Local clustering in these graphs, in which we start with a seed vertex and grow a cluster around it, is of paramount importance because it supports critical provenance applications such as identifying semantically meaningful tasks in an object's history. However, generic graph clustering algorithms are not effective at these tasks. We identify three key properties of provenance graphs and exploit them to justify two new centrality metrics we developed for use in performing local clustering on provenance graphs.en-USConference Paper2014-01-14Macko, Peter; Margo, Daniel Wyatt; Seltzer, Margo I.2017-09-2010.1145/2505515.2505624
