First Claim
Patent Images
1. A method comprising:
- storing a plurality of media sets in a knowledge base of media sets; and
preprocessing the knowledge base to quantify an association between pairs of media items in the knowledge base, comprising;
for each item in a mediaset, identifying every other item in the same mediaset, so as to define all of the pairs of media items in that mediaset;
repeating said identifying step for every other mediaset in the knowledge base, thereby defining every pair of items that appears in any mediaset in the knowledge base; and
for each identified pair of media items, adjusting a concurrency metric value responsive to each additional occurrence of the same pair of items in the knowledge base.

Abstract
Systems and methods are disclosed for identifying a new set of media items in response to an input set (or “query set”) of media items and knowledge base metrics. The system uses a knowledge base consisting of a collection of mediasets. Various metrics among media items are considered by analyzing how the media items are grouped to form the mediasets in the knowledge base. Such association or “similarity” metrics are preferably stored in a matrix form that allows the system to efficiently identify a new set of media items that complements the input set of media items.

9. A system for preprocessing a knowledge base for sending media recommendations comprising:
-
a database for storing a plurality of media sets in a knowledge base of media sets; and a processor for preprocessing the knowledge base to quantify an association between pairs of media items in the knowledge base, wherein the processor is further configured to; for each item in a mediaset, identify every other item in the same mediaset, so as to define all of the pairs of media items in that mediaset; repeat said identifying step for every other mediaset in the knowledge base, thereby defining every pair of items that appears in any mediaset in the knowledge base; and for each identified pair of media items, adjust a concurrency metric value responsive to each additional occurrence of the same pair of items in the knowledge base. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 21, 22, 23, 24)

17. A non-transitory computer-readable medium comprising:
-
a medium configured to store computer-readable instructions thereon; and the computer-readable instructions that, when executed by a processing device cause the processing device to perform a method, comprising; storing a plurality of media sets in a knowledge base of media sets; and preprocessing the knowledge base to quantify an association between pairs of media items in the knowledge base, comprising; for each item in a mediaset, identifying every other item in the same mediaset, so as to define all of the pairs of media items in that mediaset; repeating said identifying step for every other mediaset in the knowledge base, thereby defining every pair of items that appears in any mediaset in the knowledge base; and for each identified pair of media items, adjusting a concurrency metric value responsive to each additional occurrence of the same pair of items in the knowledge base. - View Dependent Claims (18, 19, 20)
