Abstract(in English) | Bayesian network is desired as an effective approach for the decision support of the observation areas in a situational awareness (medical diagnosis, intruder surveillance and so on). In each observation area, Occurrence or non-occurrence of the events related to the target of situation awareness (disease, intruder's purpose and so on) changes with time. However, Bayesian network cannot handle the probability event that changes with time. To solve this problem, we proposed the method that introduces the time concept to Bayesian network for the decision support of the observation areas. The proposed method extends Bayesian network to estimate the temporal state (for example, inactive, active and complete) about each phase of the target scenario. Specifically, the time progression of the scenario is estimated by changing the probability value of the temporal state of each phase based on "the temporal state of the before and after phases" and "the acquisition time and the content of observation information". This estimation result would be utilized to recommend the phase of the active state as the target that should be observed preferentially. |
