Apparatus and method for presenting contents in relation to a search axis
First Claim
1. An information processing apparatus, comprising:
- a memory storing a program; and
a processor configured to execute the program to cause the information processing apparatus to;
create a first function relating feature quantities of first contents to first values of said first contents, said first created function being based on said feature quantities of said first contents and histories of reproduction of said first contents by a user;
create a second function relating feature quantities of said first contents to second values of said first contents, said second created function being based on feature quantities of first contents and evaluations of said first contents by said user;
calculate, using the first created function, first expected values of second contents based on feature quantities of said second contents;
calculate, using the second created function, second expected values of said second contents based on said feature quantities of said second contents; and
control display of a presentation of said second contents in relation to a first search axis and a second search axis in a two-dimensional space, said second contents being positioned along a direction of said first search axis based on said calculated first expected values and along a direction of said second search axis based on said second expected values,whereinsaid feature quantities are determined based on metadata associated with said first or second contents, andat least one of said feature quantities used to create said second function differs from feature quantities used to create said first created function.

Abstract
An information processing apparatus is disclosed. The apparatus may include a memory storing a program. The apparatus may also include a processor configured to execute the program to cause the apparatus to perform a method. The method may include creating a function relating feature quantities of first contents to known values of the first contents. The method may also include calculating, using the created function, expected values of second contents based on feature quantities of the second contents. In addition, the method may include controlling display of a presentation of the second contents in relation to a search axis, the second contents being positioned along a direction of the search axis based on the calculated expected values.

6. An information processing method, comprising the steps of:
-
creating a first function relating feature quantities of first contents to first values of said first contents, said first created function being based on said feature quantities of said first contents and histories of reproduction of said first contents by a user; creating a second function relating feature quantities of said first contents to second values of said first contents, said second created function being based on feature quantities of first contents and evaluations of said first contents by said user; calculating, using the first created function, first expected values of second contents based on feature quantities of said second contents; calculating, using the second created function, second expected values of said second contents based on said feature quantities of said second contents; and controlling display of a presentation of said second contents in relation to a first search axis and a second search axis in a two-dimensional space, said second contents being positioned along a direction of said first search axis based on said calculated first expected values and along a direction of said second search axis based on said second expected values, wherein said feature quantities are determined based on metadata associated with said first or second contents, and at least one of said feature quantities used to create said second function differs from feature quantities used to create said first created function.

7. A non-transitory computer-readable storage medium storing a program that, when executed by a processor, causes a computer to carry out a process, the process comprising the steps of:
-
creating a first function relating feature quantities of first contents to first values of said first contents, said first created function being based on said feature quantities of said first contents and histories of reproduction of said first contents by a user; creating a second function relating feature quantities of said first contents to second values of said first contents, said second created function being based on feature quantities of first contents and evaluations of said first contents by said user; calculating, using the created function, expected values of second contents based on feature quantities of said second contents; calculating, using the second created function, second expected values of said second contents based on said feature quantities of said second contents; and controlling display of a presentation of said second contents in relation to a first search axis and a second search axis in a two-dimensional space, said second contents being positioned along a direction of said first search axis based on said calculated first expected values and along a direction of said second search axis based on said second expected values, wherein said feature quantities are determined based on metadata associated with said first or second contents, and at least one of said feature quantities used to create said second function differs from feature quantities used to create said first created function.

8. An information processing apparatus, comprising:
-
creation means for creating a first function relating feature quantities of first contents to first values of said first contents, said first created function being based on said feature quantities of said first contents and histories of reproduction of said first contents by a user; creation means for creating a second function relating feature quantities of said first contents to second values of said first contents, said second created function being based on feature quantities of first contents and evaluations of said first contents by said user;
calculating means for calculating, using the first created function, first expected values of second contents based on feature quantities of said second contents;calculating means for calculating, using the second created function, second expected values of said second contents based on said feature quantities of said second contents; and display control means for controlling display of a presentation of said second contents in relation to a first search axis and a second search axis in a two-dimensional space, said second contents being positioned along a direction of said first search axis based on said calculated first expected values and along a direction of said second search axis based on said second expected values, wherein said feature quantities are determined based on metadata associated with said first or second contents, and at least one of said feature quantities used to create said second function differs from feature quantities used to create said first created function.
