Recent multimodal frameworks often grapple with semantic misalignment and noise impeding effective integration of diverse modalities. In order to solve this problem this study presents CaMN (Cross-aligned Multimodal Network) a framework designed to enhance multimodal understanding through a robust cross-alignment mechanism. Unlike conventional fusion methods our framework aligns features extracted from images text and graphs via a tailored loss function enabling seamless integration and exploitation of complementary information. Leveraging Abstract Meaning Representation (AMR) we extract intricate semantic structures from textual data enriching the multimodal representation with contextual depth. Furthermore to enhance robustness we employ a masked autoencoder to simulate noise-independent feature space. Through comprehensive evaluation on the crisisMMD dataset CaMN demonstrates superior performance in crisis event classification tasks highlighting its potential in advancing multimodal understanding across diverse domains.
