Constructing a vertical knowledge graph for non-traditional machining industry

Knowledge graph is powerful tool for knowledge based engineering. In this paper, a vertical knowledge graph is proposed for the non-traditional machining. Firstly, the definition and classification of the knowledge graph are proposed. Then, the construct flow and key techniques are discussed in details for the construction of vertical knowledge graph. Finally, a vertical knowledge graph of EDM (electrical discharge matching) is proposed as a case study to illustrate the feasibility of this method.
