Abstract: An air traffic control support system for more quickly grasping a flight plan in air traffic control is provided. An air traffic control support system 3 includes a learning unit 100 and a prediction unit 200. The learning unit 100 generates a prediction model, based on learning data including a past flight plan and information that affected formulation of the past flight plan. The prediction unit 200 predicts a flight plan, based on information that affects formulation of the flight plan and a prediction model.

Abstract: An information determination apparatus includes a first storage unit configured to store stream data pieces obtained in time sequence; a first determining unit configured to determine whether the number of stream data pieces stored in the first storage unit is at least equal to a predetermined value; and a second determining unit configured to determine, when the number of the stream data pieces stored in the first storage unit is equal to or greater than the predetermined value, whether an individual can be identified based on a dataset composed of a plurality of the stream data pieces stored in the first storage unit, and output the dataset used for the determination and the determination result.

Abstract: Provided is a learning model generation system capable of preventing a decrease in prediction accuracy in a case where the trend of an actual value of a prediction target has changed. The learning model generation means 71 generates a learning model using, as learning data, time series data in which a value of each explanatory variable used in prediction of a prediction target is associated with an actual value of the prediction target. The prediction means 72 calculates a predicted value of the prediction target using the learning model once the value of each explanatory variable is given. The change point determination means 73 determines a change point which is a point in time when a trend of the actual value of the prediction target changed.

Abstract: Provided are a rule distribution apparatus, an event processing system, a rule distribution method, and a rule distribution program, with which it is possible to prevent bottlenecking of specific resources in a network, thereby maintaining high service quality.

Abstract: The number of dispatch rules set to each dispatcher is reduced in an event processing system. An event processing system includes a distribution controller 100 and a plurality of dispatchers 300. To each of the plurality of dispatchers 300, dispatching target attribute information, that is attribute information included in an event 601 that is a dispatching target for the dispatchers 300, has been assigned. The distribution controller 100 sets a dispatch rule 604 including a dispatch condition indicating one or more conditions of attribute information included in an event 601 and a destination of an event 601 that satisfies the dispatch condition to the dispatchers 300, to which the dispatching target attribute information matching any one of the conditions of attribute information included in the dispatch condition of the dispatch rule 604 has been assigned, among the plurality of dispatchers 300.

Abstract: Provided is a pattern matching device capable of generating an event pattern matching tree optimal for efficiently performing pattern matching assessment. The pattern matching device is provided with an event pattern table holding unit for holding an event pattern including a partial event pattern comprising a first attribute name and an attribute value; a first matching ratio measurement unit for measuring a matching ratio corresponding to the first attribute name on the basis of an event including attributes comprising a second attribute name and an attribute value and the event pattern; and an event pattern matching tree generation unit for generating an event pattern matching tree which has arranged on an upper level an attribute value matching assessment instance including the first attribute name which has the low corresponding matching ratio on the basis of the event pattern and the matching ratio.

Abstract: There has been a problem that it is impossible to ensure the ability to acquire RFID tag state information and at the same time reduce the power consumption necessary therefore. Provided is a tag reader including a read means, which detects the loss of communication with a tag during communication with the tag, and a control means, which counts the number of times communication with the tag is lost on the basis of the losses detected by the read means and disables execution of a communication process with the tag when the number of losses has reached a predetermined threshold value.

Abstract: An information terminal that reduces the effort of presence input is provided. The information terminal is connected via a network to a server for disclosing a presence that is a present state of each user or each object, and includes: a display unit for displaying a presence input screen that is a screen for inputting the presence; a storage unit storing a terminal identifier that differs from one user terminal to another and information on the presence input screen; and a control unit that causes the presence input screen to be displayed on the display unit upon receiving a presence input request signal that is a signal for requesting input of the presence from another information terminal via the network, and when the presence is inputted via an operating unit, transmits the terminal identifier together with the presence to the server.
