Please help me predict the CPC LABEL for this patentPATENT ABSTRACT: The present invention is directed to a system that includes a semantic reasoning engine that is configured to convert radar track data into a directed graph representation (DGR) of the predetermined surveillance region and iteratively combine the DGRs to create a weighted directed graph (WDG) aligned and superimposed with the digital map data. The WDG includes first WDG elements corresponding to moving objects detected by a radar system. The WDG is compared to historical data to obtain a surveillance detection parameter. An alarm message is generated if the surveillance detection parameter deviates from the historical data by a predetermined amount. An output device is coupled to the semantic reasoning engine and is configured to provide a representation of the digital map data, the WDG and the at least one alarm message.
