Featured NodeXL Paper
Graph Analysis for Detecting Fraud, Waste, and Abuse in Healthcare Data
Featured paper
Dr. Juan Liu and colleagues from Palo Alto Research Center use NodeXL as a graph analysis tool to detect suspicious activities in healthcare networks.

Detection of fraud, waste, and abuse (FWA) is an important yet difficult problem. In this paper, we describe a system to detect suspicious activities in large healthcare claims datasets. Each healthcare dataset is viewed as a heterogeneous network of patients, doctors, pharmacies, and other entities. These networks can be large, with millions of patients, hundreds of thousands of doctors, and tens of thousands of pharmacies, for example. Graph analysis techniques are developed to find suspicious individuals, suspicious relationships between individuals, unusual changes over time, unusual geospatial dispersion, and anomalous networks within the overall graph structure. The system has been deployed on multiple sites and data sets, both government and commercial, to facilitate the work of FWA investigation analysts.
