1. A business process monitoring system to ensure business processes are followed, comprising: one or more sensors for capturing sensory data; a data storage device for storing the sensory data from the one or more sensors; one or more processors, operatively coupled to the one or more sensors; and one or more memories, operatively coupled to the one or more processors, the one or more memories comprising program code which when executed causes the one or more processors to: capture sensory data from the one or more sensors; process the sensory data from the one or more sensors to detect primitive events in the sensory data; correlate two or more primitive events, weighted by attribute data representing information about the sensors used to sense the primitive events, to determine one or more correlated events; and perform one or more actions to ensure business processes are followed based on the correlation performed in the correlating step.
