Abstract

An information processing apparatus includes a managing unit that manages a scale calculated based on descriptions of an operation performed on a predetermined item and a series to which the item belongs in association with each other, a first extracting unit that extracts items belonging to the same series as top N series, obtained by sorting the scales, from among a plurality of items, a taste managing unit that manages taste of a user, a second extracting unit that calculates the degree of similarity between the taste managed by the taste managing unit and each item to extract items with higher degrees of similarity, and a recommending unit that recommends a predetermined number of items among the items extracted by the first extracting unit and the items extracted by the second extracting unit to the user.

Claims

1. An information processing apparatus comprising:

managing means for managing a scale calculated based on descriptions of an operation performed on a predetermined item and a series to which the item belongs in association with each other;

first extracting means for extracting a first recommendation list, the first recommendation list including items belonging to the same series as top N series, obtained by sorting the scale, from among items;

taste managing means for managing taste of a user;

second extracting means for calculating the degree of similarity between the taste managed by the taste managing means and each item to extract a second recommendation list, the second recommendation list including items with higher degrees of similarity, the second recommendation list being different from the first recommendation list; and

recommending means for recommending a predetermined number of items among the items in the first recommendation list and the second recommendation list to the user.

2. The apparatus according to claim 1, wherein the scale is calculated by adding values set to respective operations of recording, viewing, and transferring the corresponding item to another apparatus.

3. The apparatus according to claim 1, wherein the scale is attenuated at predetermined intervals.

4. The apparatus according to claim 1, further comprising:

multiplying means for calculating a value indicating to what extent viewing in series is recommended and multiplying each of the degrees of similarity of the items, extracted by the second extracting means, by the calculated value.

5. A computer-implemented method for information processing, comprising the steps of:

referring to information, using at least one processing unit, including a scale calculated based on descriptions of an operation performed on a predetermined item and a series to which the item belongs in association with each other, stored in storing means to extract a first recommendation list, the first recommendation list including items belonging to the same series as top N series, obtained by sorting the scale, from among a plurality of items;

referring to taste of a user, the taste being stored in storing means, and calculating the degree of similarity between the taste and each item to extract a second recommendation list, the second recommendation list including items with higher degrees of similarity, the second recommendation list being different from the first recommendation list; and

recommending the items in the first recommendation list and the second recommendation list to the user.

6. A recording medium having stored therein a non-transitory computer-readable program that allows a computer to execute a process comprising the steps of:

referring to information, including a scale calculated based on descriptions of an operation performed on a predetermined item and a series to which the item belongs in association with each other, stored in storing means to extract a first recommendation list, the first recommendation list including items belonging to the same series as top N series, obtained by sorting the scale, from among a plurality of items;

referring to taste of a user, the taste being stored in storing means, and calculating the similarity between the taste and each item to extract a second recommendation list, the second recommendation list including items with higher degrees of similarity, the second recommendation list being different from the first recommendation list; and

recommending the items in the first recommendation list and the second recommendation list to the user.

7. An information processing apparatus comprising:

a managing unit configured to manage a scale calculated based on descriptions of an operation performed on a predetermined item and a series to which the item belongs in association with each other;

a first extracting unit configured to extract a first recommendation list, the first recommendation list including items belonging to the same series as top N series, obtained by sorting the scale, from among items;

a taste managing unit configured to manage taste of a user;

a second extracting unit configured to calculate the degree of similarity between the taste managed by the taste managing unit and each item to extract a second recommendation list, the second recommendation list including items with higher degrees of similarity, the second recommendation list being different from the first recommendation list; and

a recommending unit configured to recommend a predetermined number of items among the items in the first recommendation list and the second recommendation list to the user.
