社会影响力的实证评价

An Empirical Evaluation Of Social Influence Metrics

Nikhil Kumar, Ruocheng Guo, Ashkan Aleali, Paulo Shakarian

摘要:

预测个人何时会采取新的行为是营销和公共卫生等应用领域的一个重要问题。本文研究了各种各样的社会网络的测量文献中提出的性能-这是以前没有直接比较。我们研究了个体受影响的概率,这些概率是基于来自邻居(即影响者数量、个人网络暴露)、结构多样性、地点、时间测量、级联测量和元数据的测量。我们还研究了基于分类器的选择预测影响力的能力,以及训练和测试中阳性样本与阴性样本的比例如何影响预测结果-进一步使这些概念在社会影响力应用中的实际应用成为可能。

英文摘要:

Predicting when an individual will adopt a new behavior is an important problem in application domains such as marketing and public health. This paper examines the perfor- mance of a wide variety of social network based measurements proposed in the literature - which have not been previously compared directly. We study the probability of an individual becoming influenced based on measurements derived from neigh- borhood (i.e. number of influencers, personal network exposure), structural diversity, locality, temporal measures, cascade mea- sures, and metadata. We also examine the ability to predict influence based on choice of classifier and how the ratio of positive to negative samples in both training and testing affect prediction results - further enabling practical use of these concepts for social influence applications.
