Abstract

Methods of generating a playlist for a user are disclosed. For example, an input seed from the user associated with one or more items in a database is received. The input seed may be a song name or artist name. Characteristics that correspond to the input seed are identified. One or more focus traits based on the characteristics are also identified. Based on the identification of the one or more focus traits, a weighting factor is assigned to at least some of the characteristics. The weighted value of the characteristics that correspond to the input seed and characteristics of items in the database are compared. Based on the comparison, items for the playlist are selected.

Claims

1. A method of generating a playlist for a user, comprising:

receiving an input seed from the user associated with one or more items in a database;

identifying characteristics that correspond to the input seed;

identifying one or more focus traits based on the characteristics;

assigning a weighting factor to at least some of the characteristics based on the identification of the one or more focus traits;

comparing the weighted value of the characteristics that correspond to the input seed and characteristics of items in the database; and

selecting items for the playlist based on the comparison.

2. The method of claim 1 wherein the input seed is a song name.

3. The method of claim 1 wherein the input seed is an artist name.

4. The method of claim 3 wherein the step of identifying characteristics includes generating an average of characteristics of items in the database.

5. The method of claim 4 wherein the step of identifying characteristics further includes assigning a confidence factor to the average of characteristics of items in the database.

6. The method of claim 1 wherein the step of assigning includes assigning an additional weighting factor based on preferences of the user.

7. The method of claim 1 wherein the step of comparing includes comparing the difference between characteristics that correspond to the input seed and characteristics of items in the database.

8. The method of claim 1 wherein the step of selecting includes generating one or more subsets of items in the database associated with the one or more focus traits.

9. The method of claim 8 wherein the step of selecting further includes choosing items for selection from the one or more subsets of items based on aesthetic or regulatory criteria.

10. The method of claim 1 further comprising the step of providing content to the user in accordance with the playlist.

11. The method of claim 10 wherein the step of providing includes streaming the content to the user through a computer network.

12. A computer-readable medium having computer-executable instructions for performing steps comprising:

receiving an input seed from the user associated with one or more items in a database;

identifying characteristics that correspond to the input seed;

identifying one or more focus traits based on the characteristics;

assigning a weighting factor to at least some of the characteristics based on the identification of the one or more focus traits;

comparing the weighted value of the characteristics that correspond to the input seed and characteristics of items in the database; and

selecting items for the playlist based on the comparison.

13. The computer-readable medium of claim 12 wherein the input seed is a song name.

14. The computer-readable medium of claim 12 wherein the input seed is an artist name.

15. The computer-readable medium of claim 14 wherein the step of identifying characteristics includes generating an average of characteristics of items in the database.

16. The computer-readable medium of claim 15 wherein the step of identifying characteristics further includes assigning a confidence factor to the average of characteristics of items in the database.

17. The computer-readable medium of claim 12 wherein the step of assigning includes assigning an additional weighting factor based on preferences of the user.

18. The computer-readable medium of claim 12 wherein the step of comparing includes comparing the difference between characteristics that correspond to the input seed and characteristics of items in the database.

19. The computer-readable medium of claim 12 wherein the step of selecting includes generating one or more subsets of items in the database associated with the one or more focus traits.

20. The computer-readable medium of claim 19 wherein the step of selecting further includes randomly choosing items for selection from the one or more subsets of items based on aesthetic or regulatory criteria.

21. The computer-readable medium of claim 12 further comprising the step of providing content to the user in accordance with the playlist.

22. The computer-readable medium of claim 12 wherein the step of providing includes streaming the content to the user through a computer network.

23. A method of receiving content corresponding to items in a database, comprising:

providing an input seed associated with one or more items in the database;

receiving a playlist of items in the database based on a comparison of weighted values of characteristics that correspond to the input seed and characteristics of items in the database; and

receiving content in accordance with the playlist.

24. The method of claim 23 wherein the input seed is a song name.

25. The method of claim 23 wherein the input seed is an artist name.

26. The method of claim 23 wherein the step of comparing includes comparing the difference between characteristics that correspond to the input seed and characteristics of items in the database.

27. The method of claim 23 wherein the step of receiving content includes receiving a stream of content through a computer network.
