摘要:

每四年,OECD会组织PISA测试,评估全球青少年学生的知识水平,并比较教育系统。然而,避免语言差异和标注者偏见使学生答案评分具有挑战性。因此,考虑自动学生答案评分方法是有意义的。为了训练这些方法或计算参数和选择超参数,需要大量领域特定数据。本文探索了使用少量保密数据生成大规模训练数据的几种方法,利用简单衍生文本格式来保持保密性。通过所提出的方法,我们成功创建了三个近似参考数据集,至少在表面相似性上比基于提示的生成结果更接近。初步实验表明,其中一种方法可能有助于改进自动评分模型的训练。

英文摘要:

Every four years, the PISA test is administered by the OECD to test the knowledge of teenage students worldwide and allow for comparisons of educational systems. However, having to avoid language differences and annotator bias makes the grading of student answers challenging. For these reasons, it would be interesting to consider methods of automatic student answer grading. To train some of these methods, which require machine learning, or to compute parameters or select hyperparameters for those that do not, a large amount of domain-specific data is needed. In this work, we explore a small number of methods for creating a large-scale training dataset using only a relatively small confidential dataset as a reference, leveraging a set of very simple derived text formats to preserve confidentiality. Using the proposed methods, we successfully created three surrogate datasets that are, at the very least, superficially more similar to the reference dataset than a straightforward result of prompt-based generation. Early experiments suggest one of these approaches might also lead to improved training of automatic answer grading models.
