Abstract(in English) Context awareness is believed to be a key enabler for the new network service paradigm brought by cloud computing platforms and smartphone OSs. This work focuses on the core problem of how to detect changes of context for network services. Detection of such changes can trigger timely system reconfigurations. In this paper, we propose a trigger detection mechanism based on a mixed representation model that encodes geographical and social relationships among people and other social objects by using a graph. When a significant change in the graph occurs, our mechanism detects a trigger. It accounts for the fact that a geographical relationship among objects socially connected with each other significantly changes. The main benefits of our method are that 1) it does not require building reference models in advance, and 2) it can deal with different kinds of social objects uniformly once the graph is defined. We evaluate the performance of our method by a computer simulation.
