PROBLEM TO BE SOLVED: To predict behavior of a user by use of a behavior history of the user in a plurality of domains.SOLUTION: A behavior prediction apparatus 100 includes: a data input section 10 for acquiring a user behavior history group; a statistic calculation section 20 which calculates the number of times that a user selects a certain behavior in a certain domain, from the user behavior history group; a model learning section 30 which determines a domain topic which is a topic to be obtained by modeling domain use of the user with one or more mixed patterns, and a topic to be obtained by representing a behavior of the user with the one or more mixed patterns, from the number of times, to learn domain topic-domain use probability, domain-based user-topic attribution probability, and domain-based topic-behavior selection probability; and a data output section 40 which outputs the domain topic-domain use probability, the domain-based user-topic attribution probability, and the domain-based topic-behavior selection probability.SELECTED DRAWING: Figure 2 |
