This project constructs a database, annotates a corpus, and evaluates models for recognizing classical allusions in Chinese texts, supporting humanities research and language education.
L2C-Rater is an automated essay scoring tool that leverages 90 linguistic features and ordinal logistic regression to accurately evaluate Chinese as a second language (L2) essays, providing a robust, interpretable solution for language learners and educators.
This project introduces a model-agnostic diagnostic method using diverse counterfactual interventions to interpret neural-based Automated Essay Scoring models, revealing their decision-making processes and alignment with human scoring rubrics, while offering potential applications across multiple AI domains. 
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.
