基于多模糊约束强模拟的社会群体查询

Social Group Query Based on Multi-fuzzy-constrained Strong Simulation

Guliu Liu, Lei Li, Guanfeng Liu, Xindong Wu

摘要:

传统的社会群体分析大多使用交互模型、事件模型或其他方法来识别和区分群体。这种类型的方法可以基于社交参与者的地理位置、社交关系和/或相关事件将社交参与者划分为不同的组。但在某些应用中,需要对组成员以及组成员之间的交互进行更具体的限制。通常,图模式匹配(GPM)被用来解决这个问题。然而,现有的GPM方法很少考虑节点和边的丰富上下文信息来衡量成员之间的可信度。提出了一种需要考虑群体成员之间信任的社会群体查询问题。针对这一问题,提出了一种基于模式节点拓扑有序序列的强模拟GPM算法(NTSS)。针对NTSS算法在匹配具有多个入度为零的节点的模式图时效率低下以及多个匹配子图共享匹配边的重复计算问题,提出了两种优化策略。最后,在实际应用的四个社交网络数据集上对NTSS算法和优化策略下的算法的有效性和效率进行了验证实验。实验结果表明,NTSS算法的性能明显优于现有的多约束GPM算法,而结合了两种优化策略的NTSS_Inv_EdgC算法大大提高了NTSS算法的效率。

英文摘要:

Traditional social group analysis mostly uses interaction models, event models, or other methods to identify and distinguish groups. This type of method can divide social participants into different groups based on their geographic location, social relationships, and/or related events. However, in some applications, it is necessary to make more specific restrictions on the members and the interaction between members of the group. Generally, graph pattern matching (GPM) is used to solve this problem. However, the existing GPM methods rarely consider the rich contextual information of nodes and edges to measure the credibility between members. In this paper, a social group query problem that needs to consider the trust between members of the group is proposed. To solve this problem, we propose a Strong Simulation GPM algorithm (NTSS) based on the exploration of pattern Node Topological ordered sequence. Aiming at the inefficiency of the NTSS algorithm when matching pattern graph with multiple nodes with zero in-degree and the problem of repeated calculation of matching edges shared by multiple matching subgraphs, two optimization strategies are proposed. Finally, we conduct verification experiments on the effectiveness and efficiency of the NTSS algorithm and the algorithms with the optimization strategies on four social network datasets in real applications. Experimental results show that the NTSS algorithm is significantly better than the existing multi-constrained GPM algorithm, and the NTSS_Inv_EdgC algorithm, which combines two optimization strategies, greatly improves the efficiency of the NTSS algorithm.
