摘要:

社区检测对于应用于定向营销和推荐系统等应用至关重要。传统方法依赖于网络结构,而基于嵌入的模型整合了语义信息。然而,当模型利用来自复杂结构如社交网络的局部和全局信息时,会遇到挑战。图神经网络(GNNs)和变换器在捕捉局部和全局关系方面表现出色。在本文中,我们提出了图集成变换器用于社区检测(GIT-CD),一种结合GNN和基于变换器的注意力机制的混合模型,以增强社交网络中的社区检测。具体而言,GNN模块捕捉局部图结构,而变换器模块建模长距离依赖。一个自优化聚类模块利用K-Means、轮廓损失和KL散度最小化来优化社区分配。在基准数据集上的实验结果表明,GIT-CD优于最先进的模型,使其成为在复杂社交网络中检测有意义社区的稳健方法。

英文摘要:

Community detection is crucial for applications like targeted marketing and recommendation systems. Traditional methods rely on network structure, and embedding-based models integrate semantic information. However, there is a challenge when a model leverages local and global information from complex structures like social networks. Graph Neural Networks (GNNs) and Transformers have shown superior performance in capturing local and global relationships. In this paper, We propose Graph Integrated Transformer for Community Detection (GIT-CD), a hybrid model combining GNNs and Transformer-based attention mechanisms to enhance community detection in social networks. Specifically, the GNN module captures local graph structures, while the Transformer module models long-range dependencies. A self-optimizing clustering module refines community assignments using K-Means, silhouette loss, and KL divergence minimization. Experimental results on benchmark datasets show that GIT-CD outperforms state-of-the-art models, making it a robust approach for detecting meaningful communities in complex social networks.
