Kensho 使用 LangGraph 建構金融資料多代理框架

🔑 增強重點摘要

• •The Grounding framework utilizes a 'hub-and-spoke' agent architecture where a central orchestrator routes queries to specialized sub-agents responsible for specific S&P Global datasets, such as earnings transcripts or macroeconomic indicators.
• •Kensho implemented a custom human-in-the-loop (HITL) verification layer within LangGraph, allowing financial analysts to validate agent-generated citations against source documents before final output generation.
• •The system addresses the 'hallucination' risk in financial reporting by enforcing strict attribution requirements, where agents must provide direct document links and confidence scores for every data point retrieved.

🛠️ 技術深入

• •Architecture: Implements a directed acyclic graph (DAG) using LangGraph to manage stateful multi-step reasoning chains.
• •Orchestration: Uses a 'Router' agent that classifies user intent and selects the appropriate tool-calling agent based on semantic similarity to available data schemas.
• •Data Integration: Connects to S&P Global's proprietary 'Kensho Knowledge Graph' to perform entity resolution before passing context to the LLM.
• •State Management: Leverages LangGraph's checkpointer to maintain conversation state, enabling long-running, multi-turn analytical sessions without context loss.
