NEU-ESC: A Comprehensive Vietnamese dataset for Educational Sentiment analysis and topic Classification toward multitask learning
This addresses the problem of limited resources for educational sentiment analysis in Vietnamese, though it is incremental as it builds on existing multitask learning methods.
The authors tackled the lack of domain-relevant Vietnamese educational datasets by introducing NEU-ESC, a dataset from university forums, and achieved up to 83.7% and 79.8% accuracy for sentiment and topic classification using multitask learning with BERT models.
In the field of education, understanding students' opinions through their comments is crucial, especially in the Vietnamese language, where resources remain limited. Existing educational datasets often lack domain relevance and student slang. To address these gaps, we introduce NEU-ESC, a new Vietnamese dataset for Educational Sentiment Classification and Topic Classification, curated from university forums, which offers more samples, richer class diversity, longer texts, and broader vocabulary. In addition, we explore multitask learning using encoder-only language models (BERT), in which we showed that it achieves performance up to 83.7% and 79.8% accuracy for sentiment and topic classification tasks. We also benchmark our dataset and model with other datasets and models, including Large Language Models, and discuss these benchmarks.
