To provide an abnormality determination device that enables selection of learning data taking into account influence of nearby nodes for creating an abnormality detection model for a network by machine learning.SOLUTION: An abnormality determination device 125 which is included in a first node being monitored in a network includes a processor configured to: acquire log information, which includes a time of day and information about the state of the first node at the time of day indicated by sensor data or control data at the first node; execute a first abnormality determination related to the occurrence of an abnormality in the first node at the time of day; execute a second abnormality determination related to the occurrence of an abnormality in a second node at the time of day, on the basis of second node information acquired from the second node and related to an abnormality in the second node, where the second node is in the vicinity of the first node and is another monitoring subject; and, when an abnormality has occurred in the second node, append abnormality information indicating that the abnormality has occurred in the second node to the log information, and transmit the log information to at least some nodes on the network.SELECTED DRAWING: Figure 3

    【課題】ネットワーク用の異常検知モデルを機械学習で作成するために、周辺ノードの影響を考慮に入れた学習データの選定を可能にする異常判定装置を提供する。【解決手段】ネットワーク上の監視対象である第一ノードに含まれる異常判定装置125は、時刻と、第一ノード上のセンサデータ又は制御データが示す、当該時刻における第一ノードの状態情報とを含むログ情報を取得し、当該時刻における第一ノード上の異常の発生に関する第一異常判定を実行し、第一ノードの周辺にあって他の監視対象である第二ノードから取得した第二ノードの異常に関する第二ノード情報に基づいて、当該時刻における第二ノード上の異常の発生に関する第二異常判定を実行し、第二ノード上で異常が発生していた場合、ログ情報に第二ノード上での異常の発生を示す異常情報を付加してネットワーク上の少なくとも一部のノードに送信するプロセッサを含む。【選択図】図3
