论文摘要
我们提出了一种简单但有效的方法，建议为学生提供高质量和多样性的练习。我们的方法由三个关键组成部分组成：（1）候选生成模块； （2）促进多样性的模块； （3）范围限制模块。提出的方法在召回方面提高了总体建议性能，与基线相比，推荐候选者的多样性增加了0.81 \％。
We propose a simple but effective method to recommend exercises with high quality and diversity for students. Our method is made up of three key components: (1) candidate generation module; (2) diversity-promoting module; and (3) scope restriction module. The proposed method improves the overall recommendation performance in terms of recall, and increases the diversity of the recommended candidates by 0.81\% compared to the baselines.
