A device for generating metadata for a programming event receives data corresponding to a programming event that includes descriptive information and timing information. The device analyzes the data to determine goodness of fit scores for the programming event corresponding to categories of a classification hierarchy. The device then stores metadata for the programming event that includes goodness of fit scores, time data and descriptive data. The stored goodness of fit scores may be a representative subset of all goodness of fit scores for the programming event. Also disclosed are processes performed in a device for generating metadata for programming events. Also disclosed is metadata encoded in a computer readable medium. The metadata includes a programming event identifier, descriptive data describing the programming event, time data enabling determination of a start time and duration of the programming event, and goodness of fit scores for the programming event that are associated with categories of the classification hierarchy.
