Use of Graphs in Analyzing Insurance Fraud
Graphs and networks play a crucial role in analyzing and detecting insurance fraud by allowing for complex relationships between claims and involved parties to be visualized. A prominent example discussed is the simulation created by Bavo, which uses political donation data to mimic fraud detection methods. By projecting networks from donation data such as identifying connections between PACs that received contributions from the same donor, insights can be generated about potential fraudulent activity. This method highlights how analyzing social structures can uncover anomalies and lead to the identification of suspicious claims.
