We define a new kind of stream cube, called geo-trend stream cube, which uses trends to aggregate a numeric measure which is streamed by a sensor network and is organized around space and time dimensions. We specify space-time roll-up and drill-down to explore trends at coarse grained and inner grained hierarchical view.

Abstract
We define a new kind of stream cube, called geo-trend stream cube, which uses trends to aggregate a numeric measure which is streamed by a sensor network and is organized around space and time dimensions. We specify space-time roll-up and drill-down to explore trends at coarse grained and inner grained hierarchical view.File in questo prodotto:
