论文摘要
在线社交网络已成为传播最新政治,商业和社会信息的关键媒介。通常会选择高知名度的用户作为种子传播信息并影响其在目标群体中的采用。我们研究性别差异和相似性如何影响信息传播过程。使用大规模的Instagram数据集和一个小规模的Facebook数据集,我们首先进行了多方面的分析,考虑了交互类型,方向性和频率。为此,我们探索了各种现有和新的单一和多台阶性措施。我们的分析揭示了男性和女性根据相互作用类型(例如,喜欢或评论)的相互作用不同的相互作用,并且它们具有不同的支持和促进模式。我们补充了先前的工作,表明女性在连通性和相互作用强度上共同考虑了女性的最高可见性(通常称为玻璃天花板效应),这两者以前主要是独立讨论的。 受这些观察的启发,我们提出了一个新型的播种框架,称为差异播种,旨在在达到目标用户群体的同时最大程度地增加差异,例如某些百分比的女性 - 促进了代表性不足的群体的影响。差异种子通过两种性别感知的措施,目标HI-INDEX和嵌入指数对有影响力的用户进行排名。比较差异播种与目标敏锐性算法的广泛模拟表明,差异播种符合目标百分比,同时有效地最大程度地提高了扩散。差异种子可以推广以应对不同类型的不平等,例如种族,并主动促进社会中的少数群体。
Online social networks have become a crucial medium to disseminate the latest political, commercial, and social information. Users with high visibility are often selected as seeds to spread information and affect their adoption in target groups. We study how gender differences and similarities can impact the information spreading process. Using a large-scale Instagram dataset and a small-scale Facebook dataset, we first conduct a multi-faceted analysis taking the interaction type, directionality and frequency into account. To this end, we explore a variety of existing and new single and multihop centrality measures. Our analysis unveils that males and females interact differently depending on the interaction types, e.g., likes or comments, and they feature different support and promotion patterns. We complement prior work showing that females do not reach top visibility (often referred to as the glass ceiling effect) jointly factoring in the connectivity and interaction intensity, both of which were previously mainly discussed independently. Inspired by these observations, we propose a novel seeding framework, called Disparity Seeding, which aims at maximizing spread while reaching a target user group, e.g., a certain percentage of females -- promoting the influence of under-represented groups. Disparity Seeding ranks influential users with two gender-aware measures, the Target HI-index and the Embedding index. Extensive simulations comparing Disparity Seeding with target-agnostic algorithms show that Disparity Seeding meets the target percentage while effectively maximizing the spread. Disparity Seeding can be generalized to counter different types of inequality, e.g., race, and proactively promote minorities in the society.
