摘要
针对目前没有公认的模型可靠地描述用户参数的问题,提出了在MPEG-21(Moving P icture ExpertsG roup 21)下基于统计矢量矩阵和交互式管理相结合的方法,并通过数字项调节和代理的协作将用户参数的描述和管理在一个模型中实现。由于对于用户参数的管理与多媒体应用系统是分开进行的,从而提高了多媒体应用系统的效率。仿真结果表明,该方法能够对于80%左右的相似性用户参数选择进行有效归类和管理。
There is no accepted model to provide formal and reliable representation so far and the method based on combination of SVM (Statistical Vector Matrix) and interactive management is presented aimed at this in MPEG-21 ( Moving Picture Experts Group 21 ), which will categorize the same or similar users' choices according to their priorities systematically and integrate user preferences into one model through the collaboration of digital item adaptation and agent and the management of user preferences is implemented separately from multimedia application system to improve the efficiency. The simulation results show that the method will be effective in utilizing and classifying user preferences based on almost 80% similarities of user preferences in MPEG-21.
