<P>PROBLEM TO BE SOLVED: To prevent a node that is only infrequently connected to other nodes from tightening in link to any other node. <P>SOLUTION: An information analyzing device 10 acquires linking information indicating directed links set between a plurality of nodes, updates the acquired linking information by adding to a plurality of nodes having directed links, virtual nodes that are connected from individual ones of a plurality of nodes and connected to individual ones of a plurality of nodes, selects nodes whose number of connections to other nodes are less than a first value out of a plurality of nodes, sets links to the virtual nodes until the numbers of connections of the selected nodes reach the first value, and thereby further updates the linking information. The information analyzing device 10 makes bidirectional the links indicated by the updated linking information set in each of the plurality of nodes and the virtual nodes to further update the linking information, and calculates the weight of each link indicated by the further updated linking information. <P>COPYRIGHT: (C)2012,JPO&INPIT |
