MEDIA ITEM CLUSTERING BASED ON SIMILARITY DATA
First Claim
1. A computer implemented method for clustering similar media items in a program participant'"'"'s media library comprising:
- dividing a collection of media items that each exist in at least one program participant'"'"'s media library of a population of program participants into canopies comprising respective groups of potentially similar media items;
recursively sub-dividing the media items in each canopy, each recursion producing non-overlapping, increasingly refined, server clusters of media items determined to be similar to other items in a respective server cluster based on a cluster analysis of similarity data derived from the population of program participants;
terminating the recursive sub-dividing responsive to determining that the server clusters produced from the latest recursion each comprise no more than a determined number of media items, resulting in a plurality of lowest-lowest server clusters; and
creating one or more media item clusters for a particular program participant from items present in that program participant'"'"'s media library, comprising;
determining respective participant media item clusters for media items found in that program participant'"'"'s media library from their membership in any of the lowest-level server clusters; and
recursively agglomerating participant clusters that share a common parent server cluster, and which have fewer than a participant cluster minimum number of media items, into respective larger participant clusters until each of those larger participant clusters comprises at least the participant cluster minimum number of media items.

Abstract
Methods and arrangements for facilitating generation of media mixes for a program participant based at least in part on media library inventory information provided by a number of program participants. Those individuals that decide to be program participants are interested in organizing, maintaining and playing their music, based at least in part, on data derived from a population of other participants in the program. A program participant must send, and the system, receive, data representative of that program participant'"'"'s media inventory. The system or program determines a relative similarity of each item from the collection of program participants as compared to each other item and from the similarity information clusters of similar items are identified. The clusters can be used to identify clusters of similar items in an individual program participant'"'"'s media library and therefrom mixes of similar media items can be created.

12. A method of creating mixes of media items from a program participant'"'"'s collection of media items comprising:
-
sending to a server, information describing individual media items of a program participant'"'"'s collection of media items; receiving from the server, data describing clusters of media items contained within the program participant'"'"'s collection of media items, the clusters having been compiled based on an agglomeration of tracks found in hierarchically related clusters of media items in a media item inventory available to the server, the clusters of media items in the inventory having been determined based on a cluster analysis of similarity data derived from a population of program participants; and determining a mix of media items, the mix comprising media items selected from one of the clusters of media items contained within the program participant'"'"'s collection of media items received from the server. - View Dependent Claims (13, 14, 15)

20. A system for clustering similar media items in a program participant'"'"'s media library comprising:
-
a server configured to recursively sub-divide a collection of media items formed from the media items that exist in at least one program participant'"'"'s media library of a population of program participants, each recursive sub-division producing non-overlapping, increasingly refined, server clusters of media items determined to be similar to other items in a respective server cluster based on a cluster analysis of similarity data derived from the media libraries of the population of program participants and to terminate the recursive sub-dividing responsive to a determination that the server clusters produced from the latest recursive sub-division each comprise no more than a determined number of media items; a server configured to create one or more media item clusters for a particular program participant from items present in that program participant'"'"'s media library based on the server clusters, by performing a method comprising;
determining participant clusters for media items from that program participant'"'"'s media library that are found in one or more lowest-level server cluster, and recursively agglomerating, into larger participant clusters, participant clusters that share a common parent server cluster until each of those larger participant clusters comprises at least a determined minimum number of media items; anda media playing device configured to generate a mix of similar media items for playback based on a selection of media items represented in one of the participant clusters. - View Dependent Claims (21, 22, 23, 24)
