Abstract: A program recommendation system employing a plurality of classifier modules is disclosed. In response to a reception of a record corresponding to a program, a classifier module correlated to a programming category indicated by the record as corresponding to the program will generate a recommendation of the program or each classifier module generates a recommendation of the program when the record fails to indicate a programming category corresponding to the program. When multiple recommendations are generated, a program record module of the system ranks the recommendations and utilizes the highest rank recommendation for the program.

Abstract: Methods and apparatuses for recommending television programs are provided. The methods provided include obtaining a list of one or more television programs to at least three different program recommenders, obtaining from each recommender a recommendation score, and computing a combined recommendation score by applying a voting process. The combined recommendation score is then presented to a user, who, based thereon, can select a television program of interest. The voting process is a stochastic method including a Bayesian method, a hierarchical decision tree, a memory based learning process, a rule based learning process, a neural network or a hidden markov model. The enumerated stochastic processes can be further combined according to a combination scheme including a unison scheme, a majority scheme, a trust scheme, an averaging scheme or mixture thereof.

Abstract: A multiple key depressing device for depressing several spaced apart keys on a keyboard of a computer with one hand. The multiple key depressing device includes a support rod with opposite first and second ends, and a pair of spaced apart bends defining first, second, and third elongate portions. A handle designed for grasping by a hand of a user is upwardly extended from the support rod. A plurality of elongate legs downwardly depend from the support rod. Each leg has a lower end adapted for resting on a key of a keyboard of a computer.
