Abstract(in English) It is important to identify the suspected failure point quickly in order to realize the early restoration in the failure response work of a large-scale network. So far, we have proposed a technique to automatically create If-then rules to estimate the failure point by using failure response history and event information (Trap information and alarms) of monitoring system as training data. Our technique realizes to specify the failure point independently of skill and know-how of the maintenance person. However, existing methods focus only on events that occur in the device, so if there are rules generated for failures that occur in fewer types of events than other failures, multiple failures may be detected in addition to true failure, and the failure type may not be identified as one. Therefore, the failure may not be identified, and further isolation may be required. In this paper, by considering events that did not occur in comparison with other failure classification, we propose an automatic generation technique of If-then rules with negative conditions for events that did not occur, and show its superiority and applicability to actual operation.
