Claim 0:
1. An apparatus for assisting maintenance work comprising:
hardware configured to:
acquire a data set including a combination of device information of a target device and operation information of the target device, or a data set including a combination of the device information of the target device and event information indicating an event for the target device;
acquire work content information indicating a content of maintenance work, for the target device, performed through a maintenance operator, the work content information indicating a replaced or repaired part, or a new part after replacement; and
perform learning based on the acquired data set, the data set being associated with the replaced or repaired part, or the new part after replacement that is indicated by the acquired work content information, wherein the learning includes:
processing an input of the data set or a portion of the data set, in accordance with model parameters of a machine learning model;
determining work content information applied to the input; and
updating the model parameters of the machine learning model based on the determined work content information,

wherein the hardware is configured to:
newly acquire a data set including a combination of device information of the target device and operation information of the target device, or a data set including a combination of the device information of the target device and event information indicating an event for the target device, and
infer, based on a result of the learning, a part to be replaced or repaired, or a new part after replacement, with respect to the target device, from the newly acquired data set,

wherein the work content information includes an anomaly location and a confidence level associated with the anomaly location, and
wherein the hardware is configured to perform the learning upon occurrence of a condition in which the confidence level in the work content information is higher than a threshold.
