We consider situation-aware mobile services as applications that could benefit considerably from advances in stream reasoning technology. Our initial realization of a situation-aware mobile service infrastructure combines streams of context information gained from mobile sensors and various Web resources and applies expressive reasoning. With the(More)
In this paper we describe our ongoing work and first prototypes in the area of advertising on public screens in combination with mobile devices. We are especially interested in exploiting personal user profiles and explicit input from users in order to provide appropriate advertisement content. Static displays such as paper posters as well as dynamic(More)
We present IYOUIT, a prototype service to pioneer a context-aware mobile digital lifestyle and its reflection on the Web. The application is based on a distributed infrastructure that incorporates Semantic Web technologies in several places to derive qualitative interpretations of a user's digital traces in the real world. Networked components map(More)
This paper explores the possibilities and core technologies of the ongoing development towards the Semantic Web for desktop application enhancement. It demonstrates how an ontology-based software can provide refined support for personal information organization. The Web Ontology Language and reasoning mechanisms based on Description Logics (DL) are analyzed(More)
IYOUIT is a prototype mobile service to pioneer a context-aware digital lifestyle and its reflection on the Web. The service is made freely available and leverages Semantic Web technology to implement smart application features. We intend to not only present and demonstrate IYOUIT at ISWC'08 but also to provide it to conference attendees, based on their(More)
We have implemented and evaluated IYOUIT, a context-aware application for the mobile phone that promotes a digital lifestyle, sharing, and life-logging approach for people on the go. The service incorporates context management technology to abstract data about and around the user into meaningful interpretations of the user's digital trace in the real world.(More)
