IDENTIFICATION DEVICE, IDENTIFICATION METHOD, AND IDENTIFICATION PROGRAM

摘要

An objective of the present device is to effect a reduction in computational volume in deriving a correspondence among a plurality of instances of data which are observed in isolation. An identification device: acquires a request of a different type from a request to be investigated which is transmitted from a first device to a second device and whereupon a response is transmitted from the second device to the first device in a processing period for the request to be investigated and each request of a group of requests of a similar type; generates combinations with the request of the different type; deletes the combinations which match the request of the different type among given combinations; acquires a second request after the deletion from a second request group which is processed with the second device, during the processing period; computes a correspondence value after the deletion with the acquired second request, and outputs the result of the computation.
