Abstract: A named entity recognition method for medical texts based on a pre-training model and fine tuning technology. A BERT pre-training model is firstly pre-trained using medical texts such as large-scale unstructured electronic medical records and the like so as to obtain a pre-training model containing semantic representation information in the texts. The generated pre-training model is subjected to fine turning by a stack extension convolutional neural network so as to obtain a deep neural network model capable of carrying out automatic named entity recognition in the medical field. The pre-training model provided in the method can capture semantic information in the texts more accurately and can migrate the semantic information to a specific task more effectively, thus improving the accuracy of named entity recognition. The method combines the stack expansion convolutional neural network and the pre-training model for fine tuning of the model used for final named entity recognition of medical texts, thereby not only excellently capturing semantic information in the texts but also enabling parallel computing for improved model training speed.
