推荐系统面临动态适应用户偏好与复杂社交网络中交互关系的挑战。传统方法难以捕捉网络社区内复杂互动,且泛化能力不足。本文提出一种通用型群体智能推荐算法,受社会心理学启发,采用动态超图结构建模用户偏好与社区影响,结合基于中心性的特征提取与Node2Vec嵌入,通过消息传递机制与分层图建模实现偏好演化,支持实时行为适应。实验表明,该算法在社交网络与内容发现任务中表现优异,多个数据集上的命中率(HR)、平均倒数排名(MRR)和归一化折损累计增益(NDCG)均超越基线方法。其对动态环境的适应性使推荐更具上下文相关性与精确性。该框架将个体偏好与群体影响相连接,具备跨领域应用潜力,可用于社交图、个性化学习及医疗图谱等场景。本研究展示了将群体智能与网络动力学结合,应对推荐系统中复杂优化问题的可行性。
原文摘要 · Abstract (English)
Recommendation systems face challenges in dynamically adapting to evolving user preferences and interactions within complex social networks. Traditional approaches often fail to account for the intricate interactions within cyber-social systems and lack the flexibility to generalize across diverse domains, highlighting the need for more adaptive and versatile solutions. In this work, we introduce a general-purpose swarm intelligence algorithm for recommendation systems, designed to adapt seamlessly to varying applications. It was inspired by social psychology principles. The framework models user preferences and community influences within a dynamic hypergraph structure. It leverages centrality-based feature extraction and Node2Vec embeddings. Preference evolution is guided by message-passing mechanisms and hierarchical graph modeling, enabling real-time adaptation to changing behaviors. Experimental evaluations demonstrated the algorithm's superior performance in various recommendation tasks, including social networks and content discovery. Key metrics such as Hit Rate (HR), Mean Reciprocal Rank (MRR), and Normalized Discounted Cumulative Gain (NDCG) consistently outperformed baseline methods across multiple datasets. The model's adaptability to dynamic environments allowed for contextually relevant and precise recommendations. The proposed algorithm represents an advancement in recommendation systems by bridging individual preferences and community influences. Its general-purpose design enables applications in diverse domains, including social graphs, personalized learning, and medical graphs. This work highlights the potential of integrating swarm intelligence with network dynamics to address complex optimization challenges in recommendation systems.
