| Challenge: | EWS financial flows are opaque and lack standardized labels, structures, and terminology for EWS-related spending. |
| Approach: | They propose an agent-based Retrieval-Augmented Generation system that uses hybrid retrieval and internal chain-of-thought reasoning to extract relevant financial data and classify EWS investments. |
| Outcome: | The proposed system outperforms four alternatives on multi-label classification and budget allocation on an annotated CREWS Fund corpus. |
