Co clustering device, CO clustering method and co clustering program

摘要

PROBLEM TO BE SOLVED: To provide a co-clustering device capable of performing adequate clustering.;SOLUTION: A co-clustering device includes an extended edge matrix generation part 102 which generates an extended edge matrix from link relation between an object and a property, and an exceptional object having links to all properties, a normalization part 103 which normalizes the extended edge matrix, a characteristic space conversion part 104 which converts the normalized extended edge matrix to a characteristic space, an object clustering part 105 which generates a cluster from an object arranged in the characteristic space, and a property classification part 106 which classifies properties arranged in the characteristic space such that a property which is suitable to the obtained cluster and closely corresponds to one cluster is classified into the obtained cluster, and a property which is not suitable to the obtained cluster and corresponds to a plurality of clusters is classified into the exceptional cluster.;COPYRIGHT: (C)2013,JPO&INPIT
