aims to establish a consistently organized, strictly designed form of hypertext while Auld Linky takes an open and potentially sculptural approach, producing more freeform, less deterministic hypertexts. We describe the difficulties in reconciling the two approaches. This leads us to draw a number of conclusions about the benefits and disadvantages of both and the concessions that are required to combine them successfully.

27 “Pluggable” user models for adaptive hypermedia in education M.R.Zakaria, A.Moore, C.D.Stewart, T.J. Brailsford

Short paper: Adaptive Hypermedia

Most adaptive hypermedia systems used in education implement a single user model – inevitably originally designed for a specific set of circumstances. In this paper we describe an architecture that makes use of XML pipelines to facilitates the implementation of different user models

28 Is Simple Sequencing Simple Adaptive Hypermedia? Nor Aniza Abdullah, Hugh Davis

Short paper: Adaptive Hypermedia, Learning Objects, Simple Sequencing

In this paper, we explore the differences between the Adaptive Hypermedia and IMS Simple Sequencing approaches. Both approaches provide learning material tailored for the learner’s current context. Understanding the difference between the approaches enables us to identify the best features of each, and thus to identify research agendas for improvement of adaptive hypermedia and of Web-based Learning Management Systems.
