MSAD-Moroccan dialect: a multimodal sentiment analysis dataset for Moroccan dialect (Darija)

Sentiment analysis for Arabic dialects remains a significant challenge, mainly due to the scarcity of annotated resources and the inherently multimodal nature of real-world human communication. Among Arabic dialects, Moroccan Darija is particularly underrepresented in the literature, as most existing datasets focus exc...

Focal-Loss Transformer with Feedback-Validation Learning for Imbalanced Drug Interaction Extraction

Drug-drug interactions (DDIs) are a leading cause of preventable adverse drug events, and the standard benchmark corpus for extracting them from biomedical text is severely im-balanced towards non-interacting pairs, making rare interaction types hard to learn. We asked whether combining focal loss, entity-aware transfo...
