The present invention provides a content evaluation apparatus and a content evaluation method that can distribute contents that a user potentially needs without any omissions. A history class separation unit 203 generates a separation plane for separating in a separation plane a characteristic vector of a selected content and characteristic vectors of non-selected contents stored in a browsing history table 207c. A user characteristic vector calculation unit 204 generates a user characteristic vector based on an orthogonal vector perpendicular to the separation plane thus generated and stores the user characteristic vector in a user characteristic vector management table 207a. Subsequently, when a recommendation request receiving unit 202 receives a recommendation request, a content evaluation unit 206 evaluates the contents based on the stored user characteristic vector. |
