摘要:

连接强度预测,有时也称为权重预测,对于探索网络中出现的连接模式的多样性至关重要。由于其重要的基础性意义,它在网络分析和挖掘领域引起了广泛的关注。近年来出现的一些相关研究成果极大地推进了我们对如何预测社交网络中的强弱关系的理解。然而,大多数提出的方法都是在很大程度上依赖于一些特殊的上下文,甚至专门用于社交网络的网络感知方法。因此,它们不太适用于各种类型的网络。与以往的研究相比,我们提出了一个新的计算框架,称为邻域估计权重(NEW),它纯粹由网络的基本结构信息驱动,具有适应不同类型网络的灵活性。在NEW中,我们设计了一个新的索引,即,连接倾斜度,以生成网络的代表性特征,其能够捕获联系强度的实际分布。为了获得最优的预测结果,我们还提出了一个参数化的回归模型,近似具有线性的时间复杂度,因此很容易扩展到大规模网络的实现。在六个真实网络上的实验结果表明,我们提出的预测模型优于最先进的方法,这是强大的预测丢失的领带强度时,只有一部分网络的领带强度信息是可用的。

英文摘要:

Tie strength prediction, sometimes named weight prediction, is vital in exploring the diversity of connectivity pattern emerged in networks. Due to the fundamental significance, it has drawn much attention in the field of network analysis and mining. Some related works appeared in recent years have significantly advanced our understanding of how to predict the strong and weak ties in the social networks. However, most of the proposed approaches are scenario-aware methods heavily depending on some special contexts and even exclusively used in social networks. As a result, they are less applicable to various kinds of networks. In contrast to the prior studies, here we propose a new computational framework called Neighborhood Estimating Weight (NEW) which is purely driven by the basic structure information of the network and has the flexibility for adapting to diverse types of networks. In NEW, we design a novel index, i.e., connection inclination, to generate the representative features of the network, which is capable of capturing the actual distribution of the tie strength. In order to obtain the optimized prediction results, we also propose a parameterized regression model which approximately has a linear time complexity and thus is readily extended to the implementation in large-scale networks. The experimental results on six real-world networks demonstrate that our proposed predictive model outperforms the state of the art methods, which is powerful for predicting the missing tie strengths when only a part of the network's tie strength information is available.
