Abstract: A region linear model optimization system optimizes a region linear model, and includes: a linear model setting unit 81 for setting for a partition a linear model to be applied to one of regions representing subspaces divided by the partition, the partition being an indicator function dividing an input space into two portions; and a region model calculation unit 82 for representing a model of each of the regions in the region linear model as a linear combination of the linear models to be applied to the respective regions.

Abstract: Even if the number of documents for the number of words is insufficient, appropriate similarity degree learning is performed. An analysis method by a topic model is used to perform learning of a degree of similarity between recruitment information and resume information. By analyzing recruitment information registered with a recruitment card database DB 310 and resume information registered with a resume database DB 320 using a topic model, a characteristics extracting portion 330 collects words (keywords) extracted from documents constituting the recruitment information and the resume information for each topic; and a similarity degree learning portion 360 performs similarity degree learning for each topic.
