Production system
A multi-host RAG platform serving ECB and NCB experts across Eurosystem frameworks. Each bot is configured against its own combination of frameworks. Piloted on collateral eligibility.
- Frameworks standardised via a custom ECB ontology built on ELI and FIBO, developed with subject-matter experts, then compiled into a knowledge graph on Apache AGE (EC2). Retrieval spans BM25 through graph traversal, with queries augmented and normalised against the ontology.
- Ports-and-adapters architecture with the compiled LangGraph agent cached on TTL.
- Short- and long-term memory feeds conversations back as durable facts about ECB frameworks.
