Abstract: An information processing apparatus includes: a reach-extent extraction unit configured to extract, with use of a relationship graph representing relationships between a plurality of elements included in a system and location information that indicates, on the relationship graph, a plurality of locations in the system where anomalies have been detected, paths in the relationship graph as being reach extents, the path including a set of the elements that are directly or indirectly related to each of the plurality of locations as a source; and a shared-extent extraction unit configured to extract an influence process of an anomaly by extracting an extent that is shared in at least a prescribed number of paths among paths in the relationship graph that have been extracted as the reach extents.

Abstract: The present invention provides an information processing device that improves the detectability of system errors. This information processing device includes: a means that generates a state graph based on relationship change information indicating a change in the relationship between a plurality of elements included in a system, the state graph having the elements as the vertices thereof and the relationship between the elements as the sides thereof; a means that generates a normal model having the state graph as a set of conditions to be fulfilled during normal system operation, based on the relationship change information; and a means that detects system errors and outputs error information indicating detected errors, based on the state graph and the normal model.
