Abstract

The invention discloses a method and a system for constructing an industrial chain knowledge graph. The method comprises the following steps: dividing industrial chain nodes according to industrial chain structure attributes or industrial chain value attributes; determining a relationship between industrial chain nodes based on a production process, a value increment process, technical association and a market supply-demand relationship of products or services in the industrial chain; and constructing an industrial chain knowledge graph according to the divided industrial chain nodes and the relationship between the industrial chain nodes. According to the method, accurate division and relation carding of the industrial chain nodes are realized, the structure and the operation rule of the industrial chain can be understood, a systematized construction process and method are provided, and the construction complexity and cost of the industrial chain graph are reduced.
