Abstract

An information processing apparatus includes a changing unit configured to change content data arranged in a predetermined region to other content data in response to a user request, a counting unit configured to count a remaining number of metadata added to content data remaining unchanged by the changing unit among a plurality of pieces of content data arranged in the predetermined region, and a ranking information generation unit configured to generate ranking information representing a degree of popularity of metadata based on the remaining number of metadata counted by the counting unit.

Claims

1. An information processing apparatus comprising:

a changing unit configured to change content data arranged in a predetermined region to other content data in response to a user request;

a counting unit configured to count a remaining number of metadata added to content data remaining unchanged by the changing unit among a plurality of pieces of content data arranged in the predetermined region; and

a ranking information generation unit configured to generate ranking information representing a degree of popularity of metadata based on the remaining number of metadata counted by the counting unit.

2. The information processing apparatus according to claim 1, wherein the counting unit is configured to count a number of times of addition of metadata added to content data newly arranged in the predetermined region by the changing unit, and to count a number of times of deletion of metadata added to content data deleted from the predetermined region by the changing unit, and

wherein the ranking information generation unit is configured to generate ranking information representing the degree of popularity of the metadata concerning the remaining number based on the remaining number, to generate ranking information representing the degree of popularity of the metadata concerning the number of times of addition based on the number of times of addition, and to generate ranking information representing the degree of popularity of the metadata concerning the number of times of deletion based on the number of times of deletion.

3. The information processing apparatus according to claim 2, further comprising:

a calculation unit configured to calculate a popularity score numerically representing the degree of popularity of metadata,

wherein the calculation unit is configured to calculate the popularity score concerning the remaining number based on the ranking information concerning the remaining number.

4. The information processing apparatus according to claim 3, wherein the calculation unit is configured to calculate the popularity score concerning the remaining number based on the ranking information concerning the remaining number, to calculate the popularity score concerning the number of times of addition based on the ranking information concerning the number of times of addition, and to calculate the popularity score concerning the number of times of deletion based on the ranking information concerning the number of times of deletion.

5. The information processing apparatus according to claim 4, wherein the calculation unit is configured to calculate a total popularity score representing a total degree of popularity of metadata based on the popularity score concerning the remaining number, the popularity score concerning the number of times of addition, and the popularity score concerning the number of times of deletion.

6. The information processing apparatus according to claim 5, wherein the calculation unit is configured to calculate the total popularity score by applying, to the popularity score concerning the remaining number, a weight varying with elapsed time.

7. The information processing apparatus according to claim 5, wherein the calculation unit is configured to calculate the total popularity score by applying, to the popularity score concerning the remaining number, a weight varying with usage rate of metadata.

8. The information processing apparatus according to claim 5, further comprising:

a display unit configured to display a list of information representing metadata added to content data on a display device in response to a user request,

wherein the display unit is configured to change a font size of the information representing the metadata contained in the list based on the total popularity score of metadata calculated by the calculation unit.

9. The information processing apparatus according to claim 5, further comprising:

a display unit configured to display a list of content data on a display device in response to a user request,

wherein the display unit changes a display size of content data having the metadata added thereto contained in the list based on the total popularity score calculated by the calculation unit.

10. An information processing apparatus comprising:

a changing unit configured to change content data arranged in a predetermined region to other content data in response to a user request;

a counting unit configured to count a remaining number of content data remaining unchanged by the changing unit among a plurality of pieces of content data arranged in the predetermined region; and

a ranking information generation unit configured to generate ranking information representing a degree of popularity of content data based on the remaining number of content data counted by the counting unit.

11. An information processing method for an information processing apparatus, the information processing method comprising:

changing content data arranged in a predetermined region to other content data in response to a user request;

counting a remaining number of metadata added to content data remaining unchanged among a plurality of pieces of content data arranged in the predetermined region; and

generating ranking information representing a degree of popularity of metadata based on the counted remaining number of metadata.

12. An information processing method for an information processing apparatus, the information processing method comprising:

changing content data arranged in a predetermined region to other content data in response to a user request;

counting a remaining number of content data remaining unchanged among a plurality of pieces of content data arranged in the predetermined region; and

generating ranking information representing a degree of popularity of content data based on the counted remaining number of content data.

13. A computer-readable storage medium storing a program for causing a computer to perform a method comprising:

changing content data arranged in a predetermined region to other content data in response to a user request;

counting a remaining number of metadata added to content data remaining unchanged among a plurality of pieces of content data arranged in the predetermined region; and

generating ranking information representing a degree of popularity of metadata based on the counted remaining number of metadata.

14. A computer-readable storage medium storing a program for causing a computer to perform a method comprising:

changing content data arranged in a predetermined region to other content data in response to a user request;

counting a remaining number of content data remaining unchanged among a plurality of pieces of content data arranged in the predetermined region; and

generating ranking information representing a degree of popularity of content data based on the counted remaining number of content data.
