Knowledge graph construction method and device for power search questions and answers

The invention discloses a knowledge graph construction method and device oriented to power search questions and answers. The method comprises the steps that plain text, unstructured information and semi-structured information in the power field are collected based on a power system and a power resource network; fuzzy screening is carried out based on the collected power field information, and interference feature data is eliminated; obtaining plain text, unstructured information and semi-structured information after fuzzy screening, and directly converting the plain text and the semi-structured information into a triple; and extracting unstructured information based on a deep neural network model, collecting and storing a triple of the unstructured information, and realizing knowledge graph construction oriented to power search questions and answers. According to the knowledge graph for the power search questions and answers created by the method, radiation divergence is carried out by taking the power distri
