Abstract: System and method are provided to associate or compare media programs. A method includes: obtaining, using at least one processing circuit, first metadata for a first media program and second metadata for a second media program, wherein the first metadata are organized into a plurality of first fields, and the second metadata are organized into a plurality of second fields; extracting, using at least one processing circuit, a plurality of first tokens from one of the plurality of the first fields and a plurality of second tokens from one of the plurality of second fields; assigning a weight factor to each of the first and second tokens; cross-correlating the first and second tokens between the plurality of first fields and the plurality of second fields; and calculating a similarity score between the first and second media programs based on the cross-correlating.
