The invention provides an official document abstract generation model combining an extraction type and a generation type. The extraction type abstract and the generation type abstract are combined andofficial document data is screened and pre-processed. Meanwhile, the semantic meaning of weak label data generated by the extraction type abstract is enhanced. An official document text abstract automatic generation model is learned to realize automatic generation of the official document abstract. Compared with a traditional abstract generation method based on end-to-end and adding an attentionmechanism, the method has the advantages that the problem of lack of training data is solved, data screening and semantic enhancement are carried out on the basis of the characteristics of the official document data, and the semantic meaning of the official document text can be represented more accurately.
