9. The system of claim 8 , wherein said model builder performs said feature extraction for each deployed application to obtain application specific feature vectors of motion trajectory, thereby transforming a single set of motion trajectory data into application specific behavior assessments for each application context supporting multi-perspective behavior assessment of a moving object.
8. The system of claim 1 , wherein said model builder performs feature extraction for a trajectory associated with a deployed application by: (a) obtaining target specific score values by applying user selected intention functions to target areas specified in an application context; (b) normalizing the target specific score values by applying reference score assessment models that are continuously updated; (c) weighting each of the target specific score values by their respective criticality values, wherein the criticality values and the target areas user-defined; (d) finding an element having a maximum score value in a target-score evaluation matrix; and (e) determining an application specific semantic event by using an element-specific target area and its intention function, wherein the element-specific target area is associated with the element having the maximum score value.
