Abstract

A system and method are provided for matching participants in a Peer-to-Peer (P2P) recommendation network that is loosely coupled to a subscription music service. In general, the system includes a central server and a number of peer devices. For each of the peer devices, an associated user is either a subscriber to the subscription music service or a non-subscriber. When a user of a peer device desires to identify new friends with which to exchange recommendations in the P2P recommendation network, a friend recommendation function of the central server identifies new friends for the user of the peer device based on the user'"'"'s status as either a subscriber or a non-subscriber to the subscription music service.

Claims

if the user of the first peer device is a subscriber of the at least one of the number of subscription media services, selecting the new friend for the user of the first peer device from users of other ones of the plurality of peer devices that are also subscribers of the at least one of the number of subscription media services, wherein selecting the new friend comprises;

comparing a user profile of the user of the first peer device to user profiles of users of the other ones of the plurality of peer devices that are also subscribers of the at least one of the number of subscription media services;

comparing a media collection of the user of the first peer device to media collections of the users of the other ones of the plurality of peer devices that are also subscribers of the at least one of the number of subscription media services; and

selecting one of the users of the other ones of the plurality of peer devices having a user profile that has a high correlation to the user profile of the user of the first peer device and a media collection that has a low correlation to the media collection of the user of the first peer device as the new friend for the user of the first peer device; and

effecting addition of the new friend to the P2P recommendation group of the user of the first peer device such that media recommendations are provided to the first peer device from one of the plurality of peer devices associated with the new friend.

2. The method of claim 1 wherein the one of the plurality of peer devices associated with the new friend provides the media recommendations to the first peer device as media presentations identified by the media recommendations are played by the one of the plurality of peer devices.

generating a score indicative of a similarity of the second statistical information from the one of the user profiles and the first statistical information from the user profile of the user of the first peer device; and

comparing the score to a threshold to determine whether the second statistical information from the one of the user profiles is substantially similar to the first statistical information from the user profile of the user of the first peer device.

10.
