    Abstract: An information processing apparatus acquires monitoring data. The monitoring data is data representing an event occurring in the monitoring target system. The information processing apparatus determines whether or not the event represented by the monitoring data is an event to be warned. This determination is made using the determination model. The determination model is a model for determining whether or not the event is a warning target. The information processing apparatus updates the determination model, based on the monitoring data and the result of determination on the monitoring data by using the determination model.

    Abstract: Disclosed are an information selection device and the like that make it possible to rapidly acquire information about an event of interest. An information selection device is configured to specify target log information among log information. The log information represents that a process is executed for a processing object in a target system and the target log information represents a processing object that may affect an abnormal process executed in the target system. The information selection device is configured to calculate a frequency of the target log information for each combination of the process with the processing object, calculate an abnormality degree of the target log information based on the calculated frequency and select relevant log information with having the abnormality degree satisfying a condition for determining abnormal log information among the target log information.
