Patent ID: 7296031

Claim:
A system that facilitates generating lists, the system comprising: a media library data store that stores client items; a reference metadata database that stores descriptive metadata associated with client items; an identifying system operable to associate descriptive metadata with client items; and a list generation system operably connected to the media library data store and the client item descriptive metadata data store, the list generation system comprising: a seed item input subsystem adapted to receive at least one seed item; a similarity subsystem operable to produce a similarity value that characterizes the degree to which a candidate client item and the seed item are similar, wherein the similarity subsystem accepts as inputs a feature vector associated with a candidate user item and a feature vector associated with the seed item and produces a difference vector, where the difference vector can be input to a similarity value generator, the similarity value generator producing the similarity value; and a list generating subsystem operably connected to the similarity subsystem, the list generating subsystem producing a list based, at least in part, on the degree to which candidate client items are related to the at least one seed item.
