SYSTEM FOR BROWSING THROUGH A MUSIC CATALOG USING CORRELATION METRICS OF A KNOWLEDGE BASE OF MEDIASETS
First Claim
1. A computer-implemented method of assisting a user in selecting items from an electronic catalog of media items, the method comprising:
- (a) obtaining access to metric values derived from a knowledge base of predetermined mediasets associated with the electronic catalog;
wherein the metric values reflect a level of association for each of the pairs of media items within the knowledge base of mediasets and the metric values are not affected by any descriptor, characteristic, classification or other descriptive metadata of the media items'"'"' content;
(b) receiving an initial selection of at least one media item to define an initial input media set;
(c) generating an output media item navigation list responsive to at least one item of the input media set, based on the metric values, and the output media item list comprising at least one media item from the electronic catalog; and
(d) communicating the generated navigation list to a user.

Abstract
A system and method to navigate through a media item catalog and generate recommendations using behavioral metrics such as correlation metrics (FIGS. 1,2) from a knowledge base (400) of mediasets (FIG. 4, 1-7). One implementation uses a knowledge base comprising a collection of mediasets. Various metrics (Metric 1-Metric m) among media items (m1 . . . ) are considered by analyzing how the media items are grouped to form the sets in the knowledge base (400). Such metrics preferably are stored in a matrix (100) that allows the system to dynamically build appropriate navigation lists (FIG. 3) from media items that a user selects (FIG. 5).

15. A computer-readable storage medium having computer-readable program code stored therein, said computer-readable program code including:
-
computer-readable program code for receiving a selection of a catalog for user browsing and for accessing a collection of metric data associated with the selected catalog; wherein the metric data comprises metric values for pairs of media items derived from a knowledge base of mediasets; wherein the metric values reflect a level of co-concurrency for each of the pairs of media items within the knowledge base of mediasets; and
further wherein the co-concurrency metric values indicate, for each pair of media items (i,j), how many times item i and item j appear together within any of the mediasets of the knowledge base, so that the co-concurrency metric values are not affected by any descriptor, characteristic, classification or attribute of the media items'"'"' content;computer-readable program code for receiving from the user an initial selection of at least one media item from the selected catalog to define an initial input media set; computer-readable program code for generating a navigation list based on selected metrics for each item of the initial input media set; and computer-readable program code for communicating the generated navigation list to the user.
