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:

a degree of activity database configured to manage a degree of activity calculated based on one or more operations performed by a user on a predetermined item, the degree of activity reflecting the user'"'"'s interest or taste at the time of performing the one or more operations;

a first extracting unit configured to extract a first recommendation list, the first recommendation list including items from a recommendation list based on the degree of activity;

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

a second extracting unit configured to calculate a degree of similarity between the managed taste and each of the items from the recommendation list to extract a second recommendation list, the second recommendation list including items from the recommendation list with a high degree of similarity; and

one or more item recommending units configured to recommend one or more items among the items in the first recommendation list and the second recommendation list to the user.

2. The information processing apparatus according to claim 1, wherein the degree of activity is calculated by adding values pre-set for each respective operation of recording, viewing, and transferring the corresponding item to another apparatus.

3. The information processing apparatus according to claim 1, wherein the degree of activity is attenuated at predetermined intervals.

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

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

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

managing, using at least one processing unit, a degree of activity calculated based on one or more operations performed by a user on a predetermined item, the degree of activity reflecting the user'"'"'s interest or taste at the time of performing the one or more operations;

extracting a first recommendation list, the first recommendation list including items from a recommendation list based on the degree of activity;

managing taste of the user, the taste being stored in storing means;

calculating a degree of similarity between the managed taste and each of the items from the recommendation list to extract a second recommendation list, the second recommendation list including items from the recommendation list with a high degree of similarity; and

recommending one or more items among the items in the first recommendation list and the second recommendation list to the user.

6. The method according to claim 5, wherein the degree of activity is calculated by adding values pre-set for each respective operation of recording, viewing, and transferring the corresponding item to another apparatus.

7. The method according to claim 5, wherein the degree of activity is attenuated at predetermined intervals.

8. The method according to claim 5, further comprising:

calculating a value indicating to what extent viewing in series is recommended and multiplying each of the degree of similarity by the calculated value.

9. A non-transitory computer-readable recording medium having stored therein a program that, when executed by a computer, causes the computer to execute a process comprising the steps of:

managing a degree of activity calculated based on one or more operations performed by a user on a predetermined item, the degree of activity reflecting the user'"'"'s interest or taste at the time of performing the one or more operations;

extracting a first recommendation list, the first recommendation list including items from a recommendation list based on the degree of activity;

managing taste of the user, the taste being stored in storing means;

calculating a degree of similarity between the managed taste and each of the items included in the recommendation list to extract a second recommendation list, the second recommendation list including items from the recommendation list with a high degree of similarity; and

recommending one or more items among the items in the first recommendation list and the second recommendation list to the user.
