Problems solved by technology
Since natural language processing and medical treatment are not closely integrated at present, there are certain defects and deficiencies in the existing technology: First, although the medical records have been formatted as much as possible at the time of input, the format of medical records between different hospitals still exists The format of the old medical records in the past is even more varied, which is not conducive to the further development of medical research; second, there are few technologies for analyzing the relevant information sequence of Chinese medical records, which cannot provide convenience for medical researchers to explore the law of onset

The invention discloses a method for structured analysis and processing of medical record data. The method includes the following steps: preprocessing the original medical record text to obtain diagnosis results and texts without diagnosis results; identifying keywords for texts without diagnosis results; extracting keyword feature vectors, and performing machine learning, spatial visualization and Classification analysis; calculate the degree of correlation between different keywords and diagnosis results according to the analysis results. The method of the present invention can minimize the impact of the difference in the format of the medical records on the analysis, has universal applicability, and can be widely used in the analysis of medical records in various formats; it can classify and analyze the medical records of different departments under the guidance of the training data; It can provide reference for constructing basic information of structured text of medical records and correlation analysis of medical records in the future.
Description
technical field [0001] The invention relates to the technical field of medical record data processing, in particular to a method for structured analysis and processing of medical record data. More specifically, it relates to a method for analyzing and processing medical record data structure based on natural language processing. Background technique [0002] Natural language processing (NLP) is one of the big applications of machine learning in recent years. Its research purpose is to explore how computers understand and use text and speech based on human natural language. The research goal of engaging in natural language processing is to design a machine algorithm similar to human beings through the analysis of the way humans understand language; the second is to use the more popular deep learning tools in recent years to directly analyze natural language texts . [0003] Medical record data contains rich text and numerical information. Now that the trend of electronic ...
