Abstract
A playlist generator implements a net-based playlist generation process that comprises a multi-stage, hierarchical process. At a highest hierarchical level, the playlist generator applies parameters corresponding to a user's 'general' preferences, wherein the parameters are relatively constant. At a lower level of the hierarchy, the playlist generator applies parameters corresponding to the user's 'specific' preferences, wherein the parameters are dynamic time-dependent or event-dependent. The playlist generator uses the high-level parameters to generate a subset of material from a global collection of material, and applies the lower-level preferences to this subset of material in response to a change in the user's immediate preferences.
