To alleviate these challenges, we propose Bi-Graph Attention Network for Event Detection (BiGAT-ED), integrating syntactic and semantic features through a multi-perspective graph architecture. Specifically, we propose the Edge-Enhanced Graph Attention Network (EE-GAT) to incorporate syntactic dependency information into the attention mechanism, reducing the impact of redundant connections. We further construct the Event Relation Graph (ERG) to model inter-event connections and encode it with the Node-Aware Graph Attention Network (NA-GAT), which leverages event label knowledge within its attention mechanism for enhanced semantic correlation modeling. Finally, BiGAT-ED integrates event correlations from EE-GAT and NA-GAT through an attention fusion mechanism, improving performance for multiple event identification.

Besides, although large language model has been applied to VMR, it still suffers from sophisticated prompt design and multi-turn question answering, which is far from being automated. To address these issues, we propose AutoVMR, a novel multimodal large language model framework that employs an autonomous event generation and localization approach for VMR. AutoVMR utilizes an autoregressive architecture, accepting video input and a fixed prompt template, to generate event descriptions of video segments along with their corresponding start and end times. We also introduce a reward model based on Intersection over Union (IoU), trained using reinforcement learning from human feedback. This model is integrated into the Proximal Policy Optimization (PPO) training strategy and includes a query-time boundary generation mechanism to improve AutoVMR's performance. The reward model's modeling approach effectively filters out noise in the VMR dataset, enabling the PPO method to better comprehend video content and generate more accurate temporal localizations. Moreover, the integration of the autoregressive process with PPO training allows the model to be trained on unannotated video data, leading to improved performance in a semi-supervised setting.

To address this issue, this paper proposes a group consensus optimization model driven by a rational incentive mechanism, integrating trust attenuation propagation with optimal trust path selection. First, an inverse dynamic programming model with trust amplitude is developed to explore the optimal propagation path of trust relationships between decision makers. Second, a distributed linguistic trust propagation operator considering trust attenuation (impacts of path length and decision makers' positions in the trust chain) is constructed to analyze the dynamic changes of trust relationships during propagation. Furthermore, a dynamic incentive feedback model based on rational adjustment is established, followed by a minimum adjustment optimization model driven by the rational incentive mechanism. The key innovation of the model lies in: enhancing decision makers' willingness to adjust opinions proactively through incentives (avoiding resistance from forced adjustment) and constraining rational adjustment within a maximum tolerance range (mitigating divergence caused by trust transmission risks).
