  "account": "The article describes the development of an \"Agentic Fraud Investigation System\" using the TigerGraph graph database and 11 specialized AI agents.\n\nThe system connects a suspicious transaction to various entities such as customers, cards, devices, email domains, billing regions and previous fraud cases through relationships stored in a graph database. This allows analysts to explore the broader network of transactions and connections rather than just looking at isolated records.\n\nKey points:\n\n1. The system starts with a suspicious transaction and creates an investigation case. The analyst interacts with it through an AI chat interface to retrieve information, analyze graph relationships and receive recommendations.\n\n2. Traditional fraud analysis looks at individual transactions, but fraud often involves networks of related entities. By modeling these relationships in a graph, the system can identify patterns and evidence that would be missed otherwise. For example, the same device may be used by multiple customers, cards connected to the same device, accounts linked to confirmed fraud cases, etc.\n\n3. The architecture consists of a React UI for presenting the investigation, an agent layer to handle reasoning and task execution, TigerGraph for the graph database and evidence layer, an LLM for the natural language interface, and the agents themselves.\n\n4. The investigation workflow involves creating a case, collecting relevant information, exploring graph relationships, checking previous cases, identifying fraud patterns, evaluating evidence, determining if more evidence is needed, recommending next actions, and saving the investigation result.\n\n5. The 11 AI agents take on specialized roles such as investigation coordinator, graph analysis, transaction analysis, fraud analysis, evidence analysis, case analysis, etc. This multi-agent approach enables a more comprehensive investigation workflow.\n\nIn summary, the article outlines a graph-based approach to fraud investigation that leverages TigerGraph, AI agents, and natural language processing to move beyond simple risk scores and help analysts uncover deeper connections and evidence to guide actionable decisions.",
  "summary": "Fraud investigation is not just about detecting a suspicious transaction. A single transaction can be connected to a customer, card, device, email domain, billing region, previous fraud cases, and many other transactions. Finding these relationships manually can take significant time. For our project, we built an Agentic Fraud Investigation System powered by TigerGraph that combines a graph…",
