Abstract:
1. An information processing apparatus comprising: a correction device comprising at least one processor for correcting item feature quantities representing, as an item, calculated content features of a recommendation target item for which a recommendation process for recommending an item having features resembling those of the recommendation target item is performed by using user preferences representing preferences of a recommendation target user who is a party to whom the item is recommended with respect to the item, wherein the user preferences are determined based on a list of content or metadata previously selected or viewed by the recommendation target user, and wherein correcting comprises modifying calculated content feature quantities based on the determined user preferences; a preference storage device for storing predetermined preferences common to all users, wherein the correction device, when user preferences representing a particular recommendation target user are unavailable, obtains the predetermined preferences from the preference storage device, and corrects the item feature quantities of the recommendation target item by using the obtained predetermined preferences; a matching device comprising at least one processor for comparing the item feature quantities corrected by the correction with the item feature quantities of another item and for searching for another item having item feature quantities that resemble those of the recommendation target item, wherein the matching device includes a degree of similarity calculation device for calculating a degree of similarity between the item feature quantities of the recommendation target item and the item feature quantities of another item, and a degree of similarity holding device for holding the degree of similarity calculated by the degree of similarity calculation device; and a recommendation device for recommending related items having features resembling those of the recommendation target item on the basis of the result of the matching by the matching device.
