Session 4: (Wednesday pm) Adaptive Hypermedia (1)
9 Integrating User Operations in Multichannel Hypermedia Franca Garzotto, Vito Perrone

Short paper: Adaptive Hypermedia, Hypertext Structure, conceptual modelling, multi-channel, services on the Web, Web operations, context, UML, OCL

Web Applications are progressively becoming multi-channel and cross-channel. The “same” service should be made available in different delivery environments and devices. A user may invoke a service on one device, suspend it, and complete its execution in another one. In this paper we provide the reader with the main concepts and innovative aspects of MC2 a design framework for specifying Multi/Cross Channel web application services. MC2 adopts an high-level, end user perspective and exploits the notion of context, to characterize who, where and how an operation can be invoked.

10 Pocket News: News Contents Adaptation for Mobile User Youn-Sik Hong, In-Sook Park, Jeong-Taek Ryu, Hye-Sun Hur

Short paper: Adaptive Hypermedia, Evaluation, Linking

We have presented a system called Pocket News that transforms web contents in the internet automatically and directly to the contents to be adapted for a mobile terminal, especially PDA. It is adequate for frequently changed web sites, like as news contents. We have also proposed a page splitting technique to navigate mobile pages with button controls instead of conventional scroll up/down controls. The proposed system also produces mHTML page for mobile phone which supports the Mobile Explorer.

11 AHA! The Adaptive Hypermedia Architecture Paul De Bra, Ad Aerts, Bart Berden, Barend de Lange, Brendan Rousseau, Tomi Santic, David Smits, Natalia Stash

Technical Briefing: Adaptive hypermedia, adaptive presentation, adaptive navigation support, authoring support

AHA!, the Adaptive Hypermedia Architecture, was originally developed to support an on-line course with some user guidance through conditional (extra) explanations and conditional link hiding. This paper describes the many extensions and tools that have turned AHA! into a versatile adaptive hypermedia platform. It also shows how AHA! can be used to add different adaptive features to applications such as on-line courses, museum sites, encyclopedia, etc. The architecture of AHA! is heavily inspired by the AHAM reference model
