When Argumentation Meets Cohesion: Enhancing Automatic Feedback in Student Writing

AbstractIn this paper, we investigate the role of arguments in the automatic scoring of cohesion in argumentative essays. The feature analysis reveals that in argumentative essays, the lexical cohesion between claims is more important to the overall cohesion, while the evidence is expected to be diverse and divergent. Our results show that combining features related to argument segments and cohesion features improves the performance of the automatic cohesion scoring model trained on a transformer. The cohesion score is also learned more accurately in a multi-task learning process by adding the automatic segmentation of argumentative elements as an auxiliary task. Our findings contribute to both the understanding of cohesion in argumentative writing and the development of automatic feedback.
