AI总结:

针对自动作文评分中不同提示处理的挑战,本文结合有监督特征法和LLM法,将语言特征融入LLM评分,提出的混合方法在域内和域外提示上均优于基线模型。

摘要:

自动作文评分(AES)为学生作文分配分数,减轻教师的评分工作量。由于写作任务的灵活性和多样性,开发能处理不同提示作文的评分系统具有挑战性。现有方法通常分为两类:有监督的基于特征的方法和基于大语言模型(LLM)的方法。有监督的基于特征的方法常能获得更高性能,但需要资源密集型训练;相比之下,基于LLM的方法在推理时计算效率高,但往往性能较低。本文通过将语言特征融入基于LLM的评分来结合这两种方法,实验结果表明,该混合方法在域内和域外写作提示上均优于基线模型。

英文摘要:

Automatic Essay Scoring (AES) assigns scores to student essays, reducing the grading workload for instructors. Developing a scoring system capable of handling essays across diverse prompts is challenging due to the flexibility and diverse nature of the writing task. Existing methods typically fall into two categories: supervised feature-based approaches and large language model (LLM)-based methods. Supervised feature-based approaches often achieve higher performance but require resource-intensive training. In contrast, LLM-based methods are computationally efficient during inference but tend to suffer from lower performance. This paper combines these approaches by incorporating linguistic features into LLM-based scoring. Experimental results show that this hybrid method outperforms baseline models for both in-domain and out-of-domain writing prompts.
