Improving Academic Skills Assessment with NLP and Ensemble Learning
It addresses the problem of timely and comprehensive feedback on cognitive and linguistic skills for educational applications, though it appears incremental as it combines existing methods.
This study tackled the challenge of assessing foundational academic skills by integrating multiple NLP models like BERT and RoBERTa into an ensemble framework, resulting in improved accuracy and efficiency compared to traditional methods.
This study addresses the critical challenges of assessing foundational academic skills by leveraging advancements in natural language processing (NLP). Traditional assessment methods often struggle to provide timely and comprehensive feedback on key cognitive and linguistic aspects, such as coherence, syntax, and analytical reasoning. Our approach integrates multiple state-of-the-art NLP models, including BERT, RoBERTa, BART, DeBERTa, and T5, within an ensemble learning framework. These models are combined through stacking techniques using LightGBM and Ridge regression to enhance predictive accuracy. The methodology involves detailed data preprocessing, feature extraction, and pseudo-label learning to optimize model performance. By incorporating sophisticated NLP techniques and ensemble learning, this study significantly improves the accuracy and efficiency of assessments, offering a robust solution that surpasses traditional methods and opens new avenues for educational technology research focused on enhancing core academic competencies.
