DAISy Dynamic Ambient Intelligent Systems Unit

The vision of Ambient Intelligence (AmI) implies a seamless environment of computing, advanced networking technology and specific interfaces. Technology becomes embedded in everyday objects and environments such as furniture, clothes, vehicles, roads and smart materials, and people are provided with the tools and the processes that are necessary in order to achieve relaxing interactions with this environment. The AmI environment can be considered to host several Ubiquitous Computing (UbiComp) applications; a UbiComp application can be considered as a result of the dynamic, ad-hoc composition of the services offered by the AmI environment and the objects therein. Key features of such applications are context-aware operation and emergent collective functionality. To achieve these, among others, one has to deal with heterogeneity and support adaptive composition and use. To do this, we propose to employ knowledge management and decision making techniques. As a first step, we present in this paper a service ontology and the management mechanisms we have developed in order to enable AmI artifacts to apply a common world model and a set of procedures that implement the composition of service-oriented UbiComp applications.
