Aiming at the problem of fusion and utilization of electric power industry data and external multi-source heterogeneous data

an application idea of internal and external data fusion based on knowledge graph is proposed. Through the analysis of the existing text information extraction and the mainstream technology route of knowledge map construction

an optimized text information extraction scheme and knowledge map construction scheme are proposed to support the modeling work of multi-source heterogeneous data fusion. A pilot application of risk identification in the field of engineering project process management are carried out in a provincial electric power company

which verifies the feasibility of the proposed technical scheme.
