摘　　要：针对当前音乐类作品在线播放系统设计方法存在的搜索效率低和感兴趣程度计算结果准确率低的问题,提出一种计算机制作音乐类作品在线播放系统设计方法。播放系统分为系统与用户管理平台、音乐类作品管理平台和音乐类作品采编平台。通过系统与用户管理平台对用户的权限和真伪进行辨别,在音乐类作品采编平台实现音乐类作品的下载和上传,通过音乐类作品管理平台对音乐类作品进行编目管理、转码服务和迁移管理。根据用户作品矩阵构建用户-音乐类作品关联表,对目标用户和其他用户之间存在的相似度进行计算,根据计算结果进行排列,得到与目标用户之间相似度最高的最近邻居集合,选出用户喜欢的音乐类作品。通过UserCF算法计算用户对作品的感兴趣程度,生成音乐类作品的推荐T列表,完成计算机制作音乐类作品在线播放系统的设计。实验结果表明,所提方法的搜索效率高、感兴趣程度计算结果准确率高。Since the current design method of the online play system for music works has the problems of low search effi-ciency and low accuracy of interest degree calculation results,a design method for the online play system of computer-made mu-sic works is proposed.The play system is composed of the system and user management platform,music work management plat-form,and music work collecting and editing platform.The system and user management platform is used to identify the user′s right and authenticity.The music work collecting and editing platform is used to realize download and upload of music works.The music work management platform is used to conduct catalogue management,transcoding service and migration management of music works.The user-music work association list is constructed based on the user′s work matrix.The similarity degrees be-tween the target users and other users are calculated.The calculation results are ranked to obtain the nearest neighbor set of the target users with the highest similarity,so as to select the music works that the users like.The UserCF algorithm is used to cal-culate the users′interest level to the works,so as to generate a recommendation list of music works,and complete the design of the online play system for computer-made music works.The experimental results show that the proposed method has a high search efficiency and high accuracy of interest degree calculation results.
