Description

A kind of clinical data group classification method based on Chinese medical main suit's analysis
Technical field
It is the present invention relates to machine learning algorithm and data mining technology field, in particular to a kind of based on the medical main suit of Chinese The clinical data group classification method of analysis.
Background technique
The different brackets of different hospital, hospital, the level of informatization is irregular in institute, in the not high doctor of the level of informatization Inside institute, each operation system is there are data silo, in institute between each system, between Hospitals in Region and hospital, and hospital and society Can there be different degrees of data barrier between the public.
With the continuous development of big data technology, under the dual promotion of policy and technology, hospital has strong wish to disappear Except internal data barrier, miniature, small hospital's clinical data center is established, to the interconnecting of data, the scientific research of doctor needs It asks, the Diseases diagnosis in institute, reduce doctor's misdiagnosis rate etc. and will have important meaning.
Doctor needs the auxiliary of many relevant informations in diagnosis and treatment process, and most important information source is the various of patient Clinical examination checks the data group of data composition.These examine detection datas composition data group, be imported into disease database it Afterwards, it is capable of forming the support of disease aid decision, guidance is further formed to the work of doctor, so that accurate judgement disease, provides Diagnosis and treatment scheme reduces technical fault.Therefore, if data model can be established, data composition is checked to various clinical examinations Data group carries out analysis mining, realizes the exact classification to data group, it will the working efficiency for greatly improving doctor, to building institute Interior small-sized, miniature clinical data center is of great significance.
Based on the above situation, the invention proposes a kind of clinical data group classification sides based on Chinese medical main suit's analysis Method.
Summary of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides it is a kind of be simple and efficient analyzed based on Chinese medical main suit Clinical data group classification method.
The present invention is achieved through the following technical solutions:
A kind of clinical data group classification method based on Chinese medical main suit's analysis, it is characterised in that: the following steps are included:
The first step is formed using main suit of the machine learning algorithm to various clinical examinations inspection data and doctor's typing Data group carries out analysis mining, obtains information and knowledge that data group implies;
Second step, the data source provided according to hospital information system carry out at analysis the main suit content of doctor's typing Reason obtains the data classification of data group in conjunction with information and knowledge that the data group got implies;
Third step, by the corresponding data category in data group deposit clinical data center relevant knowledge library.
In the first step, it is described using machine learning algorithm to various clinical examinations check data composition data group into Row analysis mining, including Chinese text pretreatment, feature extraction, data modeling and Knowledge Discovery.
The Chinese text pretreatment includes text data cleaning, word segmentation and data mapping.
The data cleansing refers to processing missing data and exceptional value, and weeds out unrelated with data modeling in initial data Data.
The word segmentation, which refers to, checks that data and doctor are recorded for various clinical examinations using the customized dictionary for word segmentation of user The main suit entered segments respectively;The customized dictionary for word segmentation of user uses main suit's relevant medical dictionary, and cuts in word Timesharing load uses.
The data mapping refers to building inspection and data classification Standard Map table, and using Standard Map table respectively to each Kind clinical examination checks that the main suit of data and doctor's typing is standardized.Example: hypertension three-level (XXX) is mapped as height Blood pressure three-level.
The feature extraction includes following two parts:
First, load user's Custom Dictionaries segment the main suit content of doctor's typing, after being converted to term vector After extracting main suit's Feature Words, code conversion is carried out to main suit's Feature Words;
Second, data, which carry out cutting, to be checked to various clinical examinations using additional character, filters out the character without Chinese , and data, which are standardized, to be checked to various clinical examinations respectively using Standard Map table;Then load user makes by oneself Various clinical examinations after standardization are checked that data segment by adopted dictionary, extract clinical examination after being converted to term vector It checks data characteristics word, data characteristics word, which carries out code conversion, then to be checked to clinical examination.
The data modeling refer to the main suit's content and various clinical examinations that have carried out code conversion check data into Row modeling;After data modeling, it is original set that the result of data model output, which is carried out code conversion again, to construct main suit Content, various clinical examinations check the regulation engine between data and data classification.
In the third step, the corresponding data category in the clinical data center relevant knowledge library includes disease category and inspection Look into classification.
The beneficial effects of the present invention are: should be based on the clinical data group classification method of Chinese medical main suit's analysis, by making Data model is established with machine learning related algorithm, the main suit composition of data and doctor's typing is checked to various clinical examinations Data group carries out analysis mining, realizes the exact classification to data group, can not only greatly improve the working efficiency of doctor, also It is of great significance to small-sized, miniature clinical data center in building institute.
Specific embodiment
In order to which technical problems, technical solutions and advantages to be solved are more clearly understood, tie below Embodiment is closed, the present invention will be described in detail.It should be noted that specific embodiment described herein is only to explain The present invention is not intended to limit the present invention.
The clinical data group classification method based on Chinese medical main suit's analysis, comprising the following steps:
The first step is formed using main suit of the machine learning algorithm to various clinical examinations inspection data and doctor's typing Data group carries out analysis mining, obtains information and knowledge that data group implies;
Second step, the data source provided according to hospital information system carry out at analysis the main suit content of doctor's typing Reason obtains the data classification of data group in conjunction with information and knowledge that the data group got implies;
Third step, by the corresponding data category in data group deposit clinical data center relevant knowledge library.
The data source that the hospital information system provides comes from hospital HIS (Hospital Information System) System.HIS is the information management system for covering hospital all business and business overall process, is a kind of living in hospital management and medical treatment The computer application system of information management and on-line operation, english abbreviation HIS are carried out in dynamic.
Hospital HIS system includes following components:
