青歌赛评分机制的公平性研究—基于评委情感因素过滤的视角

Research of Fair Grading Mechanism in Youth Singer Competition—Based on the Commentators Affective Filter

摘要: CCTV青年歌手电视大奖赛自举办以来，评分机制一直是争议颇多的一大问题，评分的客观公正与否直接关系到比赛的公平性。针对这一问题，从评委情感因素过滤的视角提出了一种评价模型。该模型的基本原理是首先给定参赛选手一个待定的虚拟得分值向量，然后以虚拟得分值与评委群体评分值向量的贴近度最大为基准，对虚拟得分值进行循环优化，使其不断接近于参赛选手的客观表现。最后，通过一个模拟算例验证了带有情感过滤特征评价模型的有效性。

Abstract: There is always a dispute about scoring mechanism of the Youth Singer Competition which is held by CCTV in China, because the scoring objectivity is related to competition fairness directly. To this problem, we present one scoring model associated with the commentators’ affective filter. The basic principle of this model is as follows. First, each competitor is given a fictitious scoring vector. Second, the fictitious scoring vector is optimized repeatedly through the maximal approaching degree between the fictitious and the group scoring vector. At last, a simulation example is given to illustrate the validity of the affective filter scoring model.
