摘要:

我们如何在大规模的图形会计数据集中发现洗钱?如何在时间演化的会计图表中识别最可疑的时期?在时间限制下,从业者应该优先考虑哪些类型的帐户和事件?为了解决会计和审计任务中的这些关键挑战,我们提出了一个灵活的系统,称为AutoAudit,这对审计师和风险管理专业人员来说是有价值的。综上所述,所提出的系统有四个主要优点:(a)“Smurfing”检测,在真实世界的数据集中自动发现近100%的注入洗钱交易。(b)Attention Routing,关注时间演化图中最可疑的部分,并提供直观的解释。(c)洞察发现,确定类似的月对模式证明了“成功的故事”和模式遵循幂律对数逻辑尺度。(d)可扩展性和通用性,确保AutoAudit线性扩展,并可以轻松扩展到其他真实世界的图形数据集。在各种真实数据集上的实验表明了该方法的有效性。为了促进可重复性和可访问性,我们在https://github.com/mengchillee/AutoAudit上公开了代码、图和结果。

英文摘要:

How can we spot money laundering in large-scale graph-like accounting datasets? How to identify the most suspicious period in a time-evolving accounting graph? What kind of accounts and events should practitioners prioritize under time constraints? To tackle these crucial challenges in accounting and auditing tasks, we propose a flexible system called AutoAudit, which can be valuable for auditors and risk management professionals. To sum up, there are four major advantages of the proposed system: (a) "Smurfing" Detection, spots nearly 100% of injected money laundering transactions automatically in real-world datasets. (b) Attention Routing, attends to the most suspicious part of time-evolving graphs and provides an intuitive interpretation. (c) Insight Discovery, identifies similar month-pair patterns proved by "success stories" and patterns following Power Laws in log-logistic scales. (d) Scalability and Generality, ensures AutoAudit scales linearly and can be easily extended to other real-world graph datasets. Experiments on various real-world datasets illustrate the effectiveness of our method. To facilitate reproducibility and accessibility, we make the code, figure, and results public at https://github.com/mengchillee/AutoAudit.
