Document Type and Number:
Japanese Patent JP5433765
Kind Code:
B1
Abstract:
PROBLEM TO BE SOLVED: To provide a hierarchical structure modification processing device which prevents the significant increase of the number of cases in a hierarchy as an upgrade destination and prevents a node having a large number of accesses from being taken as a downgrade object when operating a hierarchical structure.SOLUTION: A hierarchical structure modification processing device includes: storage means in which hierarchical structure data storing therein nodes of a hierarchical structure and classification result data of a plurality of nodes are stored; upgrade candidate extraction means which extracts a set of nodes as upgrade candidates which are to be upgraded from current positions to higher hierarchies under a prescribed condition; and removal means which calculates the number of cases in a hierarchy to which a node as an upgrade candidate is to be upgraded, and removes this node from the set of nodes if the number of cases is equal to or larger than a preliminarily determined threshold.
