DAGGER:大型动态图可达性度量的可扩展索引

DAGGER: A Scalable Index for Reachability Queries in Large Dynamic Graphs

Hilmi Yildirim, Vineet Chaoji, Mohammed J. Zaki

摘要:

随着大规模图数据在各种应用领域的普遍存在,有效地查询它们是一个挑战。特别是,可达性查询变得越来越重要,特别是对于包含、包容和连接检查。尽管已经提出了许多方法来实现静态图的可达性,但许多现实世界的图都在不断发展,这就需要动态索引。在本文中,我们提出了一个完全动态的可达性指标的动态图。我们的方法称为DAGGER,是一种基于区间标记的轻量级索引,可扩展到百万节点图及更高。我们对真实世界和合成图进行了广泛的实验评估,证实了其对基线方法的有效性。

英文摘要:

With the ubiquity of large-scale graph data in a variety of application domains, querying them effectively is a challenge. In particular, reachability queries are becoming increasingly important, especially for containment, subsumption, and connectivity checks. Whereas many methods have been proposed for static graph reachability, many real-world graphs are constantly evolving, which calls for dynamic indexing. In this paper, we present a fully dynamic reachability index over dynamic graphs. Our method, called DAGGER, is a light-weight index based on interval labeling, that scales to million node graphs and beyond. Our extensive experimental evaluation on real-world and synthetic graphs confirms its effectiveness over baseline methods.
