    Abstract: Provided is an information processing device which is capable of suppressing a deterioration in accuracy of detecting an anomaly and accuracy of analyzing the anomaly, while suppressing an increase in an amount of data to be stored. The information processing system includes anomaly detection unit that collects event data indicating a predetermined event detected in a process of a device to be monitored, determines whether a predetermined index value related to the event exceeds a preset first threshold, and instructs enhanced monitoring of the device to be monitored and the process related to the event when the index value exceeds the first threshold, and collection instruction unit that determines an additional event being an event to be additionally monitored when the enhanced monitoring is instructed, and instructs the device to be monitored, which is subjected to the enhanced monitoring, to monitor the determined additional event.

    Abstract: Provided is an air traffic control assistance system whereby it is possible to display the reliability of an avoidance recommendation over time in a manner which is easily understood by an air traffic controller. For each combination of link information of an aircraft of interest and link information of an aircraft in the vicinity thereof, a graphic identification unit identifies a graphic which represents a prescribed range which is defined by the aircraft in the vicinity thereof, in a plane which includes a three-dimensional vector which is represented by the link information of the aircraft of interest and which is perpendicular to the x-y plane. When transforming a two-dimensional vector in an x-y plane from one fix of the aircraft of interest to the next fix to align in order along the x-axis, a transform matrix computation unit computes, for each two-dimensional vector, a transform matrix which represents a transform from a plane which contains the two-dimensional vector and is perpendicular to the x-y plane to a plane which is defined by the x-axis and a time axis. A display processing unit transforms the graphic, and displays a line which joins the fix and a point which is determined by the time whereat the aircraft of interest transects the fix, and the transformed graphic.

    Abstract: The purpose of the present invention is to provide a technology which assists a verifying party in ascertaining an anomaly in an event of which notification has been made. Provided is an assistance device, comprising: an acquisition unit which acquires as an associated event, from among events which take place among a plurality of elements, and with respect to elements which have been associated with an event which has been detected as an anomalous event, an event other than the anomalous event which has been associated with the elements; and a generating unit which, on the basis of the anomalous event and the associated event, generates a relational graph in which the elements are vertices, the relations among the elements are edges, the anomalous event and the associated event are respectively represented, and the associated event is displayed in a display screen in a different manner from the manner in which the anomalous event is displayed.
