CAUSAL ANALYSIS DEVICE, CAUSAL ANALYSIS METHOD, AND NON-TRANSITORY COMPUTER READABLE STORAGE MEDIUM

摘要

A causal analysis device according to an embodiment includes an extractor, a counter, a calculator, and a generator. The extractor performs extraction from combination data in which an incident and one or a plurality of factors causing the incident are associated with each other in accordance with occurrence of combination data. The counter counts the number of occurrences of the incident or the number of occurrences of a combination of the plurality of factors on the basis of a combination of the incident and the factors included in the extracted combination data. The calculator calculates an index value that corresponds to the combination of the incident and the factors and changes in accordance with the number of occurrences of the combination of the incident and the factors on the basis of a result of the counting of the counter. The generator generates an image in which an image indicating the index value calculated by the calculator for each combination of the incident and the factors is associated with the combination of the incident and the factors.
