Abstract: Systems and methods for computerized fraud detection using machine learning and network analysis are provided. The system includes a fraud detection computer system that executes a machine learning, network detection engine/module for detecting and visualizing insurance fraud using network analysis techniques. The system electronically obtains raw insurance claims data from a data source such as an insurance claims database, resolves entities and events that exist in the raw claims data, and automatically detects and identify relationships between such entities and events using machine learning and network analysis, thereby creating one or more networks for visualization. The networks are then scored, and the entire network visualization, including associated scores, are displayed to the user in a convenient, easy-to-navigate fraud analytics user interface on the user's local computer system.
