An information selection device and the like capable of promptly acquiring information regarding a phenomenon of interest are disclosed. The information selection device 401 may have an influence on the abnormal process executed in the target system among the log information indicating that the process is executed for the process target in the target system. A target information specifying unit 402 that specifies target log information including a processing target, calculates the frequency of the target log information for each combination of the process and the process target, and the target log information is abnormal based on the calculated frequency. A calculation unit 403 that calculates an abnormality degree indicating a certain degree and a selection unit 404 that selects, from the target log information, relevant log information that satisfies the criterion for determining abnormal log information.
