dc.description.abstractThis study introduces a novel method that merges propagation-based transfer learning with word embeddings for rumor detection. This approach aims to utilize data from languages with abundant resources to enhance performance in languages with limited availability of annotated corpora in this task. Furthermore, we augment our rumor detection framework with two supplementary tasks -stance classification and bot detection- to reinforce the primary task of rumor detection. Utilizing our proposed multi-task system, we generate several pretrained models that are subsequently fine-tuned for rumor detection in English. The results indicate significant improvements over baselines, thereby empirically validating the efficacy of our proposed approach. Although a direct metric comparison is difficult, given the different datasets and techniques used in the state-of-the-art, we compare our proposal with 20 other works that target rumor detection in English. By combining stance classification and bot detection as auxiliary tasks, we achieve a Macro-F1 of 0.914. On the other hand, we achieve a Macro-F1 of 0.804 for the Spanish language. In both cases, we beat baseline results, evidencing the proposed approach's usefulness
