Ontology-Based Knowledge Graph Construction and Application for Large Workpiece Forging

Due to the advent of the big data era and the redundancy of industrial data, people use a series of information technologies to continuously promote the transformation of traditional industry, and the development of industry is bound to move into the era of intelligence. The article carries out the construction of process knowledge mapping on the existing industrial process design scheme, constructs a process ontology model through industrial specifications, starts from acquiring data from industrial archives, identification of industrial entities, extraction of relationships between industrial entities and fusion of process knowledge, and constructs a process assembly knowledge mapping in the forging field by storing the acquired process data into the graph database, and finally The visualization display of data storage based on database Neo4j is realized. The experimental results have verified the feasibility of the designed diagram.
