PROBLEM TO BE SOLVED: To achieve high-speed cluster processing.SOLUTION: First sorting processing is executed on target information with a first cluster technique which is different from a second cluster technique and faster than the second cluster technique. Based on the result of the first sorting processing, second sorting processing is executed with the second cluster technique. The classification of the target information is determined based on the first sorting processing result and the second sorting processing result. |
