发现时间社会网络中的关键节点

Discovering Key Nodes in a Temporal Social Network

Jinshuo Liu, Chenghao Mou, Donghong Ji

摘要:

[背景]发现关键节点在社会网络分析(SNA)中具有重要意义。对关键节点的有效、准确挖掘,促进了广告、推荐等领域的成功应用。【方法】针对用户行为的时间属性和类别属性--何时转发或回复消息,以及通过结构嵌入度量的社交亲密度,设计了一种更敏感的PageRank类算法,以适应不断增长和变化的社交网络,挖掘关键节点。【结果】与基线PageRank算法相比,在SNAP Higgs数据集的SIR疾病模拟中,该算法选择的关键节点表现明显更好。[结论]这些结果有助于更好地理解社会事件在网络上的传播。

英文摘要:

[Background]Discovering key nodes plays a significant role in Social Network Analysis(SNA). Effective and accurate mining of key nodes promotes more successful applications in fields like advertisement and recommendation. [Methods] With focus on the temporal and categorical property of users' actions - when did they re-tweet or reply a message, as well as their social intimacy measured by structural embeddings, we designed a more sensitive PageRank-like algorithm to accommodate the growing and changing social network in the pursue of mining key nodes. [Results] Compared with our baseline PageRank algorithm, key nodes selected by our ranking algorithm noticeably perform better in the SIR disease simulations with SNAP Higgs dataset. [Conclusion] These results contributed to a better understanding of disseminations of social events over the network.
