METHOD AND APPARATUS OF ENHANCING ACCURACY OF INFERENCING CONTENTS PREFERENCE OF VIEWER

摘要

The present invention relates to an apparatus and a method to improve the accuracy of inference for content preference of a viewer based on the viewing intention and viewing time of a viewer′s viewing history. The method includes the steps of: calculating the value of experience of a content based on an experience value function which gives a weighted value higher than a directly proportional value to a content having a higher viewing time ratio of a viewer for a broadcasting time of a content than a weighted reference value, and gives a lower weighted value than a directly proportional value to a content having a lower viewing time ratio of a viewer than a weighted reference value; calculating content preference for each predetermined unit-time period based on the experience value of the content; and calculating a final content preference based on the unit-time period content preference and using a time weighted average which grants time weighted values to a content preference for a current unit-time. According to the invention, the inference of preference applies preference changes according to the time of the psychological conditions with regard to the viewer′s content consumption, so that a more accurate current content preference can be obtained, thereby improving the accuracy and satisfaction to recommend the viewer′s customized broadcasts and customized content.
