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.
