DATA PROCESSING

Disclosed are methods and apparatus for processing correlated metadata (e.g., programmatic metadata relating to one or more episodes of a television show). Mappings, or correlations, between chunks of the metadata that originated from a particular data source and the metadata clusters may be determined and displayed, e.g., on a graphical user interface. Using this display, a user (i.e., a human operator) may detect inconsistencies in the correlated metadata. An inconsistency may be an incorrect mapping, the mapping of more than one of the metadata chunks that originated from the same data source to the same metadata cluster, or that one or more of the metadata chunks have not been mapped to a metadata cluster. The mappings may then be edited so as to remove detected inconsistencies.
