A Method of Representing Videos Based on User Interest Model in Mobile Multimedia Service

With the arrival of 3G era, video representation based on user interest has been an active research area in the past few years. Contrasting to the traditional approaches, which merely involved the interest of most users (e. g. most visited videos on Youtube), this paper proposes a novel video representing method based on individual interest model which is formed by collecting and analyzing user behaviors. Furthermore, this model can be extended into group interest model by introducing multi-dimension homo-interest sequence. Experiment results from 100 user cases and database of 25 videos show the effectiveness of our method.
