A material source finding method and system

Abstract

This application provides a material sourcing method and system. The method includes: crawling external data; constructing a supply chain knowledge graph based on the external data and internal enterprise data to obtain upstream and downstream relationships; acquiring user tracking data and constructing user behavior sequences based on the user tracking data; inputting the supply chain knowledge graph and user behavior sequences into a supply chain graph and user behavior fusion model for training; constructing and training a dual-tower model of materials and keywords based on historical retrieval data, converting all materials into material vectors; the dual-tower model includes a supply chain graph and user behavior fusion model and a keyword model; inputting keywords into the keyword model to obtain keyword vectors; calculating the similarity between the keyword vectors and all material vectors; and selecting at least one material with the highest similarity as the material sourcing result. This application enables rapid discovery of substitutes and new products in the material database, improving product price transparency and reducing procurement costs and related expenses.
