Abstract

The invention belongs to the technical field of Chinese medical named entity identification, and provides a Chinese medical named entity identification method and system, a storage medium and equipment. The Chinese medical named entity recognition method comprises the steps of obtaining clinical text data; converting the clinical text data into a character embedding representation, a medical concept embedding feature vector and a cross-language Chinese embedding representation of a medical text respectively, and splicing the character embedding representation, the medical concept embedding feature vector and the cross-language Chinese embedding representation to obtain a multivariate data fusion feature vector; inputting the multivariate data fusion feature vector into a named entity recognition model based on multiple graphs, and recognizing a Chinese medical named entity type, wherein the named entity recognition model based on multiple graphs comprises a multi-graph network and an LSTM-CRF model, the multi-graph network is used for receiving a text graph formed by taking a multivariate data fusion feature vector as a node, outputting a final state of the node and transmitting the final state to the LSTM-CRF model, and the LSTM-CRF model outputs a recognition result. The Chinese medical named entity identification accuracy is improved.

Description

technical field

[0001] The invention belongs to the technical field of Chinese medical named entity recognition, and in particular relates to a Chinese medical named entity recognition method, system, storage medium and equipment. Background technique

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Named entity recognition refers to the recognition of entities with specific meanings in free text, such as names of people, places, proper nouns, etc. Medical named entity recognition identifies entities such as diseases, symptoms, treatments, etc. from physicians' treatment records. Medical named entity recognition is the basis and key to the semantic structuring of electronic medical records. Its task is to identify different entities from the medical text of electronic medical records, such as diseases, symptoms, treatments, drugs, operations, and analytical si...
