LONG TAIL MONETIZATION PROCEDURE FOR MUSIC INVENTORIES

摘要

A system and method for constructively providing a monetization procedure for a long tail demand curve of market goods, services or contents in the music industry through a channel such as the Internet or mobile devices, for which there exists a source providing economic scoring (sales, downloads, streaming time, etc.). Using only the scorings for a few reference items and a quantitative concept of similarity between the songs, a procedure is provided that constructively distributes the preference score from the reference items to the non-ranked ones, yielding the full scoring curve adjusted to a long tail law (power law). In order to build preference scores for non-ranked items, the method recursively defines relative preferences between songs based on their similarity, thus constructing a utility-like function. The preferences are then used within an iterative Elo-like tournament strategy between the items.
