Multi-Dimensional Automated Essay Scoring Based on Disentangled Representation and Collaborative Scoring Mechanism
-
摘要: 多维度作文评分旨在从多个评分维度对作文质量进行细粒度评估, 从而实现更加全面和客观的自动化评价. 现有方法大多基于共享预训练编码器提取统一文本表示, 并在此基础上分别预测各维度得分. 然而, 这种共享表示往往混合了不同评分维度的信息, 导致维度间特征相互干扰, 削弱模型对特定维度差异的感知能力, 进而限制整体评分性能的提升. 为解决上述问题, 提出了一种基于“解耦−协作”机制的多维度特征学习框架, 旨在通过增强维度特征的独立建模能力与跨维度评分协同能力. 首先, 针对共享编码器所产生的特征过度耦合问题, 通过引入大语言模型生成维度特定的质量描述, 并将其作为外部知识信号引导维度表征学习, 从而促进共享表示的解耦. 其次, 为提高多任务学习过程中评分维度间的跨维度协同评分能力, 进一步引入促进评分协作的混合专家机制, 通过动态路由实现维度间的可控信息交互, 在保持维度独立性的同时充分利用跨维度相关信息. 在公开数据集上的实验结果表明, 所提出方法增强了模型对维度特征差异的感知能力, 在整体评分及不同维度的评分上均取得了优于现有方法的性能表现.Abstract: Multi-trait essay scoring aims to evaluate essay quality from multiple scoring dimensions, thereby enabling a more comprehensive and objective automated assessment. Existing approaches rely on a shared pre-trained encoder to extract unified textual representations, upon which trait-specific scores are predicted separately. Such shared representations from different scoring traits are often entangled, leading to inner-trait interference. This interference weakens the model's ability to capture trait-specific distinctions and consequently limits scoring performance. To address these issues, this paper proposes a multi-trait representation learning framework based on a disentanglement-collaboration mechanism, designed to enhance both the independent modeling of trait-specific features and cross-trait collaborative scoring capability. First, to mitigate the over-entanglement problem, this paper incorporates large language models to generate trait-specific quality descriptions. These descriptions serve as external knowledge signals to guide trait-level representation learning, thereby promoting the disentanglement of shared representations. Second, to improve cross-trait collaborative scoring ability in the multi-task learning setting, a mixture-of-experts mechanism that facilitates scoring collaboration is introduced. This approach enables controlled information interaction across traits, effectively leveraging inter-trait correlations while preserving trait independence. Experimental results on public benchmark datasets demonstrate that the proposed method enhances the model's sensitivity to trait-specific feature differences and achieves superior performance over existing approaches in both overall scoring and multiple traits.1) †王炯和吴浩的贡献相同

作文 Dear @ORGANIZATION1, I understand that the idea of advances in technology benefiting society is a very controversal topic. However, I support these advances in technology and I believe that computers have a positive effect on people. They allow friends and family who live far away from each other to communicate and stay in touch. Computers @CAPS7 allow easy access to the news and online textbooks which provides an enourmous amount of benifits to today's society. In the long run, doing more things by computer instead of on paper will save billions of trees! … Computer activities keep our brain excercising and @MONTH1 even help us hit more accurately next baseball season! Three out of five kids at @ORGANIZATION2 say that @CAPS5 they didn't have a computer growing up, they wouldn't be as good at their sport. Computers are an extremely useful recource for many things that we need to take advantages of! LLM生成的不同维度评分依据 [句子流畅度]: The essay demonstrates a mix of fluid and awkward sentence constructions. Some sentences flow naturally, while others are choppy or contain grammatical errors. Variance in sentence structure and length adds interest, but repetitive patterns detract from overall impact.
[单词选择]: The essay demonstrates a limited range of vocabulary, relying on overused expressions and clichés (“beneficial to society, ” “positive effect, ” “extremely useful”). Words are often misused or imprecise, such as “enourmous, ” “benifits, ” and “sace.”
[规范性]: The essay demonstrates limited control of standard writing conventions. It contains frequent spelling errors (e.g., “enourmous, ” “benifits, ” “tremenciously”), incorrect punctuation, and inconsistent capitalization. Grammar and usage errors also impede readability, requiring significant editing.
[组织结构]: The essay is disorganized, lacking clear transitions between ideas. The writer jumps between topics, including personal anecdotes, statistics, and quotes, without a cohesive structure. The text is fragmented, with multiple ideas and quotes presented without logical connections or a clear flow.
[内容]: The essay presents a clear stance on the benefits of computers, citing examples of communication, education, and environmental benefits. However, it relies heavily on personal anecdotes and quotes, lacks depth in analysis, and contains grammatical errors and awkward phrasing, detracting from its overall effectiveness. -
