AI-Driven Sensing for Cross-Lingual Risk Prediction via Semantic Alignment and Multimodal Temporal Fusion

In the context of highly interconnected global markets and the rapid dissemination of multilingual information, traditional risk prediction methods that rely on single numerical sequences or monolingual text are insufficient for achieving early perception of cross-market risks. To address this issue, a cross-market risk early warning framework based on multilingual large language models and multimodal sensing fusion is proposed. The proposed approach is centered on a unified risk semantic space, where cross-lingual semantic alignment is employed to reduce semantic discrepancies across languages. Furthermore, a semantic–volatility coupling attention mechanism is introduced to capture the dynamic relationship between textual semantic evolution and market fluctuations. In addition, cross-market knowledge transfer and low-resource enhancement strategies are incorporated to improve the model’s generalization capability across multilingual and multi-market environments, thereby establishing an intelligent perception and early warning system for complex sensing scenarios. Experimental results demonstrate that the proposed method significantly outperforms multiple baseline models in multilingual cross-market risk prediction tasks. In the main experiment, the model achieves a root mean squared error (RMSE) of 0.1127, an mean absolute error (MAE) of 0.0846, and an area under the curve (AUC) of 0.8879, while the early warning gain is improved to 5.2 days, which is substantially better than the Transformer model (RMSE 0.1365, AUC 0.8042) and the multilingual BERT-based fusion model (AUC 0.8395). In terms of classification performance, higher accuracy, precision, and recall are consistently achieved, with overall accuracy exceeding 0.88, and both precision and recall are maintained above 0.85, indicating strong discriminative capability in risk identification tasks. Cross-lingual generalization experiments further verify the robustness of the proposed framework. When trained solely on the English market, the model achieves AUC values of 0.8624 and 0.8471 on the Chinese and European markets, respectively, with RMSE reduced to 0.1185, significantly outperforming competing methods. Overall, the proposed approach achieves substantial improvements in prediction accuracy, cross-lingual generalization, and early warning performance, providing an effective solution for artificial intelligence-driven sensing and risk early warning.
