Construction method and device of power field knowledge graph and electronic equipment

The invention provides a construction method and device of a power field knowledge graph and electronic equipment. The method comprises the following steps: obtaining a plurality of entity triads based on a remote supervision method; generating a denoised training set by retaining or not retaining the state of each entity triple through a strategy network, and training a relation extraction model; if the extraction correct rate of the trained relation extraction model is smaller than a preset value, obtaining a feedback value through feedback calculation based on a preset verification set; based on the feedback value, obtaining a state combination enabling the expected feedback value of the policy network to be maximum; taking the annotation data set generated based on the state combination as a denoised annotation data set, and training the relation extraction model until the extraction accuracy of the trained relation extraction model is greater than or equal to a preset value; and extracting the power fiel
