PROBLEM TO BE SOLVED: To provide means for calculating a potential feature amount in which a tendency of a user regarding how to give an expression is considered. SOLUTION: An information processing device expresses a variable c representing a user cluster with a random variable following a distribution different by each user, expresses a variable y representing a topic on content items with a random variable following a distribution different by each content, expresses a variable x representing an expression cluster with a random variable following a distribution different by each combination of a user cluster and a topic, calculates, based on a probability model in which a variable a representing an expression of a user is expressed with a random variable following a distribution different by each expression cluster, a parameter included in the probability model using a combination of a feature amount of content and an expression given as learning data, and calculates an attribution degree of a user to a user cluster and an attribution degree of an expression to an expression cluster using the parameter.
