| Resumen |
In this paper, we address the task of Paraphrase Identification in Mexican Spanish (PAR-MEX) at sentence-level. We introduced our method, using text embeddings from pre-trained transformer models for the training process by GAN-BERT, an adversarial learning. We modified noises for the generator, which have a random rate and the same size of the hidden layer of transformers. To improve the model performance, a rule of thumb based on the pair similarity is used to remove possible wrong sentence pairs in positive examples; parallel with the addition of unlabelled data in the same domain. The best obtained F1 is 90.22%, ranked third in the final result table, also outperformed the organizers' baseline. © 2022 Copyright for this paper by its authors.
