STATION LIBRARY CREATON FOR A MEDIA SERVICE

摘要

A machine may form all or part of a network-based system configured to provide media service to one or more user devices. The machine may be configured to define a station library within a larger collection of media files. In particular, the machine may access metadata that describes a seed that forms the basis on which the station library is to be defined. The machine may determine a genre composition for the station library based on the metadata. The machine may generate a list of media files from the metadata based on a relevance of each media file to the station library. The machine may determine the relevance of each media file based on a similarity of the media file to the genre composition of the station library as well as a comparison of metadata describing the media file to the accessed metadata that describes the seed.

主权项

1. A method comprising:
accessing seed metadata, the seed metadata describing a seed, the seed being a basis on which a station library is to be defined; generating a station descriptor profile based on the seed metadata, the station descriptor profile defining a genre composition of the station library; generating a candidate set based on the seed metadata, the candidate set comprising a plurality of candidate media files; for each candidate media file in the candidate set:
computing a similarity score associated with the candidate media file, the similarity score including a measure of similarity between the candidate media file and the station descriptor profile;computing one or more boost values associated with the candidate media file based on candidate metadata describing the candidate media file;determining a relevancy score associated with the candidate media file based on the similarity score and the one or more boost values associated with the candidate media file, the relevancy score providing a basis for selecting the candidate media file for inclusion in the station library; and machine-generating a station set including a portion of the candidate set selected based on the relevancy scores associated with the plurality of candidate media files included in the candidate set, the machine-generated station set defining the station library by referencing each candidate media file in the selected portion of the candidate set.
