An information processing device includes: a candidate generating unit employing a user evaluation matrix of evaluation values indicating evaluations as to multiple contents for multiple users to generate multiple estimated expression candidates which are candidates of an estimated expression employed for estimating an evaluation as to a content of a user; an estimation results computing unit computing the user evaluation matrix by the respective estimated expression candidates to generate an estimation result configured of a predictive evaluation value which is the estimation value of an evaluation value; and an estimated expression selecting unit, in a case where several estimation results are employed, and several estimated expression candidates are employed as estimated expressions, obtaining linear combination coefficients employed for obtaining a final estimation result, and selecting an estimated expression candidate and linear combination coefficient having the highest evaluation as the estimated expression and linear combination coefficient of the next generation.
