Kurzfassung
We present CAREY, an alert system notification for regions
in state of emergency. CAREY implements the mediator-wrapper archi-
tecture on top of the Geospatial Web to visualize risky regions in terms of
their weather conditions. We illustrate the formalization of the problem
of detecting risky regions as a two-fold problem that relies on annota-
tions of sensor data with the ontology of Observations and Measurements
(O&M) to enhance state-of-the-art data mining and ranking techniques.
First, sensor observations are clustered according to their Geospatial in-
formation then, proximate regions are clustered into micro-climate areas
in terms of the similarity of their weather conditions. Finally, Top-k
Skyline techniques are used to identify the top-k areas that best meet
criteria of risk among the areas that are incomparable with respect to
this condition. We demonstrate the capabilities of CAREY.
