Hierarchical Cross-Modal Attention Network for Multimodal Sentiment Analysis
This research introduces the Hierarchical Cross-Modal Attention Network (HCMA) to enhance multimodal sentiment analysis. It addresses key challenges such as insufficient exploitation of textual syntactic features, coarse-grained cross-modal alignment, and the balance between global and local information. By integrating CoreNLP parsing, a BiAffine attention mechanism for fine-grained textual dependency graphs, and a novel hierarchical cross-modal attention mechanism with syntactic guidance, HCMA achieves superior performance in both classification and regression tasks on CMU-MOSI and CMU-MOSEI datasets. The model's design ensures a lightweight yet effective approach for capturing inter-modal associations and preserving global context.

Enhanced Cross-Modal Interaction
A core innovation of HCMA is its ability to build a syntactic guidance matrix. This mechanism quantifies the association strength between textual words (especially attribute words) and visual objects, leveraging CoreNLP and BiAffine to refine dependency parsing. This ensures that entity nouns are precisely linked to relevant visual objects, mitigating attention dilution and improving the accuracy of cross-modal alignment. For instance, when analyzing a product review, the system accurately associates descriptive adjectives in the text with specific product features in the image, leading to a more nuanced sentiment understanding.
