摘要
采用目前方法设计直播课程评分系统,在实现过程中没有应用层次关联理论,导致评分均方根误差大、评分自由度高和系统运行效率低,因此,提出微信公众号直播课程线上评分系统的设计。由视频直播系统和线上评分系统构成线上评分系统的整体架构,根据评分指标,参考专家评审意见,通过层次关联理论计算直播课程评分权重,完成微信公众号直播课程线上评分系统的设计。实验结果表明,所提方法的均方根误差均在0.02以内,误差小;评分自由度均在10%以下,拟合效果好;运行时间均小于1 min,系统运行效率高。
In designing the live course scoring system by current methods,there is no application of the theory of hierarchical connection,which leads to the large root mean square error of the score,the high variance of the score and the low efficiency of the system.Therefore,a design method of the online evaluation system for WeChat official account live broadcast is proposed.The overall structure of the online scoring system is composed,including the video live broadcast system and the online scoring system.According to the scoring index and expert evaluation opinions,the scoring weights of the live broadcast course are determined through hierarchical correlation theory,and the design of the online scoring system of WeChat official account live broadcast course is completed.The experimental results show that the root mean square error of the proposed method is within 0.02;the scoring variance is below 10%,and it has a good fitting effect;the running time is less than 1 min,and the operating efficiency of the system is high.
