Statistical inference on attributed random graphs: Fusion of graph features and content: An experiment on time series of Enron graphs

Fusion of information from graph features and content can provide superior inference for an anomaly detection task, compared to the corresponding content-only or graph featureonly statistics. In this paper, we design and execute an experiment on a time series of attributed graphs extracted from the Enron email corpus which demonstrates the benefit of fusion. The experiment is based on injecting a controlled anomaly into the real data and measuring its detectability. © 2010 Elsevier B.V. All rights reserved.
