Fraud Detection and Visualization for large call graphs

What is it about?

We created CALLMINE, a method to find fraud in a large dataset of phone calls, even in imperfect data settings. CALLMINE is fast and can handle large amounts of data, making it great for both supervised and unsupervised analysis. It's automatic and designed for non-technical audiences. In a real-world test, CALLMINE found fraudsters much faster than human experts – in hours, while it took humans over 10 months.

Why is it important?

Detecting fraud is important because it helps prevent financial losses and ensures the integrity of systems and transactions. The ability to find fraud patterns in phone call data rapidly (7,000 times faster than human experts) can significantly reduce the impact of fraudulent activities, saving time and resources for businesses and organizations. This is important for maintaining the security and trustworthiness of various services and systems, especially when dealing with large-scale datasets and potentially fraudulent behavior.
