Towards a framework for distributed user modelling for ubiquitous computing

This paper introduces a framework for distributed user modelling in ubiquitous computing. Regarding the requirements in ubiquitous computing, communication details are not fixed per se or even unknown during the system specification phase. Hiding the technology within specialized components allows for unique migration of information between the components and releases system developers from considering specific properties and protocols. Supporting efficient development of applications, the distributed components are able to react both to their environment and to messages received from neighbouring components.
