Abstract: The present invention provides an information processing system for more appropriately classifying elements that constitute an information processing device or the like. This information processing system is provided with: a means that, on the basis of information indicating the relationship between a plurality of elements that constitute a system, acquires, for first elements to be classified, a set of second elements capable of arriving at the first elements via a relationship of arbitrary numbers; and a means that, on the basis of the set corresponding to the first elements, classifies each of the first elements in any of a plurality of roles.

Abstract: Disclosed are an event estimation device, etc., which are capable of estimating with high precision whether a communication is singular. Provided is an event estimation device (101), comprising: a model creation unit (102) which creates a model which, on the basis of a frequency with which a communication is executed, computes that a degree of singularity which represents the extent to which the communication is singular is high if the frequency is low, and computes that the degree of singularity is low if the frequency is high; and an estimation unit (103) which computes the degree of singularity by applying the model to the frequency relating to a given communication, and if the computed degree of singularity satisfies a standard, estimates that the given communication is singular, and if the computed degree of singularity does not satisfy the standard, estimates that the given communication is not singular.

Abstract: Information regarding moving bodies (00) that are in danger of colliding is collected at an appropriate frequency in accordance with the degree of danger. This information-collecting device has a risk calculation means and a transmission-interval determination means. The risk calculation means receives, from a plurality of moving bodies, state information that includes locations and velocities and is transmitted at provided time intervals. The risk calculation means also computes the distance between and relative velocities of two moving bodies. The transmission-interval determination means computes an interval such that the higher the relative velocities of two moving bodies are relative to the distance therebetween, the shorter the interval is, and provides the computed interval to said moving bodies.

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.
