Multi-modal Semantic Understanding with Contrastive Cross-modal Feature Alignment

Multi-modal semantic understanding requires integrating information from different modalities to extract users' real intention behind words. Most previous work applies a dual-encoder structure to separately encode image and text, but fails to learn cross-modal feature alignment, making it hard to achieve cross-modal deep information interaction. This paper proposes a novel CLIP-guided contrastive-learning-based architecture to perform multi-modal feature alignment, which projects the features derived from different modalities into a unified deep space. On multi-modal sarcasm detection (MMSD) and multi-modal sentiment analysis (MMSA) tasks, the experimental results show that our proposed model significantly outperforms several baselines, and our feature alignment strategy brings obvious performance gain over models with different aggregating methods and models even enriched with knowledge. More importantly, our model is simple to implement without using task-specific external knowledge, and thus can easily migrate to other multi-modal tasks.

Research on the Stability Structuring of Cooperation and Conflicts between main manufacturers and suppliers of the large airctaft project——analysis based on the game payoff structure matrix

The large aircraft project of China adopted the “main manufacturers – suppliers” mode for research and development (R&D), and the conflict that existed in the process of cooperation between the two sides will affect the results of the large aircraft project. This paper analyzed the cooperation and conflict between the main manufacturers and suppliers from the perspective of the expected return. Through the establishment of the game payoff structure matrix, the factors which affected the stable operation of the "main manufacturers – suppliers "mode were researched. Keywords: the main manufacturers; suppliers; cooperation and conflict; payoff matri
