Abstract

The embodiment of the invention belongs to the field of artificial intelligence, is applied to the field of intelligent medical treatment, and relates to a medical entity extraction method based on vocabulary enhancement. The method comprises the following steps of: performing multi-granularity word segmentation processing on training corpus data, sequentially inputting segmented words into a word vector module to obtain an initial word vector, marking training corpus data according to the constructed word query dictionary to obtain a marked corpus, training the initial medical entity extraction model by using an enhanced word vector obtained by splicing the marked corpus and the initial word vector to obtain an intermediate medical entity extraction model, evaluating the intermediate medical entity extraction model to obtain an initial medical entity extraction model, determining a final medical entity extraction model according to the evaluation result, and inputting the test corpus data into the medical entity extraction model to obtain a medical entity extraction result. The invention further provides a medical entity extraction device and equipment based on vocabulary enhancement and a medium. In addition, the invention also relates to a block chain technology, and the word query dictionary can be stored in a block chain. According to the invention, the accuracy of medical entity recognition and extraction is improved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence and digital medical technology, and in particular to a method, device, equipment and medium for medical entity extraction based on vocabulary enhancement. Background technique [0002] With the development of medical products, people's demand for medical insurance has also increased, and with it, a large number of fraudulent insurance behaviors have occurred. The National Medical Insurance Bureau requires the Medical Insurance Bureau to increase its crackdown on fraudulent insurance behaviors and consolidate the high-pressure situation. The medical insurance department uses intelligent means to investigate and deal with different scenarios, which requires the establishment of indicator systems of different dimensions from the perspective of big data to accurately locate risks. To establish a complete indicator system, it is necessary to analyze the characteristics of dif...
