论文摘要

TIE强度预测,有时被称为体重预测,对于探索网络中出现的连接模式的多样性至关重要。由于基本意义,它在网络分析和采矿领域引起了很多关注。近年来,一些相关作品显着提高了我们对如何预测社交网络中牢固和弱关系的理解。但是,大多数提出的方法都是方案感知的方法,具体取决于某些特殊情况,甚至仅在社交网络中使用。结果,它们不太适用于各种网络。 与先前的研究相反,我们在这里提出了一个新的计算框架,称为邻里估计权重(新),该框架纯粹由网络的基本结构信息驱动,并且具有适应各种类型的网络的灵活性。在新的中,我们设计了一个新颖的索引,即连接倾斜度,以生成网络的代表性特征,该特征能够捕获绑带强度的实际分布。为了获得优化的预测结果,我们还提出了一个参数化的回归模型,该模型大约具有线性时间复杂性,因此很容易扩展到大规模网络中的实现。六个现实世界网络上的实验结果表明,我们提出的预测模型的表现优于最先进的方法,这对于仅当网络的TIE强度信息的一部分才能提供时,可以预测缺失的绑带强度。

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.
