Abstract

An approach is provided for finding users with similar media interest. A media service platform retrieves a first media profile of a first user and a second media profile of a second user, wherein each of the profiles includes information of a plurality of media parameters and playback data relating to at least one of the plurality of media parameters. Next, the media service computes similarity values between the first user and the second user based on the weighted playback data of the media profiles. The media service platform then determines a similarity score between the first user and the second user using the similarity values.

Claims

1. A method comprising:

retrieving a first media profile of a first user and a second media profile of a second user, wherein each of the profiles includes information of a plurality of media parameters and playback data relating to at least one of the plurality of media parameters;

computing similarity values between the first user and the second user based on the playback data of the media profiles; and

determining a similarity score between the first user and the second user using the similarity values.

2. A method of claim 1, further comprising:

weighting the playback data based on time,

wherein the similarity values are computed based on the weighted playback data.

3. A method of claim 2, wherein the weighting includes:

updating the playback data by weighting the playback data with an amount of time passed since a previous update; and

adding the updated playback data to a currently-acquired playback data.

4. A method of claim 1, wherein the weighting includes multiplying the playback data by a relevance factor, the relevance factor being greater for more recent playback data.

5. A method of claim 1, wherein the plurality of media parameters includes at least one of titles, artists, genres, musical instruments, actors, actresses, authors, a mood of media and a number of beats.

6. A method of claim 1, wherein the each of the similarity values is computed using a cosine similarity method on a first vector corresponding to the first user and a second vector corresponding to the second user, each of the first and second vectors being defined by the weighted playback.

7. A method of claim 1, wherein determining the similarity score includes:

weighting the similarity values by multiplying each similarity value by a respective score weight; and

summing the weighted similarity values to determine the similarity score.

8. A method of claim 1, further comprising:

determining whether to establish a relationship between the first user and the second user in a social networking service based on the similarity score; and

causing, at least in part, establishment of the relationship based on the determination.

19. A computer-readable storage medium of claim 6, wherein the apparatus is further caused to perform:

weighting the playback data based on time,

wherein the similarity values are computed based on the weighted playback data.

20. A computer-readable storage medium of claim 6, wherein determining the similarity score includes causing the apparatus to perform:

weighting the similarity values by multiplying each similarity value by a respective score weight; and

summing the weighted similarity values to determine the similarity score.

9. An apparatus comprising:

at least one processor; and

at least one memory including computer program code,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,

retrieve a first media profile of a first user and a second media profile of a second user, wherein each of the profiles includes information of a plurality of media parameters and playback data relating to at least one of the plurality of media parameters,

compute similarity values between the first user and the second user based on the weighted playback data of the media profiles, and

determine a similarity score between the first user and the second user using the similarity values.

10. An apparatus of claim 9, wherein the apparatus is further caused to:

weight the playback data based on time,

wherein the similarity values are computed based on the weighted playback data.

11. An apparatus of claim 10, wherein weighting of the playback data includes causing the apparatus to:

update the playback data by weighting the playback data with an amount of time passed since a previous update; and

add the updated playback data to a currently-acquired playback data.

12. An apparatus of claim 9, wherein weighting of the playback data includes causing the apparatus to:

multiply the playback data by a relevance factor, the relevance factor being greater for more recent playback data.

13. An apparatus of claim 9, wherein the plurality of media parameters includes at least one of titles, artists, genres, musical instruments, actors, actresses, authors, a mood of media and a number of beats.

14. An apparatus of claim 9, wherein the each of the similarity values is computed using a cosine similarity method on a first vector corresponding to the first user and a second vector corresponding to the second user, each of the first and second vectors being defined by the weighted playback data.

15. An apparatus of claim 9, wherein determining the similarity score includes causing the apparatus to:

weight the similarity values by multiplying each similarity value by a respective score weight; and

sum the weighted similarity values to determine the similarity score.

16. An apparatus of claim 9, wherein the apparatus is further caused to:

determine whether to establish a relationship between the first user and the second user in a social networking service based on the similarity score; and

cause, at least in part, establishment of the relationship based on the determination.

17. An apparatus of claim 9, wherein the apparatus is a mobile phone further comprising:

user interface circuitry and user interface software configured to facilitate user control of at least some functions of the mobile phone through use of a display and configured to respond to user input; and

a display and display circuitry configured to display at least a portion of a user interface of the mobile phone, the display and display circuitry configured to facilitate user control of at least some functions of the mobile phone.

18. A computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform the following steps:

retrieving a first media profile of a first user and a second media profile of a second user, wherein each of the profiles includes information of a plurality of media parameters and playback data relating to at least one of the plurality of media parameters;

computing similarity values between the first user and the second user based on the weighted playback data of the media profiles; and

determining a similarity score between the first user and the second user using the similarity values.
