Construction of Knowledge Map of Power Marketing User Address Data Based on Information Extraction Model

With the rapid development of smart grid, in the power industry, artificial intelligence is rapidly combining with the power grid field, and information and communication technology is rapidly integrated into the power grid production and enterprise management. Information system is the "central nerve" of intelligent grid supporting production and management development. In order to solve the problem of extracting entity knowledge and question and answer system from unstructured data, this paper proposes a method of constructing knowledge map of power marketing user address data based on BERT information extraction model. After the system test, it is proved that the service in the system has high feasibility and stability, and it can face various industries and users with different knowledge levels.
