Fact-data engineering + knowledge base
An AI-Driven Data Foundation
Facing e-commerce statements in wildly different formats from JD, Douyin, Alipay, Amazon and more, the platform normalizes heterogeneous statements into a standard fact layer with Decimal(20,4) precision using sandboxed JS parsing scripts, then distills platform rules, accounting items and script samples into a reasoning-ready business knowledge base through pgvector + HNSW vector indexing and hybrid retrieval (vector + keyword → RRF → MMR). AI finally 'reads' e-commerce finance instead of staring at piles of Excel files.
