IIMAS at SemEval-2024 Task 9: A Comparative Approach for Brainteaser Solutions
Cecilia Reyes | Orlando Ramos-flores | Diego Martínez-maqueda
Proceedings of the 18th International Workshop on Semantic Evaluation (SemEval-2024)

In this document, we detail our participation experience in SemEval-2024 Task 9: BRAINTEASER-A Novel Task Defying Common Sense. We tackled this challenge by applying fine-tuning techniques with pre-trained models (BERT and RoBERTa Winogrande), while also augmenting the dataset with the LLMs ChatGPT and Gemini. We achieved an accuracy of 0.93 with our best model, along with an F1 score of 0.87 for the Entailment class, 0.94 for the Contradiction class, and 0.96 for the Neutral class
