Adaptive On-Line Information System
Résumé
SWAN project (Adaptive and Navigating Web Server) aims to design adaptive web servers for on-line multimedia information systems about nautical publications. It is a joined project between the IASC laboratory and Atlantide - a private company. The project is funded by the west region council and supported by the French naval hydrographic and oceanographic service. In on-line information systems, users used to only access a fragment of information space according to their current goal. User’s goals can provide navigation support. In our framework, user
modelling is based on stereotypes and more precisely on prototypical user’s tasks and on user’s class. It also uses a domain model, an individual model and a maritime navigation context. The content and presentation adaptation is achieved by the sailor’s class. The task model is used to design navigation processes and to define views of hyperspace. Some tasks determine the relevant domain concepts available in a particular
geographical area, an adaptive method for them and a way to compute the hyperspace views. The system architecture is based on the one hand a WebObjects server to manage user’s recognition and web browser communication and on the other hand a knowledge based system managing the adaptation by means of a user’s model.
