Abstract: A placement device may reduce the cost for placing an object when a placement destination, in which an object is placed, changes due to the addition of a placement destination. A placement device may: determine, upon receiving object information assigned to an object, as the placement destination in which the object is placed from among one or more placement destinations each having an assigned set value, the placement destination added most recently and assigned a set value larger than a characteristic value derived uniquely based on the object information; and change, when a placement destination is added, based on an available capacity representing the amount of objects that can be newly placed in the placement destinations, the set value assigned to at least one of the placement destinations such that the determined placement destination does not change to a placement destination other than the placement destination added last.

Abstract: An information processing device includes acquisition means for acquiring a plurality of tree structure data in which information groups are represented by tree structures and merge means for generating merged tree structure data merging the plurality of tree structure data. The merge means merges, for information satisfying a condition indicating that a certain distance from other information in the tree structure data is maintained, a subtree at a level below the information in the tree structure data, into the merged tree structure data, wherein the information satisfying the condition is included in a node selected from the plurality of tree structure data; and reorganizing for information satisfying a condition indicating that the distance between pieces of information is short, a merged subtree by merging subtrees below the information in the tree structure data into the information.

Abstract: An information processing apparatus according to this invention, upon acquiring target data, computes an evaluation value between the target data and each piece of representative data. The information processing apparatus determines, for each piece of representative data, whether the evaluation value computed between the representative data and the target data satisfies a predetermined relationship with a threshold related to the representative data. When it is determined that the evaluation value computed between the target data and certain representative data satisfies the predetermined relationship with the threshold related to the representative data, the information processing apparatus stores the target data in a storage area related to the representative data. The information processing apparatus updates the threshold related to each piece of representative data. The update of the threshold related to certain representative data is performed based on the total size or the total count of pieces of data stored in a storage area related to the representative data, or the free space of the storage area related to the representative data.

Abstract: An information management device includes: an identification unit that identifies, when any piece of information among plural pieces of information managed by constructing a structural model representing a mutual relevance is deleted from the structural model, information-to-be-modified having the relevance with information deleted (deleted information) meeting a predetermined condition in the structural model before deletion of the deleted information, among the plural pieces of managed information; and a modification unit that modifies, based on a criterion relating to the relevance and a configuration of the structural model before deletion of the deleted information, a configuration of the structural model relating to the identified information-to-be-modified, thereby efficiently performing processing of reconstructing a structural model representing a mutual relevance when any piece among plural pieces of information managed by constructing the structural model is deleted.
