Power grid data search method and system based on core data identification and electronic equipment

The embodiment of the invention provides a power grid data searching method and system based on core data recognition and electronic equipment. The method comprises the steps that power grid basic data are collected; performing word segmentation processing on the power grid basic data to obtain a plurality of segmented words; obtaining a service entity in the power grid, performing entity disambiguation on the target dictionary based on the service entity, and obtaining an initial disambiguation result and an initial disambiguation dictionary; identifying the correlation degree of the business entities by adopting the grammar similarity based on the editing distance and the longest common substring and combining the semantic similarity based on the known network and the lexical forest, and optimizing the initial disambiguation dictionary according to the correlation degree of the business entities to obtain an optimized disambiguation dictionary; calculating a final core score of each data item in the optimiz
