社交网络中的节点分类

Node Classification in Social Networks

Smriti Bhagat, Graham Cormode, S. Muthukrishnan

摘要:

当处理大型图时,诸如在在线社交网络的上下文中出现的那些图,可以标记节点的子集。这些标签可以指示节点(用户)的人口统计值、兴趣、信念或其他特征。一个核心问题是使用这些信息来扩展标签,以便为所有节点分配一个标签(或多个标签)。在这一章中,我们调查分类技术已经提出了这个问题。我们考虑两大类:基于传统分类器的迭代应用的方法,使用图信息作为特征,以及通过随机游走传播现有标签的方法。我们对这些方法采取了一个共同的观点,以突出两个类别内和跨两个类别的不同方法之间的相似性。我们还描述了一些扩展和相关方向的中心问题的节点分类。

英文摘要:

When dealing with large graphs, such as those that arise in the context of online social networks, a subset of nodes may be labeled. These labels can indicate demographic values, interest, beliefs or other characteristics of the nodes (users). A core problem is to use this information to extend the labeling so that all nodes are assigned a label (or labels). In this chapter, we survey classification techniques that have been proposed for this problem. We consider two broad categories: methods based on iterative application of traditional classifiers using graph information as features, and methods which propagate the existing labels via random walks. We adopt a common perspective on these methods to highlight the similarities between different approaches within and across the two categories. We also describe some extensions and related directions to the central problem of node classification.
