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 from the user 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 the 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) for each item of 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.

Abstract
A system 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 (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).

13. 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, rating, 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. - View Dependent Claims (14, 15, 16, 17)
