Abstract

The registration device according to the embodiment includes an acquisition unit, a generation unit, a temporary registration unit, a calculation unit, a determination unit, and a registration unit. The acquisition unit acquires log data regarding a fault related to a faulty device in which a fault has been estimated to have occurred and a peripheral device installed around the faulty device. The generation unit generates a group including similar event logs issued at a certain frequency or more from the log data. When an event log in a group including an event log corresponding to training data for solving a fault corresponds to operation data related to an operation of a certain device in the group, the temporary registration unit registers the operation data as temporary training data.

First claim

The invention claimed is:

1. A registration device comprising:
an acquisition unit, comprising one or more processors, configured to acquire log data regarding a fault related to a faulty device in which the fault has been estimated to have occurred and a peripheral device installed around the faulty device;
a generation unit, comprising one or more processors, configured to generate one or more groups including similar event logs issued at a certain frequency or more from the log data;
a temporary registration unit, comprising one or more processors, configured to register operation data as temporary training data when one or more event logs in a group including an event log corresponding to training data for solving the fault correspond to the operation data related to an operation of a certain device in the group;
a calculation unit, comprising one or more processors, configured to calculate a certainty factor for each countermeasure against the fault of the faulty device based on whether there is temporary training data related to the faulty device or the peripheral device;
a determination unit, comprising one or more processors, configured to determine whether the certainty factor is equal to or greater than a threshold; and
a registration unit, comprising one or more processors, configured to register the temporary training data of which the certainty factor is equal to or greater than the threshold as the training data.

2. The registration device according to claim 1 , wherein the generation unit is configured to generate the group by executing a process by clustering for grouping similar event logs based on an occurrence frequency of event logs generated by the faulty device and the peripheral device.

3. The registration device according to claim 1 , wherein the determination unit is configured to determine whether the certainty factor of the faulty device is equal to or greater than the threshold, and determine whether the certainty factor of the peripheral device is equal to or greater the threshold when the certainty factor of the faulty device is less than the threshold.

4. The registration device according to claim 1 ,
wherein the registration unit is configured to register temporary training data corresponding to the certainty factor as training data when the certainty factor of the faulty device is equal to or greater than the threshold, and
the determination unit is configured not to determine the certainty factor of the peripheral device when the certainty factor of the faulty device is equal to or greater than the threshold.

5. The registration device according to claim 1 , wherein the generation unit is configured to generate the group using, as the log data, data including the training data including at least any one of information regarding the fault, countermeasure information of the fault, or recovery information of the fault, and the operation data including at least one of information regarding a fault of the certain device or information regarding a content related to the fault.

6. The registration device according to claim 1 , further comprising:
a reception unit, comprising one or more processors, configured to receive fault information regarding the faulty device in which the fault has been estimated to have occurred and the peripheral device installed around the faulty device,
wherein the acquisition unit is configured to acquire the log data based on the fault information.

7. A registration method comprising:
acquiring, by an acquisition unit, log data regarding a fault related to a faulty device in which the fault has been estimated to have occurred and a peripheral device installed around the faulty device;
generating, by a generation unit, one or more groups including similar event logs issued at a certain frequency or more from the log data;
registering, by a temporary registration unit, operation data as temporary training data when one or more event logs in a group including an event log corresponding to training data for solving the fault correspond to the operation data related to an operation of a certain device in the group;
calculating, by a calculation unit, a certainty factor for each countermeasure against the fault of the faulty device based on whether there is temporary training data related to the faulty device or the peripheral device;
determining, by a determination unit, whether the certainty factor is equal to or greater than a threshold; and
registering, by a registration unit, the temporary training data of which the certainty factor is equal to or greater than the threshold as the training data.

8. A non-transitory computer readable medium storing a program, wherein execution of the program causes a computer to function as each unit of the registration device according to claim 1 .
