摘　　要：针对无线应用环境,提出了无线数字图书馆中的评价排序问题,并给出一种新颖的排序算法,用于无线环境下的评价排序。该算法基于时间补偿思想,能够避免新投票项长期置底现象。理论验证和移动平台下的实验结果表明,所提出的算法能够有效改善无线数字图书馆中的评价排序过程。Focusing on the wireless application environment,the appraising and ranking issue for wireless digital libraries is proposed in this paper.Also,a novel ranking algorithm especially designed for appraising and ranking in wireless environment is given.This algorithm is based on the idea of time compensation,and is able to prevent fresh voting items from being bottom-placed a long period.Theoretical verification and experimental results gained from mobile platform show that the proposed algorithm can effectively improve the appraising and ranking process in wireless digital libraries.
