Problems solved by technology
At present, most of the medical records used in hospitals are used as a quick record tool, but only control the time and writing format, and there is no complete structured medical record
At the same time, the medical field has certain subjectivity and ambiguity. The terminology of different diseases will be different, and the same symptom will be expressed in different ways. Doctors also have their own writing habits, which brings great difficulties to the research work of medical records. big difficulty

[0029] The present invention conducts experiments on the clinical medical records of TCM stroke, uses Chinese word segmentation software (such as ICTCLAS2012) to segment the medical record text, and uses Protege3.4.8 to construct the ontology of TCM stroke medical records in the form of OWL DL language, and stores them in the database. Then use the Java language to build a JavaBean component with semantic text processing capabilities, filter words through regular expressions and special part-of-speech tags in word segmentation results, and use commas, spaces, and line breaks as markers for segmenting paragraphs and sentences. Then read, control and output the medical record ontology through the java semantic application class library provided by Jena and the Pellet inference engine. Use the ontology level traversal function provided by Jena to obtain the word combination of the parent class, subclass, and attribute relationship in the medical record ontology. For each word comb...

The invention provides a generation method of a structured electronic medical record based on an ontology technology, which is characterized by comprising the following steps: performing word segmentation on a medical record text to acquire a word segmentation result document, performing phrase filtering on the word segmentation result document to acquire a keyword lexicon, and constructing a medical record ontology by using an attribute relationship of a keyword class; defining an output characteristic variable format of the medical record ontology, and constructing a medical record feature index; preprocessing a clinical medical record to acquire a clinical medical record word segmentation document; and matching the clinical medical record word segmentation document with the medical record feature index, and outputting the structured electronic medical record. The generation method of the electronic medical record can retain the information in the medical record text more completely and then can better mine the information implied in the medical record.
Description
technical field [0001] The invention relates to the medical field, in particular to a method for generating structured electronic medical records based on ontology technology. Background technique [0002] Medical records are a summary of doctors' experience in using medical knowledge flexibly during long-term clinical practice. They objectively and completely record the changes in patients' conditions and the entire process of diagnosis and treatment. They are good materials for clinical teaching and scientific research. Medical records store a large amount of medical information, and digging out useful information such as disease characteristics and diagnosis and treatment plans hidden in medical records can greatly promote the development of medical technology. At present, most of the medical records used in hospitals are used as a quick record tool, but only control the time and writing format, and there is no complete structured medical record. At the same time, the me...
