Information recommendation apparatus, information recommendation method, and information recommendation program

摘要

PROBLEM TO BE SOLVED: To perform much more effective information recommendation under the consideration of a combination of transition source/transition destination domains.SOLUTION: An information recommendation device includes: an access history database 200 for storing access history data of user's access to an item; a transition matrix creation part 101 for creating a transition matrix indicating an access relation between the user and the item by using the access history database 200; a domain combination weight calculation part 102 for calculating an inter-domain transition number by using the access history database 200, and for calculating a domain combination weight by which the partial matrix of each domain combination in the transition matrix is multiplied on the basis of the transition number; and a partial matrix weighting calculation part 104 for weighting the partial matrix by using the domain combination weight.
