Finding the optimal selection of an OWL reasoner and service interface for a specific ontology-based application is challenging. Over time it has become more and more difficult to match application requirements with service offerings from available reasoning engines, in particular with recent optimizations for certain reasoning services and new reasoning(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)
—Network emulation using real sensor node hardware is used to increase the accuracy of pure network simulations. Coupling OMNeT++ with network emulation platforms and tools introduces new application possibilities for both sides. This work-in-progress report covers our experiences of using OMNeT++ as a test driver for RoSeNet, a network emulation and test(More)
