The invention relates to a resume information extraction method and system. The resume information extraction method comprises the steps: A, obtaining resume data; B, converting the resume data into resume texts by utilizing a BERT Chinese pre-training model and a data augmentation technology, and classifying the resume texts according to sentence characteristics of the resume texts; C, conductingnamed entity recognition on the classified resume text sentences through a BERT + BiGRU + CNN + CRF model, and then extracting needed information elements; and D, storing the extracted information elements in a database, and outputting corresponding information in a structured manner. The resume information extraction system is mainly composed of a resume acquisition module, an input module, a classification module, an information element extraction module, a storage module and an output module. The resume information extraction method uses an incremental learning method, and uses a clause mode in data preprocessing of the classification model, so that the language model can adjust parameters by incrementally inputting new training data on the basis of inheriting past parameters, and theresume information extraction method has better continuity and generalization ability.
