Abstract

Fraud in mobile telecommunications is a complex and dynamic problem for Telecom operators. These companies have developed and are exploring new ways of making the fraud detection process more efficient. Most of these attempts are based in fraud management systems, capable of detecting fraudulent communications. In this paper, we present a case-based reasoning system that aids fraud analysts in the classification of potential fraud cases. The system developed, presents to the analyst the most similar past cases, representing suspicious communication episodes that were previously investigated. We also describe an example of how the system is used.
