6. An information processing method comprising:
extracting neighboring nodes in two or more different extraction ranges for each node constituting input data of a graph structure;
calculating an anomaly score representing a degree of anomaly of the node for each extraction range based on a representation of a combination of the node and the neighboring nodes;
selecting a maximum anomaly score among the anomaly scores recorded in the storage;
determining an anomaly node in the input data of the graph structure based on the selected maximum anomaly score; and
outputting information of the anomaly node.
