Embodiment Construction

[0017] figure 1 A television program recommender 100 in accordance with the present invention is illustrated. The published television program recommender 100 utilizes the principle of induction to determine a set of television programs that may satisfy the interests of a particular viewer. The present invention monitors a user's viewing history and analyzes the programs the user actually watches (positive examples) and the programs the user does not watch (negative examples). The present invention then determines positive or negative examples by building a decision tree that tries to cover as many positive examples as possible without covering negative examples.

[0018] According to another feature of the present invention, the TV program recommender 100 does not require any explicit profile information from the user to make TV program recommendations. Clear user profile information, if available, can enhance the recommendations produced by television program recommender 1...

Abstract

A method and apparatus are disclosed for recommending television programming using decision trees. Inductive principles are utilized to identify a set of recommended programs that may be of interest to a particular viewer, based on past viewing behavior. A user's viewing history is monitored and the shows that are actually watched by a user (positive examples) and the shows that are not watched by the user (negative examples) are analyzed. For each positive and negative program example (i.e., programs watched and not watched), a number of program attributes are classified in the user profile. The various attributes are then positioned in a hierarchical decision tree based on a ranking of the entropy of each attribute. Each node and sub-node in the decision tree corresponds to a given attribute from the user profile. Each leaf node in the decision tree corresponds to either a positive or negative recommendation for a program mounted at the corresponding leaf node. The decision tree is built using a decision tree process that implements a 'top-down divide and conquer' approach. The decision tree can thereafter be applied to an electronic program guide to make program recommendations.

Description

technical field [0001] The present invention relates to a method and a device for recommending TV programs, in particular to a method and a device for recommending TV programs by using a decision tree. Background technique [0002] Determining television programs of interest to television viewers has become increasingly complex as the television channels available to television viewers has increased, along with the variety of programming content on those channels. Historically, television viewers have determined television programs of interest by analyzing printed television program guides. Typically, such printed television program guides include a grid listing of available television programs arranged by time and date, channel, and title. Due to the proliferation of television programming, it has become impractical to use such printed guides to effectively determine desired television programming. [0003] More recently, television program guides have become available in...
