Abstract
Disclosed are a system for recommending a favorite channel/program based on a television (TV) watching pattern and a method thereof. The present invention provides a system and a method for recommending a favorite channel/program by learning a television (TV) watching pattern using a Bayesian network, by extracting recommended candidate favorite channel/programs by applying an entropy theory to the learned Bayesian network, and by applying a fuzzy logic operation to the extracted candidate favorite channel/programs.
Claims16
A system for recommending a favorite channel/program, the system comprising:
- a Bayesian network learning unit to learn a Bayesian network based on received watching pattern information of a user and thereby calculate a first probability value with respect to all of the channels or programs based on the learning result;
- a candidate favorite channel/program extracting unit to extract a candidate favorite channel or a candidate favorite program based on the calculated first probability value;
- a fuzzy logic operation unit to perform a fuzzy logic inference operation with respect to the extracted candidate favorite channel or candidate favorite program, and to calculate a second probability value with respect to each candidate favorite channel or candidate favorite program based on the performance result;
- and
- a favorite channel/program recommending unit to determine a favorite channel or a favorite program according to the watching pattern information of the user based on the calculated first probability value and second probability value.
A method of recommending a favorite channel/program, the method comprising:
- learning a Bayesian network based on received watching pattern information of a user to thereby calculate a first probability value with respect to all of the channels or programs based on the learning result;
- extracting a candidate favorite channel or a candidate favorite program based on the calculated first probability value;
- performing a fuzzy logic inference operation with respect to the extracted candidate favorite channel or candidate favorite program, and calculating a second probability value with respect to each candidate favorite channel or candidate favorite program based on the performance result;
- and
- determining a favorite channel or a favorite program according to the watching pattern information of the user based on the calculated first probability value and second probability value.
