Abstract: Systems and methods for selecting media tracks for playback from among a network of accessible media tracks involve providing a probabilistic network of accessible media tracks and a current track from among the tracks in the network. The network comprises, for each individual track, a corresponding plurality of potentially subsequent tracks and a corresponding plurality of selection probabilities, each of the corresponding plurality of selection probabilities indicating a probability that an associated one of the corresponding plurality of potentially subsequent tracks is selected as a subsequent track when the individual track is the current track. The method also involves selecting a first subsequent track from among the plurality of potentially subsequent tracks corresponding to the current track in accordance with the plurality of selection probabilities corresponding to the current track.

Abstract: Systems and methods are provided for organizing a plurality of information objects in a dynamic network. The method involves a network comprising: a plurality of nodes wherein each node represents a corresponding one of the information objects and each node has an associated node strength; and a plurality of links wherein each link represents a connection between a corresponding pair of nodes. The method involves: selecting a first node from among the plurality of nodes to be the currently selected node; and in response to selection of the first node as the currently selected node, increasing the node strength of the first node.
