ABSTRACT:
Methods and systems verify and control the quality of metadata associated with a media data file. The metadata may be used, for example, by media content recommendation systems. In one embodiment, a first attribute is selected from metadata associated with a media data file and an attribute dependency corresponding to the first attribute is determined. The metadata may be searched to determine whether it includes a second attribute that satisfies the dependency. If the dependency is not satisfied, the metadata is flagged for reevaluation. The metadata may also be flagged for reevaluation, for example, if the metadata includes inconsistent attributes, if the total number of assigned attributes within the metadata does not exceed a predetermined value, or if an expected attribute dimension is missing or does not include an expected number of defined attributes. In certain embodiments, user selections are controlled to provide consistent attribute combinations.
