Adaptive hypermedia systems are spreading widely in these last years, but each application uses its own models and techniques. What I am studying is the possibility of developing a framework for user modelling in adaptive systems and in particular of creating a library of stereotypes for representing the different dimensions of the user models.

In people’s home the amount of on-line available digital content such as video, music, or pictures is rapidly increasing. First home server products are available. Efficient selection of content will be a problem for users. We developed a flexible multimodal dialog system to overcome this. A keycomponent is the user model, which learns very fast from user behaviour. All information like key-wor...

To date, most research on user models has been viewing the models as a single homogeneous entity. In contrast, a small number of recent modular approaches to user modelling permit the separate (and possibly heterogeneous) representation and acquisition of different aspects of the model, corresponding to different, competing user interests. This modularisation increases the flexibility, portabil...

The next generation of consumer goods, including computers, will be much more sophisticated in order to cope with a less technologically literate user base. A user model is an essential component for “user friendliness”, enabling the behaviour of a system to be tailored to the needs of a particular user. In this paper, we briefly outline the problems of user modelling, especially uncertainty, u...

The increasing trend towards powerful mobile phones opens many possibilities for valuable personalised services to be available on the phone. Client-side personalisation for these services has important bene ts when connectivity to the cloud is restricted or unavailable. The user may also nd it desirable when they prefer that their user model be kept only on their phone and under their own cont...

Effective distributed user modelling in intelligent tutoring systems requires the integration of both pedagogical and domain applications. This integration is difficult, and often requires rebuilding applications for the specific elearning environment that has been deployed. This paper puts forth both an architecture and an implementation prototype for achieving this integration. It focuses on ...

This paper formally defines a web component model enabling end-user programmers to bui ld component-based r ich internet applications (RIAs) that are tailored to meet their particular needs. I t is the product of a series of previously published papers. The formal definit ion in description logic verifies that the model is consistent and subsumes currently existing models. We demonstrate experi...

In a distributed multi-agent based software environment, the traditional monolithic user model ceases to exist and is replaced by user model fragments, developed by the various software agents populating the environment. These model fragments have been developed in a variety of specific contexts to help achieve various goals. User models are thus fragmented, relativized, local, and often quite ...

In this paper a method is presented for adding user modelling to existing software systems. The method consists of seven steps that lead from initial analysis to the definition and evaluation of the elements needed for the adaptive behaviour. Further the concept of an adaptation element is introduced. Such an adaptation element can be used to determine the impact of personalisations.
