物料价格多源数据结构化与时空检索方法及系统
By tracing the generation dependencies of price records, identifying path types, and performing reverse stripping or targeted correction, a target comparison caliber price is generated, solving the problem of converting multi-source prices to the same comparison caliber and improving the comparability and consistency of price retrieval.

AI Technical Summary
Existing technologies struggle to reliably convert the prices of multi-source materials from different production chains into the same comparative caliber without disrupting the original price formation logic, leading to distorted price comparability search results.
By tracing the upstream generation dependencies of price records, the price formation path type is identified, and reverse stripping or targeted correction is performed on price records with reversible transformation conditions to generate target comparison prices. Combining the price formation path type and upstream generation dependencies, reversible transformation is determined, basic price information is constructed, and spatiotemporal joint retrieval is performed based on constraint rules to output a set of comparable price results.
This approach improves the reuse efficiency and retrieval consistency of multi-source price data while ensuring price comparability, reduces system maintenance complexity, and enhances the adaptability of price retrieval results.
