INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND RECORDING MEDIUM

摘要

The present invention improves the accuracy of a risk defined for an abnormality that occurs in a system. A risk determination device 100 includes a classification unit 114 and a determination unit 115. The classification unit 114 classifies abnormal patterns 133, representing the relationship between metrics at a time when an abnormality is detected in a system, into groups 134 on the basis of similarity between the abnormal patterns. The determination unit 115 determines the likelihood of an abnormality pertaining to the groups 134 on the basis of the number of abnormal patterns 133 classified into each of the groups 134.
