A method and/or system for managing a database that stores space-time context objects is provided. The system receives a query range in a multi-dimensional space. The system maps the query range into a set of fragments of a space-filling curve that fills the multi-dimensional space in all dimensions of the multi-dimensional space. The system uses each mapped fragment in the set of mapped fragments as a key to query the database for space-time context objects that are mapped to the space-filling curve. The system queries the database by identifying one or more context objects that intersect the mapped fragment at the space-filling curve.

Spatial-temporal query for cognitive IoT contexts

An embodiment of the invention may include a method, computer program product and computer system for managing mobile objects. The embodiment may receive an event detected in a geographic space by a mobile object of a plurality of mobile objects. The embodiment may determine a reliability of the event based on a reliability associated with the mobile object. The embodiment may store the event in a mobile object database based on the reliability of the even being above a reference reliability.

Management of mobile objects

At least one subsystem among the plurality of subsystems includes a managing section operable to manage individual route information for routes in a management target region of the at least one subsystem among the plurality of regions and adjacent route information for routes positioned in a partial range from a boundary of the management target region among routes in an adjacent region that is adjacent to the management target region, and an identifying section operable to identify the route on which the moving object is positioned based on the observation position, by using the individual route information and the adjacent route information managed by the at least one subsystem. Also provided is a method and computer program product.

Geographic space management

An embodiment of the invention may include a method, computer program product and computer system for managing mobile objects. The embodiment may determine, by a mobile object server, a position of a mobile object in a geographic space managed by the mobile object server. The embodiment may determine a plurality of routes based on the position of the mobile object in the geographic space. The embodiment may calculate, by the mobile object server, a plurality of route parameters for the plurality of routes, wherein the plurality of route parameters includes a passage possibility of the mobile object over each route. The embodiment may calculate a plurality of edge parameters for a plurality of edges, wherein each edge is a segment of a route, and wherein the edge parameter includes the passage possibility of the mobile object over each edge.

A system is provided that manages a geographic space including a route on which a moving object moves, including a plurality of subsystems operable to respectively manage maps of a plurality of regions obtained by dividing the geographic space, and a region manager operable to adjust loads of the subsystems by dynamically changing a boundary of at least one region among the plurality of regions. Also provided is a method and computer program product.

A system is provided that manages a geographic space including a route on which a moving object moves, including a subsystem operable to manage a map of the geographic space, and an update manager operable to change a boundary of an update block, which is a unit of an update contained in the map, according to an extent to which the update block is updated. Also provided is a method and computer program product.

To use a high-quality driving support and automatic driving system that manages a plurality of mobile objects through communication with the mobile objects to manage mobile objects that do not communicate with this system, provided is a system including a mobile object server operable to assist with movement of a plurality of mobile objects within a geographic space, wherein the mobile object server having: a monitoring section operable to monitor movement of a first mobile object that does not receive at least a portion of movement assistance and an assisting section operable to assist with movement of a second mobile object that is an assistance target, using a result obtained by monitoring the first mobile object. Also provided is a method and program product.

At least one subsystem among the plurality of subsystems includes a managing section operable to manage individual event information for events occurring in a management target region of the at least one subsystem among the plurality of regions and adjacent event information for events occurring in a partial range from a boundary of the management target region among routes in an adjacent region that is adjacent to the management target region, and an event selecting section operable to select events about which the moving object is to be informed, from the individual event information and the adjacent event information managed by the at least one subsystem. Also provided is a method and computer program product.
