Abstract
An application server includes a Semantic Analysis Core Service (SACS) function that communicates with a Semantic Analysis Client (SAC) in a Set Top Box (STB). The SACS groups programs available for rendering to a subscriber into program clusters. The SACS generates the program clusters based on a determined semantic similarity between the programs, and on parameters that indicate a subscriber's preference for certain program content. The program that are semantically similar to existing clusters within a predetermined viewing window are provided to the STB and output to the subscriber on a display as a program preference list or channel line-up. The STB also monitors the subscriber's interaction with the programs and calculates a preference score for each program indicating the subscriber's continuing, or waning, interest in a given program. The preference score is used to update the score of the program cluster to which the program belongs.
