System for browsing through a music catalog using correlation metrics of a knowledge base of mediasets

Abstract

A system and method to navigate through a media item catalog using correlation metrics (FIGS. 1,2 ) from a knowledge base ( 400 ) of mediasets (FIG. 4, 1 - 7 ). The system uses a knowledge base consisting of a collection of mediasets. Various metrics (Metric 1 -Metric m) among media items (m 1 . . . ) 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 ).

1 . A method of assisting a user in browsing in an electronic catalog of media items, the method comprising:
 (a) obtaining access to co-concurrency metric values derived from a knowledge base of mediasets associated with the electronic catalog; 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 the co-concurrency metric values are independent of the content of the media items; 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, rating, classification or attribute of the media items' content;   (b) receiving an initial selection of at least one media item from the catalog to define an initial input media set;   (c) for each item of the initial input media set, generating at least one navigation list based on the co-concurrency metric values;   (d) communicating the generated navigation list to a user;   (e) receiving from the user an instruction to edit the navigation list;   (f) editing the navigation list as instructed by the user to define a new input set;   (g) responsive to the new input media set, generating a new navigation list based on the co-concurrency metric values; and   (h) communicating the new navigation list to the user.
