Abstract

Provided is a content selection system comprising a content selecting device which selects more than one content from a plurality of contents using selectively and sequentially any one of a plurality of selection standards that are mutually different from each other, and a controlling device which uses a selection standard different from a selection standard used for selecting said more than one content so that the content selecting selects more than one content from the plurality of contents when the content selecting uses any one of the selection standards and there is an operation to indicate a user'"'"'s prescribed evaluation on any of more than one content to be reproduced.

Claims

1. A content selection system comprising:

a content selecting device which selects more than one content from a plurality of contents using selectively and sequentially any one of a plurality of selection standards that are mutually different from each other; and

a controlling device which uses a selection standard different from a selection standard used for selecting said more than one content so that the content selecting selects more than one content from the plurality of contents when the content selecting uses any one of the selection standards and there is an operation to indicate a user'"'"'s prescribed evaluation on any of more than one content to be reproduced.

2. The content selection system according to claim 1, wherein

when it is satisfied with condition to end content selection using any of the selection standard, the controlling device uses a selection standard different from said selection standard so that the content selecting device selects more than one content.

3. The content selection system according to claim 1 or 2, further comprising

a content reproducing device that reproduces said more than one content when the content selecting uses any of selection standards to select more than one content.

4. The content selection system according to any one of claims 1 to 3, wherein

the plurality of selection standards includes a first selection standard, and

the controlling device uses the first selection standard so that the content selecting device to select more than one content when there is an operation to indicate an user'"'"'s positive evaluation on any of more than one content that is selected using a selection standard other than the first selection standard.

5. The content selection system according to claim 4, wherein

the first selection standard uses a first attribute of a content which corresponds to the operation indicating a positive evaluation.

6. The content selection system according to claim 4 or 5, further comprising

a short-term positive feature vector storing device that stores more than one short-term positive feature vector based on features of a content corresponding to each of more than one positive operation during a prescribed period after an operation indicating an user'"'"'s positive evaluation,

wherein the first selection standard uses the more than one short-term positive feature vector that is stored by the storing device.

7. The content selection system according to any one of claims 4 to 5, wherein

the plurality of selection standards includes a second selection standard, and

the controlling device uses the second selection standard so that the content selecting device to select more than one content when ending reproducing of the more than one content that is selected using the first selection standard.

8. The content selection system according to claim 7, wherein

the content selection system uses a second attribute different from the first attribute of a content corresponding to the second selection standard and the operation indicating a positive evaluation.

9. The content selection system according to any one of claims 1 to 8, wherein

the plurality of selection standards includes a third selection standard, and

the controlling device uses the third selection standard so that the content selecting device to select more than one content when there is an operation to indicate an user'"'"'s negative evaluation on any of more than one content that is selected using a selection standard other than the third selection standard.

10. The content selection system according to claim 9, wherein

the third selection standard uses random numbers.

11. A content selection method comprising:

a content selecting step which selects more than one content from a plurality of contents using selectively and sequentially any one of a plurality of selection standards that are mutually different from each other; and

a controlling step which uses a selection standard different from a selection standard used for selecting said more than one content so that the content selecting selects more than one content from the plurality of contents when the content selecting uses any one of the selection standards and there is an operation to indicate a user'"'"'s prescribed evaluation on any of more than one content to be reproduced.

12. A content selection apparatus comprising:

a query generating device which generates a query to select more than one content from a plurality of contents using selectively and sequentially any one of a plurality of selection standards that are mutually different from each other; and

a controlling device that controls generating a query for selecting more than one content from the plurality of contents using a selection standard different from a selection standard used for selecting the more than one content when there is an operation which is selected by a query generated by the query generating device and which indicates a user'"'"'s prescribed evaluation on any of the more than one content to be reproduced.

13. A program to cause a computer to function as:

a query generating device which generates a query to select more than one content from a plurality of contents using selectively and sequentially any one of a plurality of selection standards that are mutually different from each other; and

a controlling device that controls generating a query for selecting more than one content from the plurality of contents using a selection standard different from a selection standard used for selecting the more than one content when there is an operation which is selected by a query generated by the query generating device and which indicates a user'"'"'s prescribed evaluation on any of the more than one content to be reproduced.
