Enterprise industry classification method and system based on knowledge graph enhancement

The invention provides an enterprise industry classification method and system based on knowledge graph enhancement. The method comprises the steps of obtaining industry classification related data of an enterprise to be classified and performing corresponding preprocessing; based on the preprocessed industry classification related data, utilizing a pre-trained industry classification model based on deep learning to obtain a classification result of a category to which the enterprise belongs; wherein the industry classification model specifically executes the following processes: performing text splitting on industry classification related data of a to-be-classified enterprise to obtain a short sentence set; adding tags to the sentences in the short sentence set based on a linking result of the sentences in the short sentence set and entities in a pre-constructed knowledge graph; utilizing a pre-trained natural language model to perform feature extraction on the sentences added with the labels; fusing the ext
