Decision Support for Personalization on Mobile Devices

During the past few years mobile phones have become an ubiquitous companion. Starting as a handset to cellular networks today's mobile phones are devices capable of intelligent services itself. The IASON project aims at providing mobile users with location-aware personalized information. Motivated by the development of powerful mobile devices and the semantic web, we define a Semantic Mobile Environment. In such an environment, so-called service nodes are installed at chosen points of interest. These service nodes broadcast semantically annotated messages to nearby mobile users using bluetooth ad-hoc wireless technology. Location-awareness is given implicitly by being in the wireless range of a service node and comes free of costs just as the communication itself. A Semantic User Profile describing the users interests and disinterests is managed on her mobile device. This user profile is used to sort out unwanted messages by performing matchmaking between the semantic annotation of the messages and the user profile (see [8]). The protection of privacy requires the profile to stay on the phone and to perform all necessary reasoning on the phone.
