| # PROPOR FOS Classification Dataset | |
| Dataset utilized in the paper "Field of Science and Technology Classification of Academic Documents in Portuguese". | |
| Contains 9,696 examples of Portuguese academic thesis, split between two distinct files: | |
| - "train.csv": Used to fine-tune encoder-based models (7,756 samples) | |
| - "test.csv": Used to evaluate fine-tuned models and zero-shot decoder-based models (1,940 samples) | |

| abstract = "Towards improving metadata in academic repositories, this study evaluates the efficacy of different transformer-based models in the automatic classification of the Field of Science and Technology (FOS) of academic theses written in Portuguese. We compare the performance of four different encoder models, two multilingual and two Portuguese-specific, against five larger decoder-based LLMs, on a dataset of 9,696 theses characterized by their title, keywords, and abstract. Fine-tuned encoder-based models achieved the best scores (F1 = 88{\%}), outperforming general-purpose decoder models prompted for the task. These results suggest that, for localized academic domains, task-specific fine-tuning remains more effective than general-purpose LLM prompting." | |
