A Prompt-Independent and Interpretable Automated Essay Scoring Method for Chinese Second Language Writing
Published in Lecture Notes in Artificial Intelligence, 2021
We propose a method for automated scoring of Chinese L2 essays, specifically HSK test essays, using 90 linguistic features and an Ordinal Logistic Regression model, achieving high accuracy and offering insights for writing feedback. The source code of the project is available at GitHub, and a demo of the project is available at Demo.

Beyond Agreement: Diagnosing the Rationale Alignment of Automated Essay Scoring Methods based on Linguistically-informed Counterfactuals
Published in ACL Anthology: Findings of EMNLP, 2024
We propose a counterfactual intervention method using Large Language Models (LLMs) to reveal that, in automated essay scoring, while BERT-like models focus on sentence-level features, LLMs align more comprehensively with scoring rubrics by emphasizing conventions, accuracy, language complexity, and organization. The source code and data of this paper is available at GitHub.
